In order to make the above features and advantages of the disclosure better understood, embodiments are specifically provided below with reference to figures for detailed description as follows.

DESCRIPTION OF THE EMBODIMENTS

Hereinafter, exemplary embodiments of the disclosure are described in detail, and examples of the exemplary embodiments are conveyed via the figures. Wherever possible, the same reference numerals are used in the figures and the descriptions to refer to the same or similar portions.

Throughout the disclosure, certain words are used to refer to specific elements in the specification and the claims. Those skilled in the art should understand that electronic device manufacturers may refer to the same components by different names. The present specification does not intend to distinguish between elements that have the same function but different names. In the following description and claims, the words “contain” and “include” and the like are open-ended words, and therefore should be interpreted as “including but not limited to . . . ”

In the present specification, wordings used to indicate direction, such as “up,” “down,” “front,” “back,” “left,” and “right”, merely refer to directions in the drawings. Therefore, the directional terms are used to illustrate and are not intended to limit the disclosure. In the drawings, the figures depict typical features of the methods, structures, and/or materials used in the particular embodiments. However, the figures are not to be interpreted as defining or limiting the scope or nature of the embodiments. For example, the relative size, thickness, and location of layers, regions, and/or structures may be reduced or enlarged for clarity.

A structure (or layer, element, or substrate) described in the disclosure located on/above another structure (or layer, element, or substrate) may mean that the two structures are adjacent and directly connected, or may mean that two structures are adjacent rather than directly connected. Indirect connections refer to at least one intermediate structure (or intermediate layer, intermediate element, intermediate substrate, intermediate spacing) between two structures. The lower side surface of a structure is adjacent or directly connected to the upper side surface of the intermediate structure, the upper side surface of the other structure is adjacent or directly connected to the lower side surface of the intermediate structure. The intermediate structure may be formed by a single-layer or multi-layer physical structure or a non-physical structure without limitation. In the disclosure, when a certain structure is disposed “on” other structures, it may mean that the certain structure is “directly” on other structures, or that the certain structure is “indirectly” on other structures, that is, at least one structure is further sandwiched between the certain structure and other structures.

The terms “about”, “equal to”, “equal” or “same”, “substantially” or “essentially” are generally interpreted as within 20% of the given value or range, or interpreted as within 10%, 5%, 3%, 2%, 1%, or 0.5% of a given value or range. In addition, the terms “the range is from a first value to a second value” and “the range is between a first value to a second value” mean the range includes the first value, the second value, and other values in between.

The ordinal numbers used in the specification and claims, such as “first”, “second”, etc., are used to modify an element. They do not themselves imply and represent that the element(s) have any previous ordinal number, and also do not represent the order of one element and another element, or the order of manufacturing methods. The use of these ordinal numbers is to clearly distinguish an element with a certain name from another element with the same name. The claims and the specification may not use the same terms, and accordingly, the first component in the specification may be the second component in the claims.

The electrical connection or coupling described in the disclosure may refer to direct connection or indirect connection. In the case of direct connection, the endpoints of the components on two circuits are directly connected or connected to each other via a conductor line segment. In the case of indirect connection, there are switches, diodes, capacitors, inductors, resistors, other suitable components, or a combination of the above components between the endpoints of the components on two circuits. However, the disclosure is not limited thereto.

In the disclosure, the thickness, length, and width may be measured by using an optical microscope (OM), and the thickness or width may be measured by a cross-sectional image in an electron microscope, but the disclosure is not limited thereto. Moreover, if a first direction is perpendicular to a second direction, then the angle between the first direction and the second direction may be between 80 degrees and 100 degrees; and if the first direction is parallel to the second direction, then the angle between the first direction and the second direction may be between 0 degrees and 10 degrees.

It should be noted that the following embodiments may disassemble, replace, recombine, and mix the features of several different embodiments without departing from the spirit of the disclosure to complete other embodiments. As long as the features between the embodiments do not violate the spirit of the disclosure or conflict with each other, they may be mixed and used arbitrarily.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those of ordinary skill in the art to which this disclosure belongs. It should be understood that, these terms, such as those defined in commonly used dictionaries, should be interpreted as having meaning consistent with the relevant technique and the background or context of the disclosure, and should not be interpreted in an idealized or excessively formal way, unless specifically defined in an embodiment of the disclosure.

The following description will continue with the array substrate and the filter substrate, but the disclosure is not limited thereto.

FIG.1Ashows the first substrate10seen from a top view direction (e.g., direction Z) of the electronic device1, andFIG.1Aschematically illustrates an insulating layer102, a first electronic element103, and a second electronic element104in the first substrate10, so as to make the drawing clear and concise.FIG.1Bshows the second substrate12seen from the bottom direction of the electronic device1(e.g., the opposite direction of direction Z) in an embodiment, andFIG.1Bschematically illustrates a light-shielding layer121in the second substrate12to make the drawing clear and concise. In another embodiment, when the second substrate is, for example, a cover plate, the light-shielding layer may be omitted, but the disclosure is not limited thereto.

The first substrate10may include a substrate100, a conductive layer101, an insulating layer102, a first electronic element103, and a second electronic element104, but the disclosure is not limited thereto. For example, as shown inFIG.2, the first substrate10may further include an insulating layer105, a light-shielding layer106, and an insulating layer107, but the disclosure is not limited thereto.

The substrate100may be a rigid substrate or a flexible substrate. The material of the substrate100includes, for example, glass, quartz, ceramic, sapphire, or plastic, but the disclosure is not limited thereto. The plastic may include polycarbonate (PC), polyimide (PI), polypropylene (PP), polyethylene terephthalate (PET), other suitable flexible materials, or a combination of the above materials, but the disclosure is not limited thereto.

The conductive layer101is disposed on the substrate100. The conductive layer101may include a stacked structure of a single-layer conductive layer and at least one insulating layer, a stacked structure of a multi-layer conductive layer and a multi-layer insulating layer, a redistribution layer (RDL) structure, etc., and the conductive layer101may also include an electronic element (such as a chip, an active element, and/or a passive element), and the electronic elements may be electrically connected to each other or electrically insulated, but the disclosure is not limited thereto.

The insulating layer102is disposed on the conductive layer101and may include a first opening A1and a second opening A2. The first opening A1is used for accommodating the first electronic element103, for example, and the second opening A2is used for accommodating the second electronic element104, for example. Design parameters such as the relative arrangement and quantity of the first opening A1and the second opening A2in the insulating layer102may be designed according to actual requirements (e.g., the relative arrangement and quantity of the first electronic element103and the second electronic element104). TakingFIG.1Aas an example, the insulating layer102may include a plurality of first openings A1and a plurality of second openings A2, wherein the plurality of first openings A1are arranged in an array, for example, and each of the first openings A1may be surrounded by a plurality of second openings A2, but the disclosure is not limited thereto.

When the function of at least one of the first electronic element103and the second electronic element104is related to light, for example, when at least one of the first electronic element103and the second electronic element104has the function of receiving light or emitting light, etc., the insulating layer102may include an opaque organic polymer material to reduce issues such as interference and/or light mixing between adjacent electronic elements. The opaque organic polymer material may be a white, gray, or black organic polymer material, such as a black matrix, but the disclosure is not limited thereto. In some embodiments, the insulating layer102may also include a transparent organic polymer material. The transparent organic polymer material may include resin, but the disclosure is not limited thereto.

As shown inFIG.2, the insulating layer102may have a single thickness (e.g., a thickness T102), but the disclosure is not limited thereto. Although not shown inFIG.2, the insulating layer102may have a plurality of thicknesses (described later). The thickness T102of the insulating layer102may be the maximum thickness of the insulating layer102in the direction Z in any section of the electronic device1. Under the architecture that the insulating layer102has a single thickness, a depth DA1of the first opening A1and a depth DA2of the second opening A2are the same as or similar to the thickness T102.

The first electronic element103is disposed in the first opening A1and electrically connected to the conductive layer101, and the second electronic element104is disposed in the second opening A2and electrically connected to the conductive layer101. For example, the first electronic element103and the second electronic element104may be fixed on the conductive layer101via a conductive member (not shown) and electrically connected to a corresponding circuit and/or drive unit (e.g., chip) in the conductive layer101, respectively. The conductive member may include a conductive bump (e.g., a solder ball), conductive adhesive, or an anisotropic conductive film (ACF), but the disclosure is not limited thereto.

In some embodiments, as shown inFIG.1A, one corresponding first electronic element103may be disposed in each of the first openings A1, and one corresponding second electronic element104may be disposed in each of the second openings A2. InFIG.1A, since the distribution density of the second openings A2per unit area is greater than the distribution density of the first openings A1per unit area, the distribution density of the second electronic elements104per unit area is also greater than the distribution density of the first electronic elements103per unit area. It should be understood that, design parameters such as the relative arrangement relationship and quantity of the first openings A1and the second openings A2may be changed according to actual needs, so as to change design parameters such as the relative arrangement relationship and quantity of the first electronic element103and the second electronic element104.

The first electronic element103and the second electronic element104may have different functions according to different usage requirements. For example, the functions of the first electronic element103and the second electronic element104may include two functions, such as the function of emitting light, the function of receiving light, the function of outputting/transmitting a drive signal, and the function of receiving/transmitting/adjusting/changing an electromagnetic wave. The element having the function of emitting light may be, for example, a light-emitting unit. The light-emitting unit may include an organic or inorganic light-emitting diode. In addition, the light-emitting unit may be a single-color light-emitting diode or a package of multi-color (e.g., red, green, and blue) light-emitting diodes. The element having the function of receiving light may be, for example, a photosensitive unit. The photosensitive unit may include, but not limited to, a camera unit, an image sensor, or a fingerprint sensor, but the disclosure is not limited thereto. The element having the function of outputting/transmitting a drive signal may be, for example, a drive unit. The drive unit may include, but is not limited to, a micro IC. The element having the function of receiving/transmitting/adjusting/changing an electromagnetic wave may be, for example, an antenna unit. The antenna unit may include a variable capacitance element, such as a varactor or a large-volume liquid-crystal element, but the disclosure is not limited thereto. The capacitance of the variable capacitance element or the large-volume liquid-crystal element may be changed by applying a positive bias voltage to the variable capacitance element or the large-volume liquid-crystal element, thereby controlling, for example, the frequency or direction of an electromagnetic wave. Moreover, light detection may be performed by applying a negative bias voltage to the variable capacitance element or the large-volume liquid-crystal element. In some embodiments, the first electronic element103and the second electronic element104may include two elements, such as a light-emitting unit, a photosensitive unit, a drive unit, or an antenna unit, etc., but the disclosure is not limited thereto.

The insulating layer105is disposed on the insulating layer102and covers the first electronic element103and the second electronic element104. The material of the insulating layer105includes, for example, an organic insulating material, an inorganic insulating material, or a combination thereof. The organic insulating material includes, for example, PMMA, an epoxy resin, an acrylic-based resin, silicone, a polyimide polymer, or a combination of the above, but the disclosure is not limited thereto. The inorganic insulating material includes, for example, silicon oxide or silicon nitride, but the disclosure is not limited thereto.

The light-shielding layer106may be provided when the function of at least one of the first electronic element103and the second electronic element104is related to the emission or reception of light.

The light-shielding layer106is disposed on the insulating layer105. The light-shielding layer106may be a thin metal layer or an opaque organic polymer layer. When the first electronic element103is a light-emitting unit including a function of emitting light and the second electronic element104is a photosensitive unit including a function of receiving light, the light-shielding layer106may include a third opening A3and a fourth opening A4. In the top view of the electronic device1, the third opening A3is overlapped with the first opening A1, and the fourth opening A4is overlapped with the second opening A2. In other words, the third opening A3is at least partially overlapped with the first opening A1in the direction Z, and the fourth opening A4is at least partially overlapped with the second opening A2in the direction Z.

The third opening A3of the light-shielding layer106is disposed corresponding to the first electronic element103and may be used as a light channel of the first electronic element103to allow the light from the first electronic element103(such as the light-emitting unit) to pass through. Therefore, the light generated by the first electronic element103may pass through the first opening A1and the third opening A3in sequence and have a chance to be output from the electronic device1. The fourth opening A4of the light-shielding layer106is disposed corresponding to the second electronic element104(such as a photosensitive unit) and may be used as a light channel for the second electronic element104to allow light incident toward the second electronic element104(such as external light or light reflected by the fingerprint) to pass through, so that light incident toward the second electronic element104may pass through the fourth opening A4and the second opening A2in sequence and have a chance to be received by the second electronic element104.

The third opening A3may be designed to be a larger opening than the first opening A1, so as to reduce the shielding of the light emitted by the light-emitting unit by the light-shielding layer106, thereby increasing the amount of light output from the electronic device1. Moreover, the fourth opening A4may be designed to be less than the second opening A2to collimate light incident toward the second electronic element104and reduce interference of large-angle stray light to the second electronic element104. For example, a width WA3of the third opening A3may be greater than a width WA1of the first opening A1and a width WA4of the fourth opening A4, and the width WA4of the fourth opening A4may be less than a width WA2of the second opening A2.

In the present specification, the relative size relationship of the opening widths may be compared from the same section or from different sections. When viewed from the cross-sectional view, the width of the bottom portion of the opening in the section is taken as the width of the opening. When viewed from the top view, if the shape of the opening is an ellipse, the length of the major axis and the length of the minor axis of the ellipse are added and divided by two as the width of the opening. If the shape of the opening is irregular, the length of the diagonal of the smallest rectangle covering the opening is taken as the width of the opening.

The insulating layer107is disposed on the light-shielding layer106. For the material of the insulating layer107, reference may be made to the material of the insulating layer105, which is not repeated herein.

In an embodiment, the second substrate12may include a substrate120, the light-shielding layer121, and an insulating layer124, but the disclosure is not limited thereto. The second substrate12may be provided with or omit one or a plurality of elements or film layers according to different requirements. For example, when the function of at least one of the first electronic element103and the second electronic element104is related to the emission or reception of light, the second substrate12may further include a light converting element122and a light filter unit123, but the disclosure is not limited thereto. In another embodiment, the light-shielding layer121may be disposed on the insulating layer107, and the insulating layer124may be disposed between the light-shielding layer121and the insulating layer107according to different requirements, or an insulating layer may be disposed on the light-shielding layer121, but the disclosure is not limited thereto. Then, the substrate120is disposed on the light-shielding layer121to serve as a cover plate, but the disclosure is not limited thereto.

The substrate120is disposed opposite to the substrate100. The substrate120may be a rigid substrate or a flexible substrate. For the material of the substrate120, reference may be made to the material of the above substrate100, which is not repeated herein.

In an embodiment, the light-shielding layer121is disposed on the surface of the substrate120facing the substrate100. The material of the light-shielding layer121may include a light-absorbing material, such as a black matrix, but the disclosure is not limited thereto. The light-shielding layer121may include a fifth opening A5and a sixth opening A6corresponding to the third opening A3and the fourth opening A4, respectively. In other words, the fifth opening A5is at least partially overlapped with the third opening A3in the direction Z, and the sixth opening A6is at least partially overlapped with the fourth opening A4in the direction Z.

In some embodiments, a width WA5of the fifth opening A5may be greater than or equal to the width WA3of the third opening A3, so as to reduce the shielding of the light penetrating the third opening A3by the light-shielding layer121to enable light from the third opening A3to be transmitted upward and have a chance to be output from the electronic device1, but the disclosure is not limited thereto. In some embodiments, the width WA5of the fifth opening A5may be less than the width WA3of the third opening A3. Moreover, the relative size relationship between a width WA6of the sixth opening A6and the width WA4of the fourth opening A4may not be limited. That is, the width WA6of the sixth opening A6may be less than, equal to, or greater than the width WA4of the fourth opening A4.

The light converting element122is disposed in the fifth opening A5. The light converting element122may be used to change the color or waveband of incident light. The material of the light converting element122includes, for example, fluorescence, phosphorescence, quantum dots, other suitable light converting materials, light filter materials (such as color resists), or a combination of the above, but the disclosure is not limited thereto. In some other embodiments, although not shown inFIG.2, the light converting element122may be disposed in the third opening A3of the light-shielding layer106, so that the fifth opening A5may not be provided with a light converting element or may be provided with another light converting element. For example, the material of the light converting element in the third opening A3may be fluorescence, phosphorescence, quantum dots, or a combination of the above, and the material of the light converting element in the fifth opening A5may be a light filter material, but the disclosure is not limited thereto. In still other embodiments, a transparent polymer material may be used instead of the light converting element122to be disposed in the fifth opening A5. For example, when the light-emitting unit is a blue light-emitting diode, in the red pixel, a red light converting element may be disposed in the fifth opening A5, in the green pixel, a green light converting element may be disposed in the fifth opening A5, and in the blue pixel, a transparent polymer material or a blue light filter material may be disposed in the fifth opening A5, but the disclosure is not limited thereto. In the following embodiments, the arrangement position or type of the light converting element122may be changed as in the above, and is not repeated herein.

The light filter unit123is disposed in the sixth opening A6, so that the light filter unit123in the direction Z is at least partially overlapped with the second electronic element104(e.g., the photosensitive element). The light filter unit123helps to filter stray light in the environment, thereby improving the recognition degree of the photosensitive element. In some embodiments, the light filter unit123may be a green light filter unit to filter red light or near-infrared light in the environment, but the disclosure is not limited thereto. In other embodiments, although not shown inFIG.2, the light filter unit123may not be disposed on the second substrate12. In the following embodiments, the type or setting of the light filter unit123may be changed as described above, and is not repeated herein.

In an embodiment, the insulating layer124is disposed on the surface of the light-shielding layer121facing the substrate100and covers the light converting element122and the light filter unit123. The material of the insulating layer124may include an organic insulating material, such as polymethyl methacrylate, epoxy resin, acrylic resin, silicone, polyimide polymer, or a combination of the above, but the disclosure is not limited thereto.

The conductive layer101is formed on the substrate100(step S2). The insulating layer102is formed on the conductive layer101, and the insulating layer102is patterned to form the first opening A1and the second opening A2(step S3). The first electronic element103is disposed in the first opening A1and electrically connected to the conductive layer101(step S4). The second electronic element104is disposed in the second opening A2and electrically connected to the conductive layer101(step S5), wherein the first electronic element103and the second electronic element104have different functions. In some embodiments, as shown inFIG.3, the manufacturing method of the electronic device1may further include the following steps. The light-shielding layer106is formed on the insulating layer102, and the light-shielding layer106is patterned to form the third opening A3(step S6). The light converting element122is formed in the third opening A3(step S7). The second substrate12is attached (step S8), but the disclosure is not limited thereto.

In detail, for step S1, as shown inFIG.4A, the substrate100may be provided. For the material of the substrate100, please refer to the above, which is not repeated herein.

For step S4and step S5, as shown inFIG.4DandFIG.4E, the first electronic element103is disposed in the first opening A1and electrically connected to the conductive layer101, and the second electronic element104is disposed in the second opening A2and electrically connected to the conductive layer101. Under the structure in which the first electronic element103is a light-emitting unit and the second electronic element104is a photosensitive unit, the first electronic element103and the second electronic element104are electrically insulated from each other, for example, and the first electronic element103and the second electronic element104are electrically connected to different circuits (not shown) in the conductive layer101, for example, respectively.

Although not shown, the sequence of step S4and step S5may be reversed. That is, the second electronic element104may be disposed in the second opening A2first, and then the first electronic element103may be disposed in the first opening A1.

After the first electronic element103and the second electronic element104are disposed, the insulating layer105may be formed next, and the insulating layer105may be, for example, a flat layer to provide a flat surface, in order to reduce the difficulty of the subsequent process (e.g., forming the light-shielding layer106) or improve the yield of the subsequent process, but the disclosure is not limited thereto. For the material of the insulating layer105, please refer to the above, which is not repeated herein.

For step S6, as shown inFIG.4F, the light-shielding layer106is formed on the insulating layer105. For example, an entire light-shielding layer may be formed first, and then the third opening A3and the fourth opening A4may be formed via a patterning process to form the light-shielding layer106.

For step S7, although not shown inFIG.4ForFIG.4G, a light converting element (such as the light converting element122shown inFIG.2) may be formed in the third opening A3, and thus, the fifth opening A5in the second substrate12(refer to FIG.4G) may not be provided with a light converting element, or another light converting element (such as a light filter unit) may be disposed in the fifth opening A5in the second substrate12. Alternatively, as shown inFIG.4G, the light converting element122may be disposed in the fifth opening A5in the second substrate12, and thus, the manufacturing method of the electronic device1may omit step S7.

Next, the insulating layer107may be further formed on the light converting element (if any), the light-shielding layer106, and the insulating layer105. For the material of the insulating layer107, please refer to the above, which is not repeated herein. As a result, the manufacture of the first substrate10is preliminarily completed.

In another embodiment, the light-shielding layer121may be further formed on the insulating layer107, and the light-shielding layer121may be patterned to form the fifth opening A5and/or the sixth opening A6. Then, the light converting element122may be disposed in the fifth opening A5and/or the light filter unit123may be disposed in the sixth opening A6, respectively. Next, an insulating layer may be optionally formed on the light-shielding layer121to complete the manufacture of the first substrate10.

For step S8, as shown inFIG.4G, the second substrate12is attached onto the first substrate10. For example, the second substrate12may be fixed on the first substrate via a bonding layer (not shown; such as an adhesive layer), but the disclosure is not limited thereto. In another embodiment, the second substrate12may include the substrate120and be fixed on the first substrate10, but the disclosure is not limited thereto.

Referring toFIG.5AandFIG.5B, the method of disposing the first electronic element103and the second electronic element104into the first opening A1and the second opening A2is, for example, via at least one transfer equipment or fixture, and the transfer equipment or fixture includes at least one transfer head for transferring the first electronic element103and the second electronic element104, but the disclosure is not limited thereto.

When the first electronic element103and the second electronic element104have different functions, the first electronic element103and the second electronic element104may have different thicknesses. When the electronic elements are packaged to form electronic modules, different electronic modules may have different heights. Since the thicknesses of the first electronic element103and the second electronic element104are different or the heights of the resulting electronic modules are different, for example, a thickness T103of the first electronic element103is greater than a thickness T104of the second electronic element104, the insulating layer102has a single thickness T102, and the thickness T102of the insulating layer102is, for example, greater than the thickness T104of the second electronic element104and less than the thickness T103of the first electronic element103, and the first electronic element103and the second electronic element104may be transferred respectively via two transfer equipment or fixtures (such as the transfer head T1and the transfer head T2) in order to reduce the probability that the transfer equipment or the fixture is in contact with the insulating layer102during the process of transferring the electronic elements (such as the first electronic element103or the second electronic element104). Thereby, the integrity of the insulating layer102or the bonding degree between the electronic elements and the conductive layer101is maintained.

Referring toFIG.6, the main difference between an electronic device1A and the electronic device1ofFIG.2is that an insulating layer102A inFIG.6has a plurality of thicknesses. For example, the insulating layer102A having a plurality of thicknesses may be formed via a grayscale mask, but the disclosure is not limited thereto.

In detail, the thickness of the insulating layer102A is designed, for example, according to the thicknesses of the first electronic element103and the second electronic element104. TakingFIG.6as an example, a thickness T102-1of the insulating layer102A adjacent to the first opening A1may be designed to be slightly less than the thickness T103of the first electronic element103, and a thickness T102-2of the insulating layer102A adjacent to the second opening A2may be designed to be slightly less than the thickness T104of the second electronic element104. In this way, the first electronic element103and the second electronic element104may be transferred via a single transfer equipment or fixture.

As shown inFIG.6, since the thickness T103of the first electronic element103is greater than the thickness T104of the second electronic element104, and the thickness T102-1of the insulating layer102A adjacent to the first opening A1is greater than the thickness T102-2of the insulating layer102A adjacent to the second opening A2, wherein a depth DA1of the first opening A1is substantially equal to 0.95 times the thickness T102-1of the insulating layer102A at the first opening A1, a depth DA2of the second opening A2is substantially equal to 0.95 times the thickness T102-2of the insulating layer102A at the second opening A2, and the depth DA1of the first opening A1is greater than the depth DA2of the second opening A2. Specifically, along the direction Z, the thickness of the insulating layer102A measured from the substantially flat top surface adjacent to the first opening A1to the bottom surface adjacent to the conductive layer101is 0.95 times the depth of the first opening A1(calculated from the bottom surface of the insulating layer102A adjacent to the conductive layer101). Such a measurement method may be applied to the measurement of the depths of all openings of the disclosure, but the disclosure is not limited thereto. In some embodiments, the depth and/or width of the first opening A1and the second opening A2may be measured from the same cross-section or from different cross-sections, but the disclosure is not limited thereto.

The single-thickness insulating layer in any of the following embodiments may be changed into a plurality of thickness insulating layers as described above, which is not repeated herein.

Referring toFIG.7andFIG.8A, the main differences between the manufacturing method of an electronic device1B shown inFIG.7andFIG.8Aand the manufacturing method of the electronic device1shown inFIG.3andFIG.4Gare described below. After the conductive layer101is formed (step S2), a coating film or a coating process may be used to form an entire insulating layer102B, and then the first opening A1, the second opening A2, and a seventh opening A7are formed via a patterning process (step S3′).

In some embodiments, although not shown, the insulating layer102B may have a single thickness. Alternatively, as shown inFIG.8A, the insulating layer102B may have a plurality of thicknesses. In detail, the thickness of the insulating layer102B is designed, for example, according to the thicknesses of the first electronic element103, the second electronic element104, and a third electronic element108. TakingFIG.8Aas an example, the thickness T102-1of the insulating layer102B at the first opening A1is designed to be slightly less than the thickness T103of the first electronic element103, the thickness T102-2of the insulating layer102B at the second opening A2is designed to be slightly less than the thickness T104of the second electronic element104, and a thickness T102-3of the insulating layer102B at the seventh opening A7is designed to be slightly less than a thickness T108of the third electronic element108. In this way, the first electronic element103, the second electronic element104, and the third electronic element108may be transferred via a single transfer equipment or fixture.

As shown inFIG.8A, since the thickness T108of the third electronic element108is greater than the thickness T103of the first electronic element103, and the thickness T103of the first electronic element103is greater than the thickness T104of the second electronic element104, the thickness T102-3of the insulating layer102B at the seventh opening A7is greater than the thickness T102-1of the insulating layer102B at the first opening A1, and the thickness T102-1of the insulating layer102B at the first opening A1is greater than the thickness T102-2of the insulating layer102B at the second opening A2, wherein the depth DA1of the first opening A1is equal to 0.95 times the thickness T102-1of the insulating layer102B at the first opening A1, the depth DA2of the second opening A2is equal to 0.95 times the thickness T102-2of the insulating layer102B at the second opening A2, the depth DA7of the seventh opening A7is equal to 0.95 times the thickness T102-3of the insulating layer102B at the seventh opening A7, the depth DA7of the seventh opening A7is greater than the depth DA1of the first opening A1, and the depth DA1of the first opening A1is greater than the depth DA2of the second opening A2.

Moreover, before the light-shielding layer106is formed (step S6), the third electronic element108is disposed in the seventh opening A7and electrically connected to the conductive layer101(step S9). The third electronic element108may be, for example, a drive unit having the function of outputting/transmitting a drive signal, and the third electronic element108may be electrically connected to at least one of the first electronic element103and the second electronic element104via the conductive layer101, but the disclosure is not limited thereto.

AlthoughFIG.7shows that the first electronic element103is transferred onto the conductive layer101before the second electronic element104and the second electronic element104is transferred onto the conductive layer101before the third electronic element108, the transfer sequence of the first electronic element103, the second electronic element104, and the third electronic element108may be changed according to actual needs, and is not limited to what is shown inFIG.7. For example, based on factors such as yield or cost, electronic elements with higher distribution density or less thickness may be transferred first. TakingFIG.8Aas an example, the first electronic element103, the second electronic element104, and the third electronic element108are, for example, a light-emitting unit, a photosensitive unit, and a drive unit, respectively, and the transfer steps of various electronic elements are, for example, firstly transferring the second electronic element104, then transferring the first electronic element103, and lastly transferring the third electronic element108, but the disclosure is not limited thereto. In other embodiments, although not shown, the first electronic element103, the second electronic element104, and the third electronic element108are, for example, an antenna unit, a light-emitting unit, and a drive unit, respectively, and the transfer steps of the electronic elements are, for example, firstly transferring the first electronic element103, then transferring the second electronic element104, and lastly transferring the third electronic element108, but the disclosure is not limited thereto.

Since the function of the third electronic element108has nothing to do with light, in the patterning step of the light-shielding layer106(step S6), a light channel does not need to be formed corresponding to the third electronic element108. That is, an opening corresponding to the third electronic element108does not need to be formed in the light-shielding layer106. Similarly, an opening corresponding to the third electronic element108does not need to be formed in the light-shielding layer121in the second substrate12.

After the light-shielding layer106having the third opening A3and the fourth opening A4is formed (step S6), the light converting element125may then be formed in the third opening A3(step S7), and then the second substrate12is attached onto the first substrate10(step S8). In this way, the manufacture of the electronic device1B is preliminarily completed. In the electronic device1B, the light converting element125in the third opening A3and the light converting element122in the fifth opening A5may have different materials. For example, the material of the light converting element125may include fluorescence, phosphorescence, quantum dots, or a combination thereof, and the material of the light converting element122may be a light filter material, but the disclosure is not limited thereto. In other embodiments, although not shown inFIG.8A, the electronic device1B may include a single light converting element (e.g., the light converting element125or the light converting element122). Under this architecture, the material of the light converting element may include fluorescence, phosphorescence, quantum dots, other suitable light converting materials, light filter materials (such as color resists), or a combination of the above, but the disclosure is not limited thereto.

In other embodiments, although not shown, the electronic device1B may further include a fourth electronic element, wherein the first electronic element103, the second electronic element104, the third electronic element108, and the fourth electronic element are, for example, a light-emitting unit, a photosensitive unit, a drive unit, and an antenna unit, respectively, but the disclosure is not limited thereto. Correspondingly, the insulating layer102B may further include an opening (e.g., an eighth opening) for accommodating the fourth electronic element. The insulating layer102B may have a single thickness or a plurality of thicknesses. For example, the transfer step of a plurality of electronic elements is to transfer the second electronic element104, the fourth electronic element, the first electronic element103, and the third electronic element108in sequence. Alternatively, the fourth electronic element, the second electronic element104, the first electronic element103, and the third electronic element108are transferred in sequence, but the disclosure is not limited thereto. Since the function of the fourth electronic element is related to light (or electromagnetic wave), the light-shielding layer106further includes, for example, an opening (e.g., a ninth opening) corresponding to the fourth electronic element. The ninth opening is at least partially overlapped with the eighth opening in the direction Z, and the ninth opening may be designed as a larger opening (e.g., larger than the first opening A1) to reduce the shielding of light (or electromagnetic wave) by the light-shielding layer106. Similarly, the light-shielding layer121in the second substrate12further includes, for example, an opening (e.g., a tenth opening) corresponding to the fourth electronic element. The tenth opening is at least partially overlapped with the ninth opening in the direction Z, and the relative size relationship between the tenth opening and the seventh opening may not be limited.

Please refer toFIG.8B. The main differences between an electronic device1C and the electronic device1B ofFIG.8Aare described below. The electronic device1C also includes a plurality of connecting elements14and a drive unit16. The plurality of connecting elements14penetrate through the substrate100and are electrically connected to the drive unit16. The drive unit16may include a controller (e.g., the third electronic element108) and a redistribution layer structure141. The redistribution layer structure141is disposed on the third electronic element108and electrically connected to the third electronic element108. The redistribution layer structure141includes, for example, a plurality of insulating layers IN, a plurality of conductive layers CL, and a plurality of connecting elements P. The plurality of insulating layers IN and the plurality of conductive layers CL are alternately disposed on the third electronic element108. The conductive layer CL may be formed by first forming the conductive layer and then performing a patterning process. Each of the connecting elements P penetrates one or a plurality of insulating layers IN to electrically connect two corresponding conductive layers CL. The plurality of connecting elements14penetrating the substrate100, for example, electrically connect the conductive layer101to the conductive layer CL closest to the substrate100. The material of the insulating layer IN includes, for example, silicon oxide or silicon nitride, but the disclosure is not limited thereto. The material of the conductive layer CL and the connecting element14includes, for example, metal, alloy, or a combination thereof, but the disclosure is not limited thereto. The material of the conductive layer CL and the connecting element14may be the same or different.

In some embodiments, the drive unit16may also include an encapsulation layer140to protect the controller (e.g., the third electronic element108). For example, the encapsulation layer140surrounds the third electronic element108and exposes a surface S108of the third electronic element108facing the substrate100. The material of the encapsulation layer140includes, but not limited to, silicon oxide, silicon nitride, or acrylic-based polymer material, for example.

In some embodiments, after the second substrate12is attached onto the first substrate10, the plurality of connecting elements14penetrating the substrate100are formed in the substrate100, and then the drive unit16is joined to the plurality of connecting elements14. Or, the plurality of connecting elements14may be manufactured in the step of forming the conductive layer101, and then after the second substrate12is attached onto the first substrate10, the drive unit16may be joined with the plurality of connecting elements14.

By disposing the third electronic element108in the drive unit16, the seventh opening A7does not need to be formed in the insulating layer102. Moreover, the insulating layer102may have a single thickness (e.g., the thickness T102), but the disclosure is not limited thereto. In other embodiments, the insulating layer102may be replaced with the insulating layer102A having a plurality of thicknesses as shown inFIG.6.

Please refer toFIG.8C. The main differences between an electronic device1D and the electronic device1C ofFIG.8Bare described below. In the electronic device1D, the third electronic element108, the encapsulation layer140, and the redistribution layer structure141are disposed in the first substrate10D. Specifically, the third electronic element108and the encapsulation layer140are disposed on the substrate100, and the redistribution layer structure141is disposed between the third electronic element108(and the encapsulation layer140) and the conductive layer101. Via the above design, the electronic device1D may omit the plurality of connecting elements14.

Moreover,FIG.10omits the second substrate12(refer toFIG.8C) and the insulating layer102(refer toFIG.8C), so please refer toFIG.8Cfor the description of the second substrate12and the insulating layer102below.

For example, the manufacturing method of the electronic device lE includes the following steps. The third electronic element108is provided (step S10). A conductive layer is formed on the third electronic element108, for example, the redistribution layer structure141is formed on the third electronic element108(step S11). The insulating layer102is formed on the conductive layer (e.g., the redistribution layer structure141), and the insulating layer102is patterned to form the first opening A1and the second opening A2(step S3). The first electronic element103is disposed in the first opening A1and electrically connected to the conductive layer (e.g., the redistribution layer structure141) (step S4). The second electronic element104is disposed in the second opening A2and electrically connected to the conductive layer (e.g., the redistribution layer structure141) (step S5). The light-shielding layer106is formed on the insulating layer102, and the light-shielding layer106is patterned to form the third opening A3and the fourth opening A4(step S6). An optical structure109is formed (step S12). An encapsulation layer110is formed on the optical structure109(step S13). The third electronic element108is bonded to the conductive layer101on the substrate100(step S14). The second substrate12is attached (step S8). However, the disclosure is not limited thereto.

In detail, for step S10, the third electronic element108may be provided. Then, the encapsulation layer140may be formed on the third electronic element108. The encapsulation layer140surrounds the third electronic element108and exposes the surface S108of the third electronic element108facing the substrate100.

For step S11, a conductive layer (e.g., the redistribution layer structure141) may be formed on the encapsulation layer140, wherein the connecting elements P may penetrate the encapsulation layer140to electrically connect the third electronic element108to the corresponding conductive layer CL.

For step S6, one light-shielding layer106and one insulating layer107, or a plurality of light-shielding layers106and a plurality of insulating layers107may be alternately formed on the insulating layer102and the insulating layer105.FIG.10schematically illustrates two light-shielding layers106and two insulating layers107, but the respective numbers of the light-shielding layers106and the insulating layers107are not limited thereto. For example, the numbers of the light-shielding layers106and the insulating layers107may be greater than or equal to three. In addition, the third openings A3(or the fourth openings A4) of different layers may have the same or different sizes.

For step S12, the optical structure109is formed on the insulating layer107. For example, the optical structure109is disposed corresponding to the photosensitive unit (e.g., the second electronic element104). That is, the optical structure109in the direction Z is at least partially overlapped with the photosensitive unit (e.g., the second electronic element104). The light incident toward the second electronic element104may be collected using the optical structure109to help to improve the amount of light received by the second electronic element104or the recognition degree of the second electronic element104. The shape of the optical structure109is, for example, a hemisphere, and the hemisphere generally refers to a non-complete sphere, and is not limited to half of a sphere. The material of the optical structure109includes, for example, but not limited to, a polymer material. The refractive index of the optical structure109is greater than the refractive indices of the encapsulation layer110, the insulating layer107, and the insulating layer105.

After the steps shown inFIG.15Eare completed, the manufacture of the electronic device1G is preliminarily completed.

The first electronic element103is a light-emitting unit including a function of emitting light and the second electronic element104is a photosensitive unit including a function of receiving light, and the first electronic element103is electrically insulated from the second electronic element104. However, it should be understood that, the functions of the first electronic element103and the second electronic element104may be reversed. When the first electronic element103has the function of receiving light, the width WA3of the third opening A3is, for example, less than the width WA1of the first opening A1, so as to collimate light or filter stray light. Or, the functions of the first electronic element103and the second electronic element104may be other functions. For example, the first electronic element103may be a varactor diode capable of regulating an electromagnetic wave by changing capacitance value, and the first electronic element103has the function of adjusting the capacitance value of the first electronic element103. Or, the first electronic element103may have the function of controlling the second electronic element104. For example, the first electronic element103may be used to drive, turn off, adjust, or change the state of the second electronic element104, and the first electronic element103is electrically connected to the second electronic element104via the conductive layer101, but the disclosure is not limited thereto.
