## Background
TECHNICAL FIELD
The present invention relates generally to an integrated circuit packaging system, and more particularly to a system for an integrated circuit packaging system with dual side connection.
BACKGROUND ART
Increased miniaturization of components, greater packaging density of integrated circuits (“ICs”), higher performance, and lower cost are ongoing goals of the computer industry. Semiconductor package structures continue to advance toward miniaturization, to increase the density of the components that are packaged therein while decreasing the sizes of the products that are made therefrom. This is in response to continually increasing demands on information and communication products for ever-reduced sizes, thicknesses, and costs, along with ever-increasing performance.
These increasing requirements for miniaturization are particularly noteworthy, for example, in portable information and communication devices such as cellular phones, hands-free cellular phone headsets, personal data assistants (“PDA's”), camcorders, notebook computers, and so forth. All of these devices continue to be made smaller and thinner to improve their portability. Accordingly, large-scale IC (“LSI”) packages that are incorporated into these devices are required to be made smaller and thinner. The package configurations that house and protect LSI require them to be made smaller and thinner as well.
Consumer electronics requirements demand more integrated circuits in an integrated circuit package while paradoxically providing less physical space in the system for the increased integrated circuits content. Continuous cost reduction is another requirement. Some technologies primarily focus on integrating more functions into each integrated circuit. Other technologies focus on stacking these integrated circuits into a single package. While these approaches provide more functions within an integrated circuit, they do not fully address the requirements for performance, integration, and cost reduction.
Thus, a need still remains for an integrated circuit packaging system providing improved chip interconnection and space savings. In view of the ever-increasing commercial competitive pressures, along with growing consumer expectations and the diminishing opportunities for meaningful product differentiation in the marketplace, it is critical that answers be found for these problems. Additionally, the need to reduce costs, improve efficiencies and performance, and meet competitive pressures adds an even greater urgency to the critical necessity for finding answers to these problems.
Solutions to these problems have been long sought but prior developments have not taught or suggested any solutions and, thus, solutions to these problems have long eluded those skilled in the art.

Referring now to FIG. 1, therein is shown a top view of an integrated circuit packaging system 100 in a first embodiment of the present invention. The integrated circuit packaging system 100 can have a configuration of a packaging system, which can include a dual-faced package-on-package (PoP) system with etched frames and vertical interconnects (also known as z-interconnects).
The integrated circuit packaging system 100 can include an encapsulation 124, defined as a cover of a semiconductor package that seals electrical components and provides mechanical and environmental protection. The integrated circuit packaging system 100 can include a support terminal 126, defined as an interconnect having a conductive structure that provides physical support and electrical connectivity to external systems (not shown).
The support terminal 126 can include a lead 128, defined as a portion of the support terminal 126 that provides electrical connectivity to external systems. The lead 128 can be more specifically a bond finger, a lead finger, or a contact pad.
For illustrative purposes, the lead 128 is shown with a rectangular shape, although the lead 128 can be formed in different shapes. For example, the lead 128 can have a shape of a square, a triangle, a polygon, a parallelogram, or a rhombus.
The support terminal 126 can include a contact 130, defined as a portion of the support terminal 126 that provides mounting support and electrical connectivity to external systems. For example, the contact 130 can be a lead, a contact pad, or an electrical contact. Also for example, the contact 130 can be a redistributed lead.
The contact 130 can be formed in an area array adjacent to and between a number of the lead 128. The contact 130 can be connected to the lead 128.
For illustrative purposes, the contact 130 is shown in a full area array, although the contact 130 can be formed in a different configuration. For example, the contact 130 can be formed in a peripheral array adjacent to the lead 128.
Also for illustrative purposes, the contact 130 is shown with a circular shape, although the contact 130 can be formed in different shapes. For example, the contact 130 can have a shape of a square, a rectangle, a triangle, a polygon, a parallelogram, or a rhombus.
The support terminal 126 can include a trace 134, defined as an electrical connection between the lead 128 and the contact 130. For example, the trace 134 can be a signal trace or a wire.
The trace 134 can be formed in different configurations. For example, the trace 134 can be formed with different lengths. A length of the trace 134 can be predetermined based on locations of the lead 128 and the contact 130, a distance between the lead 128 and the contact 130, a routing area that is used to form the trace 134, or a combination thereof.
The lead 128 can be formed in a row. For illustrative purposes, the lead 128 is shown in two rows along non-horizontal sides 144 of the encapsulation 124, although the lead 128 can be formed in a different configuration. For example, the lead 128 can be formed in four rows along the non-horizontal sides 144.
The lead 128 can be formed at a distance from the non-horizontal sides 144. The lead 128 can be formed with a side at the distance from the non-horizontal sides 144 and an opposite side connected to the trace 134.
Referring now to FIG. 2, therein is shown a cross-sectional view of the integrated circuit packaging system 100 along a section line 2-2 of FIG. 1. The integrated circuit packaging system 100 can include a package carrier 202. The package carrier 202 is for mounting and connecting devices and integrated circuits as part of a finished product to be used in a system.
The package carrier 202 can be more specifically a substrate. For example, the package carrier 202 can be as a laminated substrate or a ceramic substrate.
The package carrier 202 can have a first side 204 and a second side 206 opposite to the first side 204. The package carrier 202 can include a carrier pad 208, more specifically a contact pad, a lead, or an electrical contact, at the first side 204.
An integrated circuit 214, more specifically a flip-chip, an integrated circuit die, a semiconductor device, or a chip, can be mounted over the first side 204. An internal interconnect 220, more specifically a ball, a bump, or an electrical connector, can be electrically connected to the first side 204 and the integrated circuit 214. The internal interconnect 220 can be formed with solder, a metallic alloy, or a conductive material.
The encapsulation 124 can be formed over the first side 204 covering the integrated circuit 214 and the internal interconnect 220. The support terminal 126 can include the lead 128, the contact 130, and the trace 134. The contact 130 can be on the encapsulation 124 and over the integrated circuit 214.
The support terminal 126 can include a vertical pillar 235, defined as a conductive portion that provides electrical connectivity between horizontal planes of the integrated circuit packaging system 100. The vertical pillar 235 can be connected to the lead 128.
The vertical pillar 235 can be integral with the lead 128, the contact 130, and the trace 134. In other words, the vertical pillar 235, the lead 128, the contact 130, and the trace 134 can be formed of a common material having characteristics being formed from a single integrated structure or a solid structure.
The vertical pillar 235 can be mounted through the encapsulation 124. The vertical pillar 235 can be mounted on the carrier pad 208. The vertical pillar 235 can be formed with a vertical structure, which is perpendicularly to the contact 130 and the trace 134.
The vertical pillar 235 can be adjacent to the non-horizontal sides 144 of the encapsulation 124. The vertical pillar 235 can be at the distance from the non-horizontal sides 144. The vertical pillar 235 can be encapsulated or covered by the encapsulation 124.
Referring now to FIG. 3, therein is shown a cross-sectional view of the integrated circuit packaging system 100 in a pressing phase of manufacture. The integrated circuit packaging system 100 can include the package carrier 202 and the integrated circuit 214 attached thereto with the internal interconnect 220.
For illustrative purposes, the integrated circuit packaging system 100 is shown with the integrated circuit 214 mounted over the package carrier 202, although there can be any number and any type of components. For example, the integrated circuit packaging system 100 can include an active device and a passive device mounted over the package carrier 202.
The integrated circuit packaging system 100 can include the encapsulation 124 in a manufacturing step. The encapsulation 124 can be formed with a penetrable encapsulant, defined as a material having characteristics of being curable, flowable, and thermally conductive. The penetrable encapsulant can be more specifically a penetrable film adhesive, a B-stage wire in film (WIF) adhesive, a viscous gel, or any other penetrable encapsulation material.
A conductive frame 304 is defined as a structure that provides physical support and electrical connectivity. The conductive frame 304 can be formed with a metal, a metallic alloy, or a conductor. For example, the conductive frame 304 can be formed with a roller copper sheet or a leadframe.
The conductive frame 304 can include the vertical pillar 235 and a horizontal cover 306, defined as a solid layer of a conductive material that provides protection and support for mounting external systems. For example, the horizontal cover 306 can include a material that can be etched or patterned in subsequent process steps. The vertical pillar 235 can be perpendicularly connected to the horizontal cover 306.
The conductive frame 304 can be formed with the vertical pillar 235 integral with the horizontal cover 306. In other words, the conductive frame 304 can be formed with the vertical pillar 235 and the horizontal cover 306 as a single integrated structure or a solid structure.
As shown with arrows, the encapsulation 124 and the conductive frame 304 thereover can be formed by a pressing method. The pressing method refers to a method that uses heat and applies a pressure to mount the conductive frame 304 and form the encapsulation 124. The pressing method can exclude an injection molding method.
The pressing method can be used to apply a downward pressure to the conductive frame 304 and the encapsulation 124 such that the encapsulation 124 is forced onto the package carrier 202. For example, the pressing method can include a heat-pressing process, thermocompression, or any other encapsulation processes that include heat and pressure.
The pressing method can force the vertical pillar 235 through the encapsulation 124 and on the package carrier 202. The horizontal cover 306 can be on the encapsulation 124 and over the integrated circuit 214.
The encapsulation 124 can be pressed onto the package carrier 202 and with the integrated circuit 214 therein. The pressing method can allow the encapsulation 124 to flow and fill a space between the package carrier 202 and the conductive frame 304, covering the integrated circuit 214 and the internal interconnect 220.
As an example, the pressing method can be performed at a temperature of approximately 200 degrees Celsius (° C.). As another example, the pressing method can be performed with a pressure of approximately 5 megapascals (MPa).
Contamination can be avoided when connecting or joining the vertical pillar 235 to the carrier pad 208 with the encapsulation 124 between the package carrier 202 and the vertical pillar 235. For example, contamination can be avoided by the vertical pillar 235 having a flat bottom surface and the carrier pad 208 having a flat top surface, cleaning (e.g. by plasma) the vertical pillar 235 and the carrier pad 208 prior to joining, or a joining process performed in clean environment (e.g. vacuum chamber).
Prior to mounting the conductive frame 304, an attach layer (not shown), more specifically an adhesive paste, an epoxy, or an adhesive, can be deposited on the carrier pad 208. With the conductive frame 304 mounted, the vertical pillar 235 can be connected to the carrier pad 208 with the attach layer.
Referring now to FIG. 4, therein is shown the structure of FIG. 3 in a curing phase. With the horizontal cover 306 on the encapsulation 124 and the vertical pillar 235 connected to the carrier pad 208, the encapsulation 124 can be further processed with a curing method.
The curing method can include a process that solidifies or hardens the encapsulation 124. With the encapsulation 124 cured, the integrated circuit 214 and the internal interconnect 220 can be encapsulated and protected. Curing of the encapsulation 124 can also strengthen the attachment between the integrated circuit 214 and the package carrier 202 as well as the attachment or bonding between the vertical pillar 235 and the carrier pad 208.
Referring now to FIG. 5, therein is shown the structure of FIG. 4 in a patterning phase. The support terminal 126 can be formed from the horizontal cover 306 of FIG. 3. More specifically, a patterning process can be used to form the lead 128, the contact 130, and the trace 134 from the horizontal cover 306.
The patterning process can include lithography, etching methods, or any other removal processes. For example, the patterning process can include etching, stamping, cutting, chemical milling, or any combination thereof.
Following the patterning process, back-end processes can be performed. For example, the back-end processes can include marking and singulation.
After the patterning process, the lead 128, the contact 130, and the trace 134 can be formed. The encapsulation 124, the lead 128, the contact 130, and the trace 134 can be formed with a characteristic of being formed with the encapsulation 124 and the conductive frame 304 of FIG. 3 thereover being pressed in the pressing phase as previously described.
The lead 128, the contact 130, and the trace 134 do not have dents or marks characteristic from a mold chase downward force normally found during an injection molding process. The lead 128, the contact 130, and the trace 134 are completely over the encapsulation 124 and not within the encapsulation 124.
The encapsulation 124 can have removal characteristics resulting from the patterning process of forming the lead 128, the contact 130, and the trace 134 from the horizontal cover 306. For example, the removal characteristics can include an etched surface, chemical residue, or a chemically processed surface.
It has been discovered that the integrated circuit packaging system 100 improves reliability. The support terminal 126 is formed from the conductive frame 304, having the vertical pillar 235 integral with the horizontal cover 306. With the encapsulation 124 and the support terminal 126 pressed thereon, a robust structure is provided to reliably mount external systems thereover, thereby improving the reliability.
It has also been discovered that the integrated circuit packaging system 100 provides an interconnection structure with reduced resistance. The support terminal 126, having the vertical pillar 235 integrated with the lead 128, the contact 130, and the trace 134, provides the interconnection structure with the resistance reduced.
Referring now to FIG. 6, therein is shown a top view of an integrated circuit packaging system 600 in a second embodiment of the present invention.

For example, the contact 630 can be a lead, a contact pad, or an electrical contact. Also for example, the contact 630 can be a redistributed lead.
The contact 630 can be formed in an area array adjacent to and between a number of the lead 628. The contact 630 can be connected to the lead 628.
For illustrative purposes, the contact 630 is shown in a full area array, although the contact 630 can be formed in a different configuration. For example, the contact 630 can be formed in a peripheral array adjacent to the lead 628.

The support terminal 626 can include a trace 634, defined as an electrical connection between the lead 628 and the contact 630. For example, the trace 634 can be a signal trace or a wire.
The trace 634 can be formed in different configurations. For example, the trace 634 can be formed with different lengths. A length of the trace 634 can be predetermined based on locations of the lead 628 and the contact 630, a distance between the lead 628 and the contact 630, a routing area that is used to form the trace 634, or a combination thereof.
The lead 628 can be formed in a row. For illustrative purposes, the lead 628 is shown in two rows along non-horizontal sides 644 of the encapsulation 624, although the lead 628 can be formed in a different configuration. For example, the lead 628 can be formed in four rows along the non-horizontal sides 644.
The lead 628 can be formed at the non-horizontal sides 644. The lead 628 can be formed with a side at the non-horizontal sides 644 and an opposite side connected to the trace 634.
