Description:
CROSS-REFERENCE TO THE RELATED APPLICATION 
     This application is based on and claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2019-0166604, filed on Dec. 13, 2019, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety. 
     BACKGROUND 
     1. Field 
     Embodiments of the disclosure relate to a process apparatus including a noncontact thermo-sensor and a method of adjusting a temperature in real time in performing a process. 
     2. Description of Related Art 
     In a semiconductor manufacturing process, a method of heating a workpiece for a short time is being widely used for increasing productivity. For example, technology for directly irradiating light onto a workpiece by using a heating lamp to heat the workpiece for a short time is being used. Also, since a process is very precisely performed, a temperature of a workpiece should be very accurately measured. In the related art, the temperature of the workpiece is measured by directly contacting a backside of the workpiece. However, since a front side of the workpiece is heated by light, a difference between a temporal temperature and a spatial temperature is large, and due to this, it is difficult to use a process of measuring a temperature of a backside of the workpiece. 
     However, related art is unable to measure a temperature by directly contacting the front side of the workpiece because a thermo-sensor is exposed to light. Therefore, in a process apparatus and a process of heating a workpiece by using a heating lamp, a temperature of a workpiece should be measured in real time by using a noncontact thermo-sensor such as a pyrometer. However, in a case which measures the temperature of the workpiece by using the noncontact thermo-sensor, a difference between a real temperature of the workpiece and a temperature measured by the noncontact thermo-sensor may be large due to the physical characteristic and optical characteristic of a surface of the workpiece, various influences caused by a heating lamp, process environments, etc. Particularly, when a wavelength band of light irradiated by the heating lamp overlaps a wavelength band of light received by the thermo-sensor for measuring a temperature, the reliability of measured temperature information is largely reduced.

     DETAILED DESCRIPTION 
     Recently, semiconductor manufacturing processes are being performed in a progressively lowered temperature area. Particularly, like a gas assisted bonder, processes performed within a relatively low temperature range are increasing. Silicon or silicon base materials widely used in a semiconductor process are weak in irradiation of wavelengths of 5 μm or less, and due to this, it is difficult to accurately measure a relatively low temperature of 300° C. or less. Therefore, receiving of light having a wavelength of 5 μm or more is needed for accurately measuring a relatively low process temperature of 300° C. or less. As described above, in a process of heating a workpiece for a short time, the process is unable to measure a temperature of the workpiece by using a contact thermo-sensor. That is, in an apparatus and process of heating a workpiece with light, a temperature should be measured for a short time by using a noncontact thermo-sensor. Also, as described above, light having a wavelength of 5 μm or more should be received for accurately measuring a temperature of 300° C. or less. However, a plate including a generally used quartz material blocks most of light having a wavelength of 5 μm or more. In various embodiments of the disclosure, certain light does not pass through a plate including a quartz material while using a noncontact thermo-sensor, and therefore, a method and apparatus of receiving light having a wavelength of 5 μm or more to accurately measure a temperature of 300° C. or less are provided. 
       FIG. 1A  is a side cross-sectional view schematically illustrating a process apparatus  100 A according to an embodiment of the disclosure, and  FIG. 1B  is an enlarged view of a region A. 
     Referring to  FIGS. 1A and 1B , the process apparatus  100 A according to an embodiment of the disclosure may include a process chamber  10 , a heating module  20 A, a supporter  50 , and a controller  60 . 
     The process chamber  10  may provide a process space PS between the heating module  20 A, disposed at an upper portion of the process chamber  10 , and the supporter  50 , disposed at a lower portion of the process chamber  10 , for performing a process. For example, the process chamber  10  may include stainless steel. 
     The heating module  20 A may be disposed at the upper portion of the process chamber  10  to heat a plurality of workpieces  71  and  72  and to measure temperatures of the workpieces  71  and  72 . 
     The heating module  20 A may include a housing  21 , a plurality of the heating lamp  23 , a temperature sensor  30 , and a blocking plate  40 . 
     The housing  21  may provide a main body which is coupled to the plurality of the heating lamp  23  and the temperature sensor  30 . The housing  21  may include stainless steel. 
     The plurality of the heating lamp  23  may generate light to heat the plurality of workpieces  71  and  72 . For example, the plurality of the heating lamp  23  may include a tungsten halogen lamp, a xenon lamp, a flash lamp, or other various lamps. The plurality of the heating lamp  23  may generate light having various wavelengths to irradiate the light onto the plurality of workpieces  71  and  72 . For example, the plurality of the heating lamp  23  may generate light having a wavelength of 1 μm or less and 5 μm or more or light having various wavelengths. The plurality of the heating lamp  23  may be disposed to be vertical to a surface of the supporter  50 . Therefore, the plurality of the heating lamp  23  may irradiate light onto a top surface of the supporter  50  and top surfaces of the plurality of workpieces  71  and  72  in a vertical direction. When light is irradiated onto the plurality of workpieces  71  and  72 , light energy applied to a unit area may be highest. Accordingly, light irradiated by the plurality of the heating lamp  23  may efficiently heat the plurality of workpieces  71  and  72 . 
     The temperature sensor  30  may include a light path  31 , a filter  33 , and a thermo-sensor  35 . 
     The light path  31  may provide a path through which light (a radiant wave) having temperature information is transferred from the plurality of workpieces  71  and  72  to the thermo-sensor  35 . The light path  31  may have a pipe or cylindrical shape that is an empty space. The light path  31  may be disposed to be vertical to the surface of the supporter  50 . Therefore, the light path  31  may collect light irradiated or radiated in a vertical direction from the supporter  50  and the plurality of workpieces  71  and  72  and may transfer and provide the collected light to the thermo-sensor  35 . When the light path  31  is vertical to the plurality of workpieces  71  and  72 , the thermo-sensor  35  may be disposed at a shortest distance from the plurality of workpieces  71  and  72 . Accordingly, the loss of temperature information based on a path may be minimized, and the thermo-sensor  35  may very accurately measure substantial temperatures of the plurality of workpieces  71  and  72 . 
     The filter  33  may block light having a relatively short wavelength of less than 5 μm and may transmit light having a relatively long wavelength of 5 μm or more. As described above, temperature information about a temperature of 300° C. or less may be sufficiently transferred based on light having a relatively long wavelength of 5 μm or more. Light having a relatively short wavelength of less than 5 μm may act as noise and may be less useful to measure temperature information about a temperature of 300° C. or less. Therefore, the process apparatus  100 A according to the disclosure may be very useful for a process of processing the plurality of workpieces  71  and  72  at a temperature of 300° C. or less. The filter  33  may include germanium (Ge) or a compound of germanium base. The filter  33  may be disposed in the light path  31  and may be apart from the process space PS and the blocking plate  40 . Since the filter  33  is apart from the process space PS, penetration of pollutants through the process space PS may be prevented. The filter  33  may have a mesh shape. The filter  33  may include a relatively narrow bottom surface and a relatively wide top surface. In a perspective view, the filter  33  may have a truncated cone shape. In a top view or a bottom view, the filter  33  may have a circular plate shape. A sealant may be disposed between the filter  33  and the housing  21 . 
     The thermo-sensor  35  may include a noncontact thermo-sensor such as a pyrometer or an infrared (IR) sensor. The thermo-sensor  35  may analyze light transferred and provided from the plurality of workpieces  71  and  72  to measure temperatures of the workpieces  71  and  72 . Particularly, the thermo-sensor  35  may analyze light information having a wavelength of 5 μm or more to provide the controller  60  with temperature information Temp 1  about the plurality of workpieces  71  and  72 . 
     The blocking plate  40  may be disposed at a whole lower portion of the heating module  20 A. The blocking plate  40  may spatially separate the plurality of the heating lamp  23  from the process space PS. Therefore, the blocking plate  40  may prevent the plurality of the heating lamp  23  from being polluted by pollutants which occur in the process space PS. The blocking plate  40  may include quartz. The blocking plate  40  may include a window W which opens a lower area of the temperature sensor  30 . Therefore, the temperature sensor  30  may be exposed at the process space PS, and the light path  31  of the temperature sensor  30  may be spatially connected to the process space PS. 
     The supporter  50  may support the plurality of workpieces  71  and  72 . The supporter  50  may include a supporting plate  51 , a heater  53 , and a cooler  55 , and the heater  53  and the cooler  55  may be embedded into the supporting plate  51 . The heater  53  may include a heating coil and may directly heat the plurality of workpieces  71  and  72  placed on the supporting plate  51 . The cooler  55  may circulate a refrigerant such as water through a plurality of cooling holes H provided therein to cool the supporting plate  51 . A temperature of the supporting plate  51  may be maintained to be constant by operations of the heater  53  and the cooler  55 . 
     The controller  60  may receive the temperature information Temp  1  measured from the thermo-sensor  35  and may transmit a heating command Heat to the plurality of the heating lamp  23 . The controller  60  may analyze the temperature information Temp 1  and may transmit, to each of the the heating lamp  23 , the heating command Heat for individually turning on/off the the heating lamp  23  or adjusting a heating power of each of the the heating lamp  23 . 
     The plurality of workpieces  71  and  72  may include a wafer and/or a plurality of bonding chips. For example, the workpiece  71  may include a wafer, and the plurality of workpieces  72  may include a plurality of bonding chips. For example, a die bonding process or a chip bonding process of bonding the plurality of bonding chips on the wafer may be performed in the process apparatus  100 A according to the disclosure. In an embodiment of the disclosure, in a case where a plurality of processes (for example, a deposition process, an etching process, an implant process, etc.) of directly processing the wafer in the process apparatus  100 A are performed, the workpiece  72  including the plurality of bonding chips may be omitted. 
       FIG. 2A  is a side cross-sectional view illustrating a process apparatus  100 B according to an embodiment of the disclosure, and  FIG. 2B  is an enlarged view of a region A. Referring to  FIGS. 2A and 2B , the process apparatus  100 B according to an embodiment of the disclosure may include a process chamber  10 , a heating module  20 B, a supporter  50 , and a controller  60 . The heating module  20 B may include a housing  21 , a plurality of the heating lamp  23  disposed in the housing  21 , a temperature sensor  30 , and a blocking plate  40  disposed under the housing  21 . The temperature sensor  30  may include a light path  31 , a filter  33 , a thermo-sensor  35 , and a blocking block  37 . 
     The blocking block  37  may be disposed in a lower area of the light path  31  of the temperature sensor  30 . The blocking block  37  may spatially separate the process space PS from the light path  31 , the filter  33 , and the thermo-sensor  35 . Therefore, the blocking block  37  may prevent pollutants, occurring in the process space PS, from polluting the light path  31  and the filter  33 . The blocking block  37  may transmit light having a relatively long wavelength of 5 μm or more. A portion of light having a wavelength of less than 5 μm may pass through the blocking block  37 . The blocking block  37  may include zinc selenide (ZnSe). A lower end of the blocking block  37  may be disposed at a level which is higher than a bottom surface of the blocking plate  40 . The blocking block  37  may horizontally and partially overlap a window W of the blocking plate  40 . In an embodiment, a bottom surface of the blocking block  37  and the bottom surface of the blocking plate  40  may be disposed at levels which are similar or substantially the same. The blocking block  37  may have a mesa shape. The blocking block  37  may have a relatively narrow bottom surface and a relatively wide top surface. In a perspective view, the blocking block  37  may have an inversely truncated cone shape. In a top view or a bottom view, the blocking block  37  may have a circular plate shape. A sealant may be disposed between the blocking block  37  and the blocking plate  40 .

The supporter  50  may include the supporting plate  51 , and the heater  53 , the cooler  55 , and the lower contact thermo-sensor  75  each embedded into the supporting plate  51 . The upper contact thermo-sensor  45  may directly contact the blocking plate  40  and may transfer temperature information Temp 2  about the blocking plate  40  to the controller  60 . The lower contact thermo-sensor  75  may directly contact the supporting plate  51  or a workpiece  71  and may transfer temperature information Temp 3  about the supporting plate  51  or the workpiece  71  to the controller  60 . 
       FIG. 8  is diagram describing an operation of measuring a temperature of a workpiece  71  by using a temperature sensor  30  of a heating module (e.g. one of heating modules  20 A-L) of each of a plurality of the process apparatus (e.g. process apparatuses  100 A-F) according to embodiments of the disclosure. 
     Referring to  FIG. 8 , the temperature sensor  30  may receive all of light Lt irradiated or radiated from the workpiece  71  and light Lb reflected from a surface of the workpiece  71 . For example, the light Lt irradiated or radiated from the workpiece  71  may include temperature information about the workpiece  71 . Light La irradiated from each of a plurality of the heating lamp  23  onto the workpiece  71  may be the light Lb reflected from the surface of the workpiece  71 , and thus, the light Lb reflected from the surface of the workpiece  71  may not include the temperature information about the workpiece  71 . That is, the light Lb reflected from the surface of the workpiece  71  may be a noise component. 
     Generally, the workpiece  71  may include silicon or a material of silicon base. Silicon may be low in irradiation rate of light having a wavelength of less than 5 μm and may be high in irradiation rate of light having a wavelength of 5 μm or more. The light Lt irradiated or radiated from the workpiece  71  may mainly include light having a wavelength of 5 μm or more. 
     The light La irradiated from each of the plurality of the heating lamp  23  may pass through the blocking plate  40  and may be provided to the workpiece  71 . As described above, the blocking plate  40  may include quartz, and thus, the light La irradiated onto the workpiece  71  may include only light which has a wavelength of less than 5 μm under a condition where light having a wavelength of 5 μm or more is blocked by the blocking plate  40 . That is, the light Lb reflected from the surface of the workpiece  71  may include light having a wavelength of less than 5 μm. Accordingly, accurate temperature information about the workpiece  71  may be obtained by removing a component of the light Lb reflected from the surface of the workpiece  71  from among the lights Lt and Lb received by the temperature sensor  30 . 
     The temperature sensor  30  according to various embodiments of the disclosure may include the filter  33  which blocks light having a wavelength of less than 5 μm and transmits light having a wavelength of 5 μm or more. Accordingly, the process apparatuses according to various embodiments of the disclosure may measure an accurate temperature of the workpiece  71 . 
     This will be described as expressed in the following Equation 1. 
         T (total)= T ( Lt )+ T ( Lb )   [Equation 1]
 
     Here, T(total) may denote total temperature information, T(Lt) may denote temperature information about the light Lt, and T(Lb) may denote temperature information about the light Lb. 
     In this case, most of the temperature information T(Lb) about the light Lb may be blocked by the filter  33 . That is, temperature information Temp 1  provided from the temperature sensor  30  to the controller  60  may be similar to the temperature information T(Lt) about the light Lt irradiated from the workpiece  71 . 
     The accurate temperature of the workpiece  71  may be obtained by removing a noise component from the temperature information Temp 1  provided from the temperature sensor  30  to the controller  60 . The noise component may include various components such as a temporal difference and temperature information about elements other than the workpiece  71 , in addition to the light Lb reflected from the workpiece  71 . In an embodiment, the accurate temperature of the workpiece  71  may be estimated by comparing the temperature information Temp 1 , provided from the temperature sensor  30  to the controller  60 , with temperature information Temp 2  about the blocking plate  40 . For example, referring to  FIGS. 5A and 5B , an accurate real temperature of the workpiece  71  may be estimated by comparing the temperature information Temp 1  with the temperature information Temp 2  about the blocking plate  40 . In an embodiment, the accurate temperature of the workpiece  71  may be estimated by comparing the temperature information Temp 1 , provided from the temperature sensor  30  to the controller  60 , with temperature information Temp 3  about the supporting plate  51  or a backside of the workpiece  71 . For example, referring to  FIG. 6 , an accurate real temperature of the workpiece  71  may be estimated by comparing the temperature information Temp 1  with temperature information Temp 3  about the supporting plate  51  or the backside of the workpiece  71 . 
     The temperature information Temp 1  measured by the temperature sensor  30 , the temperature information Temp 2  about the blocking plate  40 , and the temperature information Temp 3  about the supporting plate  51  or the backside of the workpiece  71  may have various distributions such as the kind, material, process kind, process temperature, process pressure, and various process conditions of the workpiece  71 . Therefore, a process of estimating the accurate temperature of the workpiece  71  may include various processes on the basis of the obtained temperature information Temp 1 , Temp 2 , and Temp 3 , including processes other than the processes described above. 
     A process of performing a semiconductor manufacturing process will be described below by using the process apparatus (e.g. one of process apparatuses  100 A-F) according to various embodiments described in the disclosure. 
     First, the plurality of workpieces  71  and  72  may be provided on the supporter  50  of the process apparatus (e.g. one of process apparatuses  100 A-F). In Step  1 , the plurality of workpieces  71  and  72  may be heated by the plurality of the heating lamp  23 . In Step 2 , temperatures of the plurality of workpieces  71  and  72  may be measured by using the thermo-sensor  35  of the temperature sensor  30 . In Step 3 , the measured temperature information Temp 1  may be provided to the controller  60 . In Step 4 , the controller  60  may analyze the temperature information Temp 1  to generate the heating command Heat for controlling the plurality of the heating lamp  23 . In Step 5 , the plurality of the heating lamp  23  may be independently controlled based on the heating command Heat in real time. When a process ends, the plurality of workpieces  71  and  72  may be unloaded to the outside of the process apparatus (e.g. one of process apparatuses  100 A-F). 
     The process apparatus according to the embodiments of the disclosure may receive light having a wavelength of 5 μm or more to measure a temperature of a workpiece. 
     The process apparatus according to the embodiments of the disclosure may include a plurality of noncontact thermo-sensors and a plurality of heating lamps disposed to be vertical to a top surface of the workpiece, and thus, may measure in real time an accurate temperature of the workpiece for a short time and may heat the workpiece.
