Fabrication of the multi-PCR chamber with inner heat-sink materials using a micro-blaster etching technique

Abstract

In this paper, we propose a new design for a PCR (polymerase chain reaction) chamber with a temperature sensor under a top glass wafer and heaters on the bottom glass wafer. These chamber sensors are thermally isolated from the heater. The multi PCR chamber has an inner heat-sink material of etched silicon mass or glass mass using a micro-blaster. Then we will capture the image of the thermal mass temperature profile among the chambers by using the TIS (thermal imaging system). The performance of the inner heat-sink materials is analyzed during the PCR cycles and the thermal interference of the chamber, respectively.
