WebTemporary Bond. Four inch silicon wafers were bonded to thin (325 µm) fused silica using BCB as the adhesive. The silicon and silica wafers were cleaned using an ultrasonic SC1 bath, rinsed in DI water and spin dried. An adhesive promoter followed by BCB was spin coated on the silicon wafers. The wafers were soft baked for 20 minutes at 100°C. Semiconductor device fabrication is the process used to manufacture semiconductor devices, typically integrated circuits (ICs) such as computer processors, microcontrollers, and memory chips (such as NAND flash and DRAM) that are present in everyday electrical and electronic devices. It is a multiple-step photolithographic and physico-chemical process (with steps such as thermal ox…
