MEMS Fabrication I : Process Flows and Bulk "Bulk Micromachining of Silicon," pp. 2 Complementarymetal-oxide-semiconductorcircuitpro¬ cess (1980stechnology) 87 3. ” Variability Still, the semiconductor manufacturing world has little choice but to move in this direction. Get this from a library! Process engineering analysis in semiconductor device fabrication. In order to compete in this industry, most semiconductor and semiconductor manufacturing equipment companies must export. Electronic packaging provides the in-terconnection from the IC to the printed circuit board (PCB). Semiconductor device fabrication is the process used to create the integrated circuits that are present in everyday electrical and electronic devices.
