VLSI Technology

VLSI Technology. Instructor: Dr. Nandita Dasgupta, Department of Electrical Engineering, IIT Madras. VLSI (Very Large Scale Integration or Very Large Scale Integrated Circuits) is the process of creating an integrated circuit (IC) by combining hundreds of thousands of transistors or devices into a single chip. This course covers lessons in bipolar junction transistor fabrication, crystal structure, crystal growth, epitaxy, oxidation, diffusion, lithography, etching, metallization, bipolar junction transistor, MOSFET, CMOS and BiCMOS technology.
