What is Vlsi: Definition and 16 Discussions

Very large-scale integration (VLSI) is the process of creating an integrated circuit (IC) by combining millions of MOS transistors onto a single chip. VLSI began in the 1970s when MOS integrated circuit chips were widely adopted, enabling complex semiconductor and telecommunication technologies to be developed. The microprocessor and memory chips are VLSI devices. Before the introduction of VLSI technology, most ICs had a limited set of functions they could perform. An electronic circuit might consist of a CPU, ROM, RAM and other glue logic. VLSI lets IC designers add all of these into one chip.

    Why positive PR is the better than negative PR in VLSI

    As attached, I know basic concept between Positive and Negative PR But, I confirm this message; Negative resists were popular in the early history of integrated circuit processing, but positive resist gradually became more widely used since they offer better process controllability for small...

    Is the VLSI field oversaturated?

    I am trying to decide on my area specialization for graduate school. I really like VLSI design. However, I get the feeling that because VLSI jobs are not common in the defense industry, the field is very saturated with people who don't have other options for EE work in the US (non-US...
