VLSI Certification Exam

What Is VLSI?

The method of integrating millions of MOS transistors onto a single chip is referred to as very large-scale integration (VLSI). When MOS integrated circuit chips became widely used in the 1970s, VLSI was born, allowing complex semiconductor and telecommunication technologies to be built. VLSI devices make up the microprocessor and memory. Most ICs could only perform a limited number of functions prior to the development of VLSI technology. A CPU, ROM, RAM, and other glue logic are examples of electronic circuits. IC designers can combine all of these functions into a single chip using VLSI.

The transistor was invented in the 1920s by a group of inventors who attempted to control current in solid-state diodes and convert them to triodes. After WWII, when silicon and germanium crystals were used as radar detectors, fabrication and theory improved. Scientists who had previously worked on radar have returned to the creation of solid-state devices. The field of electronics changed from vacuum tubes to solid-state devices with the creation of the first transistor at Bell Labs in 1947.

The first commercial MOS integrated circuit was released in 1964 by General Microelectronics. MOS integrated circuit technology, which was developed in the early 1970s, permitted the integration of more than 10,000 transistors on a single chip. With tens of thousands of MOS transistors on a single chip, VLSI became a reality in the 1970s and 1980s (later hundreds of thousands, then millions, and now billions).

Two transistors were present in the early semiconductor chips. More transistors were added in subsequent breakthroughs, resulting in the integration of more discrete functions or systems throughout time. The original integrated circuits contained only a few elements, possibly as many as ten diodes, transistors, resistors, and capacitors, allowing one or more logic gates to be built on a single chip. Improvements in methodology led to devices having hundreds of logic gates, which are today referred as as medium-scale integration (MSI) (MSI). Large-scale integration resulted from further enhancements (LSI)
