This course provides an introduction to the design and implementation of VLSI circuits for complex digital systems. It aims to convey advanced concepts of circuit design and analysis for digital LSI and VLSI systems in CMOS technology. This course emphasizes analysis, design, layout, and optimization of handcrafted circuits. Design and analysis of various static and dynamic, combinational and sequential CMOS circuit styles will be introduced. After understanding basic circuit design issues, participants will delve into subsystem design of adders, multipliers, and memory.
If you are interested in becoming an expert in the field of fabrication of ICs, adders, multipliers, then you are at the right place. Technofist is providing VLSI courses for engineering students. Technofist offers a great chance to work in different aspects of VLSI. As an E & C engineer, you will be getting a chance to work as part of a team on multidisciplinary projects where Verilog coding is done. By the end of the course, our students develop an advanced understanding of the theory as well as the practical aspects of the technology.

VLSI
The development of microelectronics spans a time which is even lesser than the average life expectancy of a human, and yet it has seen as many as four generations. Early 60s saw the low density fabrication processes classified under Small Scale Integration (SSI) in which transistor count was limited to about 10. This rapidly gave way to Medium Scale Integration in the late 60s when around 100 transistors could be placed on a single chip.
It was the time when the cost of research began to decline and private firms started entering the competition in contrast to the earlier years where the main burden was borne by the military. Transistor-Transistor logic (TTL) offering higher integration densities outlasted other IC families like ECL and became the basis of the first integrated circuit revolution. It was the production of this family that gave impetus to semiconductor giants like Texas Instruments, Fairchild, and National Semiconductors. Early seventies marked the growth of transistor count to about 1000 per chip called the Large Scale Integration.
By mid-eighties, the transistor count on a single chip had already exceeded 1000 and hence came the age of Very Large Scale Integration or VLSI. Though many improvements have been made and the transistor count is still rising, further names of generations like ULSI are generally avoided. It was during this time when TTL lost the battle to the MOS family owing to the same problems that had pushed vacuum tubes into negligence, power dissipation and the limit it imposed on the number of gates that could be placed on a single die.
The second age of Integrated Circuits revolution started with the introduction of the first microprocessor, the 4004 by Intel in 1972 and the 8080 in 1974. Today many companies like Texas Instruments, Infineon, Alliance Semiconductor, Cadence, Synopsys, Celox Networks, Cisco, Micron Tech, National Semiconductors, ST Microelectronics, Qualcomm, Lucent, Mentor Graphics, Analog Devices, Intel, Philips, Motorola, and many other firms have been established and are dedicated to the various fields in “VLSI” like Programmable Logic Devices, Hardware Descriptive Languages, Design tools, Embedded Systems, etc.
Fabrication Process
Why polysilicon gate?
The most significant aspect of using polysilicon as the gate electrode is its ability to be used as a further mask to allow precise definition of source and drain regions. This is achieved with minimum gate to source/drain overlap, which leads to lower overlap capacitances and improved circuit performance.
Procedure:
A thick layer of oxide is grown on the wafer surface which is known as field oxide (FOX). It is much thicker than the gate oxide. It acts as a shield that protects the underlying substrate from impurities when other processes are being carried out on the wafer. Besides, it also aids in preventing conduction between unrelated transistor source/drains. In fact, the thick FOX can act as a gate oxide for a parasitic MOS transistor. The threshold voltage of this transistor is much higher than that of a regular transistor due to thick field oxide. The high threshold voltage is further ensured by introducing channel-stop diffusion underneath the field oxide, which raises the impurity concentration in the substrate
