ST Microsystems is a software and VLSI design training center located in the IT-zone at Sitapura industrial area, Jaipur. It was established in 2001 and is the first VLSI design center in Rajasthan in private sector. The company has registered its presence in training sector through its high quality and expert training in emerging technologies. Keeping in view the importance that IT has gained in recent years and small number of institutes providing the industry level training in the area, ST Microsystems provides training in major key areas like VLSI, software design and development, embedded systems, SAP etc.

History of electronic circuit
Upto the 60’s the electronic circuit were bulky and slow . At that time , electronic circuit consisted of various discrete component like bipolar junction transistor (BJT),resistance , capacitance etc , to make the inter connection between these discrete component use copper wire . These kind of circuit known as “Discrete circuit”.These circuit consist very less component occupied very large space

Integrated Circuits(ICs)
What is Integrated Circuit?
Integrated Circuits contains several transistors fabricated on a single chip.

Ic development
•“Jack kilby” the person who develop first integrated circuit ,he is known as the father of ic.•This integrated circuit consist one resistor and one capacitor.•Germanium was used to make first ic.•In 1947 Schokly and barlin invented bipolar junction transistor and ic,s were formed using BJT.In 1960 mos invented and ic formed by using MOS

SSI (small-scale integration): Up to 100 electronic components per chip
MSI (medium-scale integration): From 100 to 3,000 electronic components per chip
LSI (large-scale integration): From 3,000 to 100,000 electronic components per chip
VLSI (very large-scale integration): From 100,000 to 1,000,000 electronic components per chip
ULSI (ultra large-scale integration): More than 1 million electronic components per chip

Moore’s Law• In 1965, Gordon Moore predicted that
the number of transistors that can be integrated on a die would double every 18 to 14 months• i.e., grow exponentially with time
• Amazing visionary – million transistor/chip barrier was crossed in the 1980’s.– 2300 transistors, 1 MHz clock (Intel
4004) - 1971– 42 Million, 2 GHz clock (Intel P4) -
2001– 140 Million transistor (HP PA-8500)

VLSI is an implementation technology for electronic circuitry - analogue or digital
It is concerned with forming a pattern of interconnected switches and gates on the surface of a crystal of semiconductor
Microprocessors personal computers microcontrollers
Memory - DRAM / SRAM Special Purpose Processors - ASICS (CD players, DSP
applications) Optical Switches Has made highly sophisticated control systems mass-
producable and therefore cheap
