Integrated Circuit (IC), Design and Assembly

American Journal of Computer Science and Engineering Survey (AJCSES) is a peer review open access journal publishing the research in computer science and engineering survey. Below we have discussed about Integrated Circuits and designs.

Definition

An integrated circuit (IC) is a small semiconductor-based electronic device consisting of fabricated transistors, resistors and capacitors. Integrated circuits are the building blocks of most electronic devices and equipment.

An integrated circuit is also known as a chip or microchip.

An integrated circuit is built with the primary objective of embedding as many transistors as possible on a single semiconductor chip with numbers reaching in the billions as of 2012.

Terminology

An integrated circuit is defined as:

A circuit in which all or some of the circuit elements are inseparably associated and electrically interconnected so that it is considered to be indivisible for the purposes of construction and commerce.

Circuits meeting this definition can be constructed using many different technologies, including thin-film transistors, thick-film technologies, or hybrid integrated circuits. However, in general usage integrated circuit has come to refer to the single-piece circuit construction originally known as a monolithic integrated circuit.

Design

The cost of designing and developing a complex integrated circuit is quite high, normally in the multiple tens of millions of dollars. Therefore, it only makes economic sense to produce integrated circuit products with high production volume, so the non-recurring engineering (NRE) costs are spread across typically millions of production units.

Modern semiconductor chips have billions of components, and are too complex to be designed by hand. Software tools to help the designer are essential. Electronic Design Automation (EDA), also referred to as Electronic Computer-Aided Design (ECAD) is a category of software tools for designing electronic systems, including integrated circuits. The tools work together in a design flow that engineers use to design and analyze entire semiconductor chips.

According to their design assembly, integrated circuits have undergone several generations of advancements and developments such as:

• Small Scale Integration (SSI): Ten to hundreds of transistors per chip
• Medium Scale Integration (MSI): Hundreds to thousands of transistors per chip
• Large Scale Integration (LSI): Thousands to several hundred thousand transistors per chip
• Very Large Scale Integration (VLSI): Up to 1 million transistors per chip
• Ultra Large Scale Integration (ULSI): This represents a modern IC with millions and billions of transistors per chip

An IC can be further classified as being digital, analog or a combination of both. The most common example of a modern IC is the computer processor, which consists of billions of fabricated transistors, logic gates and other digital circuitry.
