The Tradition of Sharing

Help your friends and juniors by posting answers to the questions that you know. Also post questions that are not available.

To start with, Sr2Jr’s first step is to reduce the expenses related to education. To achieve this goal Sr2Jr organized the textbook’s question and answers. Sr2Jr is community based and need your support to fill the question and answers. The question and answers posted will be available free of cost to all.

How does an integrated circuit differ from a transistor?



The transistor is made using semiconductor material with three layers. Two types of materials are used. They are P-type and N-type material. The transistor is constructed either by a slice of P-type material is sandwiched between two N-type materials, or a slice of N-type material is sandwiched between two P-type materials.

The first one is called an NPN transistor, and the second one is called a PNP transistor. The inner layer of the transistor is called the base; the other two layers are called the collector and emitter.

Integrated circutes are manufactured by fabricating the hundreds to millions of microscopic transistors. 

Integrated circutes are also called as chips. 

So, integrated circuit are nothing but hundreds to millions of microscopic transistors that are connected to each other.
