Semiconductors: Manufacture and Applications

Semiconductors are found in almost every electronic device in your home. The process to build one has many phases, including rigorous testing. The device is able to regulate the flow of energy, like an “on/off” switch. Creating the circuitry is done in steps, and requires advanced fabrication techniques like plasma-enhanced chemical vapor deposition. Here is a bit more information on how this process works.

Semiconductor Manufacture

Semiconductors need to have a circuit board mapped out, then circuitry applied. They are made of compacted silicon, which is then shaped and hardened before they are cut to size. The chips are often wafer thin, and the entire process can take up to eight weeks. This is all done at a nearly microscopic level due to the precision required. First, a kind of “map of circuitry” is drawn (or more accurately, printed) onto the surface of the board. Next, ion beam etching is used to apply the materials to the circuit board.

Throughout this process, hazardous materials are used to coat the device, including arsine and phosphorus. After manufacture, chips must be tested with an electronic tester. This devices presses tiny probes against the chip to determine if it transfers power properly.


Semiconductors are found in just about anything. They are the primary components in computers, but they are found in other electronic appliances as well. They are used to transfer power from one section of a device to another, like powering a computer processor.
