Semiconductors : The Silicon Chip
Beginning of paper
Silicon is the raw material most often used in integrated circuit (IC)
fabrication. It is the second most abundant substance on the earth. It is
extracted from rocks and common beach sand and put through an exhaustive
purification process. In this form, silicon is the purist industrial
substance ....
Middle of paper
.... It is
used for diodes, transistors, integrated circuits, memories, infrared
detection and lenses, light-emitting diodes (LED), photosensors, strain
gages, solar cells, charge transfer devices, radiation detectors and a
variety of other devices. Silicon belongs to the group IV in the periodic
table. It is a grey brittle material with a diamond cubic structure.
Silicon is conventionally doped with Phosphorus, Arsenic and Antimony and
Boron, Aluminum, and Gallium acceptors. The energy gap ....
