5-inch silicon wafer MEMS devices, integrated circuits,dedicated substrates for discrete devices
Overview
Although silicon crystals may look metallic, they are not entirely metals. Due to the "free electrons" that move easily between atoms, metals are good conductors of electricity, and electricity is the movement of electrons. A pure silicon crystal, on the other hand, is nearly an insulator; allowing very little electricity to pass through it. However, this can be changed through a process called doping.
A silicon wafer is a material essential for manufacturing
semiconductors, which are found in all kinds of electronic devices
that enrich our lives. Few of us have a chance to encounter an
actual silicon wafer in daily life.
