IC chips used in computers are usually made of ____________.
IC chips used in computers are usually made of ____________.
The correct option is B Silicon
IC chips used in
computers are usually made of Silicon.
Mono-crystal silicon
wafers (or for special applications, silicon on sapphire or gallium arsenide
wafers) are used as the substrate. Photolithography is used to mark different
areas of the substrate to be doped or to have polysilicon, insulators or metal
(typically aluminium or copper) tracks deposited on them.
So in short, silicon is a
highly pure, easy to use, and cheap semiconductor, perfect for the now huge
computer chip industry. Answer 5: Silicon is used because it can be used as
either an insulator (doesn't allow electricity to flow) or a semiconductor
(allows a little flow of electricity).
The silicon chip was
invented in 1961 by two American electrical engineers, Jack Kilby and Robert
Noyce. Their creation revolutionized and miniaturized technology and paved the
way for the development of the modern computer.
Silicon is a chemical
element with symbol Si and atomic number 14. It is a hard and brittle
crystalline solid with a blue-grey metallic lustre; and it is a tetravalent
metalloid and semiconductor. It is a member of group 14 in the periodic table:
carbon is above it; and germanium, tin, and lead are below it.
