Which material is used to manufacture Computer Chips?

Correct option is D

Computer chips — including microprocessors, memory modules, and integrated circuits — are made using semiconductor materials, primarily silicon. Silicon is abundant, relatively inexpensive, and has ideal electrical properties that allow it to conduct electricity under certain conditions and insulate under others, making it perfect for creating logic circuits.

Important Key Points:

1. Semiconductors enable the construction of transistors, the fundamental building blocks of modern chips.
2. Silicon wafers are processed using photolithography and doping techniques to build integrated circuits.
3. The semiconductor industry is central to computing, telecommunications, and electronics.

Knowledge Booster:

• Silver: A good electrical conductor, but not used to build the chip itself — sometimes used in connectors or contacts.
• Iron: A metal, mainly used in hardware casings or magnetic storage but not suitable for chip fabrication.
• Gold: Excellent conductor, used in high-quality connectors and bonding wires, but not as the chip’s core material.
