Question

Integrated Circuit Chip in computer is made of_______.
1. Cromium
2. Iron oxide
3. Silicon
4. Silica

Answer 1

Correct Answer - Option 3 : Silicon

The correct answer is Silicon.

• The integrated Circuit Chip in the computer is made of Silicon.
• The full form of IC Chips is integrated circuit chips. It is made up of semiconductor material which is normally silicon.
• An integrated circuit (ICs) is an electronic device comprising numerous functional elements such as transistors, resistors, condensers, etc.
• In the manufacturing process of IC, electronic circuits with components such as transistors are formed on the surface of a silicon crystal wafer.
• Silicon-made computer integrated chip examples are Microcontrollers, microprocessors, and FPGAs, etc.

Metal	Description/Uses
Chromium	Passivation with hexavalent chromium is used in electrical and electronic equipment, particularly for coating electro-galvanized steel and aluminum.
Iron oxide	Iron oxides are widespread in nature and play an important role in many geological and biological processes. They are used as iron ores, pigments, catalysts, and in thermite, and occur in hemoglobin. Iron oxides are inexpensive and durable pigments in paints, coatings and coloured concretes.
Silica	Silicon dioxide or Sand or Silica and clay (aluminium silicate) are used to make concrete and cement.
