Question

What process is used in semiconductor industry to fabricate Integrated Circuits?

(a) Silicon wafer preparation

(b) Silicon planar process

(c) Epitaxial growth of silicon

(d) Photolithography process

This question was addressed to me in class test.

This intriguing question originated from Basic Planar Process in division IC Fabrication of Linear Integrated Circuits

Answer 1

Correct choice is (b) Silicon planar process

For a clear picture: The planar process (Silicon planar technology) in semiconductor industry built individual components. It is the primary process by which Integrated Circuits are built. The other processes are the different steps involved within the planar process.
