Difficulty: EasyIntegrated Circuits

Monolithic integrated circuits contain microscopic electronic components such as transistors, diodes, and resistors fabricated directly onto a single thin piece of semiconductor material. What is this semiconductor base commonly called?

  1. A
    Insulating ceramic substrate
  2. Silicon waferAnswer
  3. C
    Magnetic ferrite core
  4. D
    Bipolar junction terminal

Answer

Silicon wafer
A monolithic integrated circuit is produced by creating all necessary circuit elements—including transistors, diodes, and resistors—on a single thin slice of crystalline semiconductor material (most commonly silicon). In microelectronics manufacturing, this foundation slice is called a silicon wafer.

Step-by-Step Solution

1
Identify the structural foundation of a monolithic integrated circuit
Monolithic ICs are manufactured as a single, solid physical unit on a continuous semiconductor slice
The word 'monolithic' indicates that all circuit components share a single, unified semiconductor base rather than separate discrete parts
2
Apply standard electronics manufacturing terminology to the semiconductor base
A thin, polished slice of crystalline silicon used as the substrate is termed a wafer
Wafers provide the crystal foundation into which microscopic active and passive components are diffused, etched, and interconnected
