Interconnect processes

What is the main role of the wiring inside an LSI?

  1. ATo electrically connect transistors to each other and to power and I/O terminals, carrying signals and power
  2. BTo emit light
  3. CTo store data long term
Show answer and explanation

Answer: A. To electrically connect transistors to each other and to power and I/O terminals, carrying signals and power

LSI wiring connects billions of transistors to each other and to power and terminals leading off the chip, carrying signals and power. It is built in many layers stacked above the transistors.

  • A. Correct. It connects devices to each other and to power and terminals.
  • B. Emitting light is the role of light-emitting devices.
  • C. Storing data is the role of memory cells.
