Both the Minuteman missile and Apollo program needed light-weight digital computer systems for his or her inertial steerage methods. Although the Apollo Guidance Computer led and motivated integrated-circuit technology, it was the Minuteman missile that compelled it into mass-manufacturing.

  • Integrated optical circuits are additionally being developed, utilizing the emerging area of physics generally known as photonics.
  • A problem most critical to analog IC design involves the variability of the individual units constructed on the semiconductor chip.
