Invisage Holds Promise for Machine Vision

Test & Measurement World published an article about Invisage QuantumFilm with QuantumShutter sensor. The article seems to be based on an interview with Michael Hepp, InVisage’s director of marketing. Few advantages for machine vision market are presented:

  1. Adjustable bandgap of QuantumFilm tunes the sensitivity for specific wavelength range
  2. QuantumShutter (a nice word for global shutter) eliminates rolling shutter artifacts
  3. Improved QE in range of 80 to 90%
  4. Process is simpler than BSI

Hepp said that the QuantumFilm sensors designed for camera phones will have a 1.4um pixel size, and next-generation devices are planned at 1.1um. Invisage's 1.1um pixels can use a 110nm process. "In a 1.4-micron pixel, we can achieve a 12,000-electron well," says Hepp.

TSMC is expected to sample chips made with the process this summer, said Hepp.
