ON Semi and Teledyne Designed 16MP MCT Sensor

Business Wire: ON Semiconductor collaborated with Teledyne Imaging Sensors to manufacture an Extremely Large Stitched Read Out Integrated Circuit (ELS ROIC) for astronomy.

The 16MP H4RG-15 consists of Teledyne’s HgCdTe detector material hybridized to a CMOS readout circuit. It is said to be the largest sensor ever produced for IR astronomy. The H4RG-15 63 mm x 63 mm stitched CMOS ROIC uses ON Semiconductor’s proprietary 180nm process. The ROIC is so large that only four die fit onto a 200 mm wafer.

The H4RG-15 ROICs were manufactured at ON Semiconductor’s fab located in Gresham, Oregon. With this project, ON Semiconductor has demonstrated that it can successfully produce the H4RG-15 with the yield required for this next generation sensor.

The H4RG-15 sensor has been installed at the University of Hawaii’s observatory on Mauna Kea to confirm the performance of the sensor under telescope observing conditions. "The resolution with which images can be captured using this new sensor system represents a major step forward in the progression of IR astronomy," said Dr. Donald Hall of the Institute for Astronomy at the University of Hawaii, who is the principal investigator for the NSF-funded H4RG-15 development program.


  1. Is this CTIA based pixel or simply SF based pixel design??


  2. Looks like a CTIA pixel..

  3. SFD (Source Follower per Detector)
