Patent number: 9209327Abstract: A pixel is formed in a semiconductor substrate (S) with a plane surface for use in a photodetector. It comprises an active region for converting incident light (In) into charge carriers, photogates (PGL, PGM, PGR) for generating a lateral electric potential (?(x)) across the active region, and an integration gate (IG) for storing charge carriers generated in the active region and a dump site (Ddiff). The pixel further comprises separation-enhancing means (SL) for additionally enhancing charge separation in the active region and charge transport from the active region to the integration gate (IG). The separation-enhancing means (SL) are for instance a shield layer designed such that for a given lateral electric potential (?(x)), the incident light (In) does not impinge on the section from which the charge carriers would not be transported to the integration gate (IG).Type: GrantFiled: January 22, 2014Date of Patent: December 8, 2015Assignee: Heptagon Micro Optics Pte. Ltd.Inventors: Simon Neukom, Michael Lehmann, Rolf Kaufmann, Thierry Oggier

Patent number: 7973841Abstract: A photo sensor exhibiting low noise, low smear, low dark current, high dynamic range and global shutter functionality consists either of a pinned (or buried) photodiode or a photo-sensitive charge-coupled device, each with associated transfer gate, a sub-linear element, a shutter transistor, a reset circuit and a read-out circuit. Using two output paths global shutter and high speed operation are possible for the linear and the sub-linear output of the sensor. Because of its compact size, the photo sensor can be employed in one- and two-dimensional image sensors, fabricated with industry-standard CMOS and CCD technologies.Type: GrantFiled: October 14, 2008Date of Patent: July 5, 2011Assignee: CSEM Centre Suisse d'Electronique et de Microtechnique SA - Recherche et DéveloppmentInventor: Simon Neukom
