  • CMOS wavefront sensors
    Patent number: 11804505
    Abstract: A Complementary Metal Oxide Semiconductor (CMOS) wavefront sensor including a sensor element having an array of photodiodes and a passivation layer covering the sensor element. The sensor further includes a binary lens formed in the passivation layer and arranged to focus incident light onto the sensor element.
    Type: Grant
    Filed: August 28, 2020
    Date of Patent: October 31, 2023
    Assignee: X-FAB SEMICONDUCTOR FOUNDRIES GMBH

  • Single photon avalanche diode devices
    Patent number: 11575061
    Abstract: A single photon avalanche diode (SPAD) device comprises: a silicon layer; an active region in said silicon layer for detecting incident light; and a blocking structure overlapping said active region for blocking incident light having a wavelength at least in the range of 200 nm to 400 nm, so that light having said wavelength can only be detected by said SPAD device when incident upon a region of said silicon layer outside of said active region.
    Type: Grant
