Patent number: 9917118Abstract: The present invention is directed to photodiode arrays comprising a dielectric structure containing an array of face conductive areas (pads) and. Each photodiode is fully separated from each other. Every photodiode has a face electrode formed on sensitive side of the semiconductor substrate and an individual back electrode formed on the opposite side. The number of conductive areas on the dielectric structure is equal to number of photodiodes in the array. The photodiodes of the array are installed on the conductive areas so that their back electrodes have electrical contact with the corresponding conductive area. Each conductive area contains at least one individual conductive hole penetrating the dielectric package from the face side to the opposite side of the dielectric structure. The conductive holes going to backside of the dielectric structure are connected with the back conductive areas formed on back side of dielectric package.Type: GrantFiled: September 10, 2012Date of Patent: March 13, 2018Assignee: ZECOTEK IMAGING SYSTEMS PTE. LTD.Inventors: Ziraddin Yagub-Ogly Sadygov, Abdelmounaime Faouzi Zerrouk, Azar Sadygov, Azman Mohd Ariffin, Serge Khorev

Patent number: 9257588Abstract: The invention is directed to an avalanche photodiode containing a substrate and semiconductor layers with various electro-physical properties having common interfaces both between themselves and with the substrate. The avalanche photodiode may be characterized by the presence in the device of at least one matrix consisting of separate solid-state areas with enhanced conductivity surrounded by semiconductor material with the same type of conductivity. The solid-state areas are located between two additional semiconductor layers, which have higher conductivity in comparison to the semiconductor layers with which they have common interfaces. The solid-state areas are generally made of the same material as the semiconductor layers surrounding them but with conductivity type that is opposite with respect to them. The solid-state areas may be made of a semiconductor with a narrow forbidden zone with respect to the semiconductor layers with which they have common interfaces.Type: GrantFiled: May 30, 2014Date of Patent: February 9, 2016Assignee: Zecotek Imaging Systems Singapore Pte Ltd.Inventors: Ziraddin Yegub-Ogly Sadygov, Abdelmounaime Faouzi Zerrouk
