Patent number: 11942496Abstract: A digital image sensor package includes an image sensor substrate and a glass covering. The image sensor substrate carries photodiodes. The glass covering has a bottom surface, a top surface opposite the bottom surface, and a sidewall delimiting a perimeter edge of the glass covering. The glass covering overlies the photodiodes. A surface area of the top surface of the glass covering is greater than a surface area of the bottom surface of the glass covering such that the sidewall is anti-perpendicular to the top and bottom surfaces of the glass.Type: GrantFiled: May 21, 2021Date of Patent: March 26, 2024Assignee: STMicroelectronics Pte LtdInventors: Laurent Herard, David Gani

Patent number: 11502029Abstract: The present disclosure provides devices and methods in which a semiconductor chip has a reduced size and thickness. The device is manufactured by utilizing a sacrificial or dummy silicon wafer. A recess is formed in the dummy silicon wafer where the semiconductor chip is mounted in the recess. The space between the dummy silicon wafer and the chip is filled with underfill material. The dummy silicon wafer and the backside of the chip are etched using any suitable etching process until the dummy silicon wafer is removed, and the thickness of the chip is reduced. With this process, the overall thickness of the semiconductor chip can be thinned down to less than 50 ?m in some embodiments. The ultra-thin semiconductor chip can be incorporated in manufacturing flexible/rollable display panels, foldable mobile devices, wearable displays, or any other electrical or electronic devices.Type: GrantFiled: July 13, 2020Date of Patent: November 15, 2022Assignees: STMICROELECTRONICS PTE LTD, STMICROELECTRONICS (ROUSSET) SASInventors: Laurent Herard, David Parker, David Gani
