Patent number: 11387221Abstract: At least one array of LEDs (e.g., in a flip chip configuration) is supported by a substrate having a light extraction surface overlaid with at least one lumiphoric material. Light segregation elements registered with gaps between LEDs are configured to reduce interaction between emissions of different LEDs and/or lumiphoric material regions to reduce scattering and/or optical crosstalk, thereby preserving pixel-like resolution of the resulting emissions. Light segregation elements may be formed by mechanical sawing or etching to define grooves or recesses in a substrate, and filling the grooves or recesses with light-reflective or light-absorptive material. Light segregation elements external to a substrate may be defined by photolithographic patterning and etching of a sacrificial material, and/or by 3D printing.Type: GrantFiled: November 17, 2020Date of Patent: July 12, 2022Assignee: CREELED, INC.Inventors: John Edmond, Matthew Donofrio, Jesse Reiherzer, Peter Scott Andrews, Joseph G.

Patent number: 11309348Abstract: The present disclosure relates to a CMOS image sensor having a doped isolation structure separating a photodiode and a pixel device, and an associated method of formation. In some embodiments, the CMOS image sensor has a doped isolation structure separating a photodiode and a pixel device. The photodiode is arranged within the substrate away from a front-side of the substrate. A pixel device is disposed at the front-side of the substrate overlying the photodiode and is separated from the photodiode by the doped isolation structure. Comparing to previous image sensor designs, where an upper portion of the photodiode is commonly arranged at a top surface of a front-side of the substrate, now the photodiode is arranged away from the top surface and leaves more room for pixel devices. Thus, a larger pixel device can be arranged in the sensing pixel, and short channel effect and noise level can be improved.Type: GrantFiled: September 11, 2019Date of Patent: April 19, 2022Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Seiji Takahashi, Chen-Jong Wang, Dun-Nian Yaung, Jhy-Jyi Sze, Yimin Huang
