US11837670B2	Semiconductor devices with single-photon avalanche diodes, light scattering structures, and multiple deep trench isolation structures An imaging device may include single-photon avalanche diodes (SPADs). To improve the sensitivity and signal-to-noise ratio of the SPADs, light scattering structures may be formed in the semiconductor substrate to increase the path length of incident light through the semiconductor substrate. To mitigate crosstalk, multiple rings of isolation structures may be formed around the SPAD. An outer deep trench isolation structure may include a metal filler such as tungsten and may be configured to absorb light. The outer deep trench isolation structure therefore prevents crosstalk between adjacent SPADs. Additionally, one or more inner deep trench isolation structures may be included. The inner deep trench isolation structures may include a low-index filler to reflect light and keep incident light in the active area of the SPAD.
US11837666B2	Semiconductor device A transistor that is to be provided has such a structure that a source electrode layer and a drain electrode layer between which a channel formation region is sandwiched has regions projecting in a channel length direction at lower end portions, and an insulating layer is provided, in addition to a gate insulating layer, between the source and drain electrode layers and a gate electrode layer. In the transistor, the width of the source and drain electrode layers is smaller than that of an oxide semiconductor layer in the channel width direction, so that an area where the gate electrode layer overlaps with the source and drain electrode layers can be made small. Further, the source and drain electrode layers have regions projecting in the channel length direction at lower end portions.
