  • Patent number: 11922887
    Abstract: A display may include an array of pixels. Each pixel in the array includes an organic light-emitting diode coupled to associated thin-film transistors. The diode may be coupled to drive transistor circuitry, a data loading transistor, and emission transistors. The drive transistor circuitry may include at least two transistor portions connected in series. The data loading transistor has a drain region connected to a data line and a source region connected directly to the drive transistor circuitry. The data line may be connected to and overlap the drain region of the data loading transistor. The data line and the source region of the data loading transistor are non-overlapping to reduce row-to-row crosstalk.

  • Patent number: 11195763
    Abstract: In a method, a fin structure, in which first semiconductor layers and second semiconductor layers are alternately stacked, is formed. A sacrificial gate structure is formed over the fin structure. The first semiconductor layers are etched at a source/drain region of the fin structure, which is not covered by the sacrificial gate structure, thereby forming a first source/drain space in which the second semiconductor layers are exposed. A dielectric layer is formed at the first source/drain space, thereby covering the exposed second semiconductor layers. The dielectric layer and part of the second semiconductor layers are etched, thereby forming a second source/drain space. A source/drain epitaxial layer is formed in the second source/drain space. At least one of the second semiconductor layers is in contact with the source/drain epitaxial layer, and at least one of the second semiconductor layers is separated from the source/drain epitaxial layer.

  • Patent number: 11043423
    Abstract: A semiconductor structure includes a plurality of first semiconductor layers interleaved with a plurality of second semiconductor layers. The first and second semiconductor layers have different material compositions. A dummy gate stack is formed over an uppermost first semiconductor layer. A first etching process is performed to remove portions of the second semiconductor layer that are not disposed below the dummy gate stack, thereby forming a plurality of voids. The first etching process has an etching selectivity between the first semiconductor layer and the second semiconductor layer. Thereafter, a second etching process is performed to enlarge the voids.
