Abstract: A method for manufacturing a nanosheet semiconductor device includes forming a poly gate on a nanosheet stack which includes at least one first nanosheet and at least one second nanosheet alternating with the at least one first nanosheet; recessing the nanosheet stack to form a source/drain recess proximate to the poly gate; forming an inner spacer laterally covering the at least one first nanosheet; and selectively etching the at least one second nanosheet.

Abstract: Disclosed are calibration techniques that can be implemented by a device that conducts biological tests. In certain embodiments, the device for testing a biological specimen includes a receiving mechanism to receive a carrier, a camera module arranged to capture imagery of the carrier, and a processor. Some examples of the processor can detect a calibration mode trigger. In calibration mode, the processor can divide the captured imagery into segments and selectively perform one or more calibration procedures for each segment. Then, the processor records a calibration result for each segment.

Abstract: A method includes depositing a first semiconductor layer and a second semiconductor layer over a substrate; patterning the first semiconductor layer, the second semiconductor layer, and the substrate to form a first nanostructure, a second nanostructure, and a semiconductor fin; forming a recess in the first nanostructure and the second nanostructure, the recess exposing the semiconductor fin; epitaxially growing a first layer in the recess, a first portion of the first layer being disposed along a first sidewall of the first nanostructure, a second portion of the first layer being disposed along the semiconductor fin, the first portion of the first layer comprising two sidewalls extending toward a middle of the recess, the first portion of the first layer further comprising a first surface most distal from the first sidewall and directly interposed between the two sidewalls, the first portion being physically separated from the second portion; and epitaxially growing a second layer over the first portion of
