Abstract: A device includes a first semiconductor fin, a second semiconductor fin, a source/drain epitaxial structure, a semiconductive cap, and a contact. The first semiconductor fin and the second semiconductor fin are over a substrate. The source/drain epitaxial structure is connected to the first semiconductor fin and the second semiconductor fin. The source/drain epitaxial structure includes a first protruding portion and a second protruding portion aligned with the first semiconductor fin and the second semiconductor fin, respectively. The semiconductive cap is on and in contact with the first protruding portion and the second protruding portion. A top surface of the semiconductive cap is lower than a top surface of the first protruding portion of the source/drain epitaxial structure. The contact is electrically connected to the source/drain epitaxial structure and covers the semiconductive cap.

Abstract: An apparatus includes a six-axis correction stage, an auto-collimation measurement device, a light splitter, a telecentric image measurement device, and a controller. The six-axis correction stage carries a device under test; the auto-collimation measurement device is arranged above the six-axis correction stage along a measurement optical axis; the light splitter is arranged on the measurement optical axis and is interposed between the six-axis correction stage and the auto-collimation measurement device. A method controls the six-axis correction stage to correct rotation errors in at least two degrees of freedom of the device under test according to a measurement result of the auto-collimation measurement device, and controls the six-axis correction stage to correct translation and yaw errors in at least three degrees of freedom of the device under test according to a measurement result of the telecentric image measurement device by means of the controller.

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: An input module includes a knob, a first circuit board, an optical transmitter and an optical receiver. The knob has a peripheral surface. The optical transmitter is disposed on the first circuit board and faces the peripheral surface, wherein the optical transmitter is configured to emit a detecting light to the peripheral surface. The optical receiver is disposed on the first circuit board and configured to receive a reflected light of the detecting light reflected from the peripheral surface.

Abstract: In some embodiments, a stylus device includes two switch mechanisms, one disposed at the stylus tip portion and the other disposed at the stylus end portion. The stylus device also includes a wireless transceiver that allows the stylus device to communicate back to an electronic host device (e.g., an electronic tablet) in response to a user contacting the surface of a host device with the stylus tip portion or the stylus end portion. This enables, for example, a wide range of dual stylus device functions for electronic tablet applications. For example, the stylus device can be used to write and/or draw with the stylus tip portion and then can be flipped to the stylus end portion to erase as a user would generally do with a conventional pencil on paper. In another example, the stylus device can include a marker color tip on the stylus tip portion and a color blender on the stylus end portion.

Abstract: An assembled DIY floor comprises a floor unit having an approximate rectangular shape; an upper side of the floor unit being formed with a groove which also has an approximate rectangular shape; the groove serving for receiving a floor plate; the floor plate being adhered to the groove by using a sticky layer; an upper lateral side of the groove having a buckle for buckling the floor plate to the floor unit; an assembly portion installed around the floor unit; the assembly portion including a plurality of projections and a plurality of recesses. When assembling two floor units, the projections are buckled to the recesses so as to assembly two floor units. In assembly, two floor units are assembled; the projections of a floor unit are combined to the recesses of another floor unit; the floor plate being combined to the groove of the floor unit through the sticky layer; and the floor unit is adhered to ground.
