  • Publication number: 20240154043
    Abstract: A semiconductor device includes channel members vertically stacked, a gate structure wrapping around the channel members, a gate spacer disposed on sidewalls of the gate structure, an epitaxial feature abutting the channel members, and an inner spacer layer interposing the gate structure and the epitaxial feature. In a top view of the semiconductor device, the inner spacer layer has side portions in physical contact with the gate spacer and a middle portion stacked between the side portions. In a lengthwise direction of the channel members, the middle portion of the inner spacer layer is thicker than the side portions of the inner spacer layer.

  • Patent number: 11973077
    Abstract: A device includes a transistor, a backside via, and a pair of sidewall spacers. The transistor includes a gate structure, a channel layer surrounded by the gate structure, and a first source/drain structure and a second source/drain structure connected to the channel layer. The backside via is under and connected to the first source/drain structure and includes a first portion, a second portion between the first portion and the first source/drain structure, and a third portion tapering from the first portion to the second portion in a cross-sectional view. The pair of sidewall spacers are on opposite sidewalls of the second portion of the backside via but not on opposite sidewalls of the first portion of the backside via.

  • Publication number: 20240123151
    Abstract: An insertion device includes an upper casing, an insertion module and a lower casing. The insertion module is disposed in the upper casing, and includes a main body assembly, an insertion seat, a first elastic member, a retraction seat and a second elastic member. When the upper casing is depressed, the insertion seat is driven by the first elastic member to perform an automatic-insertion operation, such that limiting structure between the insertion seat and the retraction seat collapses upon the collapse of another limiting structure between the insertion seat and the main body assembly, and that the retraction seat is driven by the second elastic member to perform an automatic-retraction operation.

  • Publication number: 20240096996
    Abstract: A semiconductor device includes a first dielectric layer, a stack of semiconductor layers disposed over the first dielectric layer, a gate structure wrapping around each of the semiconductor layers and extending lengthwise along a direction, and a dielectric fin structure and an isolation structure disposed on opposite sides of the stack of semiconductor layers and embedded in the gate structure. The dielectric fin structure has a first width along the direction smaller than a second width of the isolation structure along the direction. The isolation structure includes a second dielectric layer extending through the gate structure and the first dielectric layer, and a third dielectric layer extending through the first dielectric layer and disposed on a bottom surface of the gate structure and a sidewall of the first dielectric layer.

  • Patent number: 11916487
    Abstract: An asymmetric half-bridge converter is provided. The asymmetric half-bridge converter includes a switch circuit, a resonance tank, a current sensor, and a controller. The current sensor senses a waveform of a resonance current flowing through the resonance tank to generate a sensing result. The controller determines the sensing result. When the sensing result indicates that an ending current value of a primary resonance waveform of the resonance current is greater than a predetermined value, the controller performs a first switching operation on the switch circuit. When the sensing result indicates that the ending current value of the primary resonance waveform is less than or equal to the predetermined value, the controller performs a second switching operation on the switch circuit.

  • Publication number: 20220216396
    Abstract: A memory device and a manufacturing method thereof are provided. The memory device includes a magnetic tunneling junction (MTJ) and a spin Hall electrode (SHE). The MTJ includes a free layer, a reference layer and a barrier layer lying between the free layer and the reference layer. The SHE is in contact with the MTJ, and configured to convert a charge current to a spin current for programming the MTJ. The SHE is formed of an alloy comprising at least one heavy metal element and at least one light transition metal element. The heavy metal element is selected from metal elements with one or more valence electrons filling in 5d orbitals, and the light transition metal element is selected from transition metal elements with one or more valence electrons partially filling in 3d orbitals.

  • Publication number: 20130033427
    Abstract: An image input system and an image input method thereof are disclosed. The system includes an input equipment which includes an image capturing module and a first communication module, and a processing apparatus which includes a second communication module, a calculation module and a conversion module. The image capturing module is configured to capture an image of an object on a display and to detect an image-capturing distance or a position of the object. The captured image, the image-capturing distance or the object position is then communicated to the processing apparatus and may be analyzed by the calculation module to calculate an edge position of the image. The conversion module is configured to convert the edge position, the captured image or the object position to an input signal. This invention creates a new type of human-machine interface through the image capturing module, and the first and second communication modules.
