  • Patent number: 12167594
    Abstract: In a method of manufacturing a semiconductor device, a memory cell structure covered by a protective layer is formed in a memory cell area of a substrate. A mask pattern is formed. The mask pattern has an opening over a first circuit area, while the memory cell area and a second circuit area are covered by the mask pattern. The substrate in the first circuit area is recessed, while the memory cell area and the second circuit area are protected. A first field effect transistor (FET) having a first gate dielectric layer is formed in the first circuit area over the recessed substrate and a second FET having a second gate dielectric layer is formed in the second circuit area over the substrate as viewed in cross section.

  • Publication number: 20240377436
    Abstract: A tunnel-type probe includes a tube, an elastic member, and a pin. The elastic member is assembled in the tube. The pin is movably disposed through the tube, and is electrically coupled to the tube by being connected to the elastic member. The pin has an inner segment, a contacting segment, and a limiting segment, the latter two of which are connected to two ends of the inner segment. The inner segment is arranged in the tube and is connected to the elastic member. The contacting segment and the limiting segment are respectively located at two opposite sides of the tube. When the tunnel probe abuts against a device under test (DUT) through the contacting segment, the pin is moved in a direction away from the DUT, such that the elastic member is deformed from being pressed by the pin so as to generate an elastic force.

  • Publication number: 20240377437
    Abstract: An open-type probe of a vertical probe card includes a frame, an elastic member, and a pin. The frame has an operation slot and two lateral openings being in spatial communication with the operation slot. The elastic member is assembled to the frame and is located in the operation slot. The pin includes an inner segment assembled in the operation slot and a contacting segment that protrudes from an opening of the operation slot. The pin abuts against the elastic member through the inner segment so as to be electrically coupled to the frame. The elastic member and the inner segment are arranged between the two lateral openings. The contacting segment is configured to abut against a device under test, so that the contacting segment is moved toward the operation slot to press the elastic member for deforming the elastic member to generate an elastic force.

  • Patent number: 11821081
    Abstract: This disclosure provides systems, methods, and apparatus related to thin free-standing oxide membranes. In one aspect, a method includes providing a substrate. The substrate defines a hole having a diameter of about 500 nanometers to 5000 nanometers. A layer of metal is deposited on the substrate. A supporting layer is deposited on the layer of metal. A first side of the supporting layer is the side that is disposed on the layer of metal. A metal oxide layer is deposited on the first side of the supporting layer and on the substrate. In some implementations, the method further includes removing the supporting layer.

  • Patent number: 11672124
    Abstract: The present disclosure relates to an integrated circuit that includes a semiconductor substrate having a periphery region and memory cell region separated by a boundary region. A pair of split gate flash memory cells are disposed on the memory cell region and include a first select gate and a first memory gate. A first gate electrode is disposed over a first gate dielectric layer on the periphery region. A second gate electrode is disposed over a second gate dielectric layer on the periphery region at a position between the boundary region and the first gate electrode. The second dielectric layer is thicker than the first gate dielectric layer. The first select gate and the first memory gate have upper surfaces that are co-planar or level with the upper surface of the second gate electrode.

  • Patent number: 10957704
    Abstract: The present disclosure relates to a structure and method for embedding a non-volatile memory (NVM) in a HKMG (high-? metal gate) integrated circuit which includes a high-voltage (HV) HKMG transistor. NVM devices (e.g., flash memory) are operated at high voltages for its read and write operations and hence a HV device is necessary for integrated circuits involving non-volatile embedded memory and HKMG logic circuits. Forming a HV HKMG circuit along with the HKMG periphery circuit reduces the need for additional boundaries between the HV transistor and rest of the periphery circuit. This method further helps reduce divot issue and reduce cell size.
