  • Patent number: 11996837
    Abstract: A fuse structure includes first and second transistors where each of the first and the second transistors has a source terminal, a drain terminal, and a gate terminal; a first source/drain contact disposed on the source terminal of the first transistor; a second source/drain contact disposed on the drain terminal of the second transistor; an insulator disposed laterally between the first and the second source/drain contacts; a source/drain contact via disposed on the first source/drain contact; and a program line connected to the source/drain contact via, wherein a width of the insulator is configured such that a programming potential applied across the source/drain contact via and the drain terminal of the second transistor causes the insulator to break down.

  • Patent number: 11948935
    Abstract: Provided is a tap cell including a substrate, a first well, a second well, a first doped region, and the second doped region. The substrate has a first region and a second region. The first well has a first dopant type and includes a first portion disposed in the first region and a second portion extending into the second region. The second well has a second dopant type and includes a third portion disposed in the second region and a fourth portion extending into the first region. The first doped region having the first dopant type is disposed in the second portion of the first well and the third portion of the second well along the second region. The second doped region having the second dopant type is disposed in the first portion of the first well and the fourth portion of the second well along the first region.

  • Publication number: 20240096873
    Abstract: Electrostatic discharge (ESD) structures are provided. An ESD structure includes a semiconductor substrate, a first epitaxy region with a first type of conductivity over the semiconductor substrate, a second epitaxy region with a second type of conductivity over the semiconductor substrate, and a plurality of semiconductor layers. The semiconductor layers are stacked over the semiconductor substrate and between the first and second epitaxy regions. A first conductive feature is formed over the first epitaxy region and outside an oxide diffusion region. A second conductive feature is formed over the second epitaxy region and outside the oxide diffusion region. A third conductive feature is formed over the first epitaxy region and within the oxide diffusion region. A fourth conductive feature is formed over the second epitaxy region and within the oxide diffusion region. The oxide diffusion region is disposed between the first and second conductive features.

  • Publication number: 20090110234
    Abstract: An image processing method for providing an output image for an instant messaging program is provided. The image processing method includes the following steps. Firstly, an image capturer captures an input image. Next, the input image is inputted to a dump memory block. Then in response to an operating event, a drawing data is input to a canvas memory block. The storing sizes of the dump memory block and the canvas memory block are substantially the same. Next, the drawing data is obtained from the canvas memory and is combined with the input image, so that an output image is generated in the dump memory block. The instant messaging program controls a virtual image capturer to obtain the output image from the dump memory block.
