  • Patent number: 11226365
    Abstract: A glitch detection circuit includes a first P-type field-effect transistor and a second P-type field-effect transistor which are biased by the same current, and a channel width-to-length ratio of the first P-type field-effect transistor is higher than that of the second P-type field-effect transistor. A capacitor having a terminal grounded and another terminal connected to the gates of the first and second P-type field-effect transistors and a power supply terminal. A determination circuit configured to determine that a negative glitch occurs when a voltage decreasing amount of the drain of the first P-type field-effect transistor is greater than that of the second P-type field-effect transistor, and determine that a positive glitch occurs when an voltage increasing amount of the drain of the second P-type field-effect transistor is greater than that of the first P-type field-effect transistor.

  • Publication number: 20080022254
    Abstract: An integrated circuit (IC) design system includes an IC design module for generating various portions of a mask layout according to a predefined specification of an integrated circuit, a mask module for assembling the various portions of the mask layout and forming a tape-out of the mask layout for mask manufacturing, and an e-LOP module operable to convert at least a subset of the various portions of the mask layout in a GDS format at a design stage prior to forming the tape-out.

  • Patent number: 6043545
    Abstract: A MOSFET device protects the device from the short channel effect and decrease the resistance of a gate of the device. The MOSFET device includes a gate formed on a substrate and two source/drain regions. The source/drain regions are formed in the substrate at the sides of the gate. An oxide layer includes a first structure and a second structure. The first structure is at the side walls of the gate with the top of the first structure being lower than the top of the gate. The second structure is formed on the substrate and is connected to the first structure. A first spacer is formed on the second structure and beside the first structure. A second spacer is formed on the second structure and beside the first spacer. A self-aligned metal layer is formed on the gate, the first spacer, and over the substrate. As a result, the MOSFET device has an ultra-shallow junction under the first spacer to reduce the source/drain resistance and increase the operating rate of the device.

  • Patent number: 5920783
    Abstract: A method of fabricating a MOSFET device in accordance with the present invention can protect the device from the short channel effect and decrease the resistance of a gate of the device. The fabricating method includes the following steps. A device including a substrate, an oxide layer, a gate and a lightly doped region is provided, wherein the oxide layer is formed on the substrate and the gate is formed on the oxide layer. A conducting layer is formed on the oxide layer, and the conducting layer is etched to form a first spacer. Then, the device is implanted to form a heavily doped region. A dielectric layer is deposited on the device, and the dielectric layer is etched to form a second spacer. The oxide layer is etched to expose part of the side walls of the gate. Then, a self-aligned silicide is further processed to complete the fabricating processes.
