  • Patent number: 11721144
    Abstract: This disclosure is generally directed to systems and methods for eliminating false activation of components of a vehicle when the vehicle is parked in a garage. Example components can be a door lock, a door latch, a door activation servomotor, or a light. In an example method, a vehicle entry authorization system of a vehicle operates a sensor system to obtain dimensional information of an interior portion of the garage. The vehicle entry authorization system may then detect a presence of a mobile device (such as a phone-as-a-key or a vehicle key fob) and determines the location of the mobile device based on the dimensional information. If the mobile device is located outside the garage, the vehicle entry authorization system refrains from activating a component of the vehicle. However, if the mobile device is located inside the garage, the vehicle entry authorization system activates the component.

    Abstract: An electrostatic discharge (ESD) protection circuit, methods of fabricating an ESD protection circuit, methods of providing ESD protection, and design structures for an ESD protection circuit. An NFET may be formed in a p-well and a PFET may be formed in an n-well. A butted p-n junction formed between the p-well and n-well results in an NPNP structure that forms an SCR integrated with the NFET and PFET. The NFET, PFET and SCR are configured to collectively protect a pad, such as a power pad, from ESD events. During normal operation, the NFET, PFET, and SCR are biased by an RC-trigger circuit so that the ESD protection circuit is in a high impedance state. During an ESD event while the chip is unpowered, the RC-trigger circuit outputs trigger signals that cause the SCR, NFET, and PFET to enter into conductive states and cooperatively to shunt ESD currents away from the protected pad.

  • Patent number: 8242613
    Abstract: A semiconductor die has rows of bond pads along the edges of a major surface. The corners of the die are designated as keep out areas, with design layout rules prohibiting a probe-able bond pad from being placed in the keep out areas so that a minimum distance may be maintained between distal ends of adjacent rows of bond pads (i.e., bond pads along adjacent edges). The bond pads of each row have IO pad areas that are aligned with each other and IO probe areas that are aligned with each other. A generally L-shaped bond pad includes a first, vertical part that extends inwardly from an edge of the semiconductor die and a second, horizontal part connected to the vertical part. The L-shaped bond pad may be placed between a last bond pad in a row and a corner keep out area, and the second part of the L-shaped bond pad extends into the corner keep out area.

  • Patent number: 8154054
    Abstract: In a semiconductor chip in which external connection pads are arranged in three or more rows in a staggered configuration at the peripheral portion thereof, a first pad which is arranged in the outermost row is used as a power supply pad or a ground pad for an internal core circuit. To the first pad, a second pad which is arranged in the second outermost row is connected with a metal in the same layer as a pad metal. The resistance of a power supply line to the internal core circuit has a value of the parallel resistance of a resistance from the first pad and a resistance from the second pad, which is by far lower than the resistance from the first pad. Therefore, it is possible to prevent circuit misoperation resulting from an IR drop in the power supply of the internal core circuit.

  • Patent number: 8071407
    Abstract: An active device array substrate and its fabricating method are provided. According to the subject invention, the elements of an array substrate such as the thin film transistors, gate lines, gate pads, data lines, data pads and storage electrodes, are provided by forming a patterned first metal layer, an insulating layer, a patterned semiconductor layer and a patterned metal multilayer. Furthermore, the subject invention uses the means of selectively etching certain layers. Using the aforesaid means, the array substrate of the subject invention has some layers with under-cut structures, and thus, the number of the time-consuming and complicated mask etching process involved in the production of an array substrate can be reduced. The subject invention provides a relatively simple and time-saving method for producing an array substrate.

  • Patent number: 8067277
    Abstract: An active matrix pixel device is provided, for example an electroluminescent display device, the device comprising circuitry supported by a substrate and including a polysilicon TFT (10) and an amorphous silicon thin film PIN diode (12). Polysilicon islands are formed before an amorphous silicon layer is deposited for the PIN diode. This avoids the exposure of the amorphous silicon to high temperature processing. The TFT comprises doped source/drain regions (16a,17a), one of which (17a) may also provide the n-type or p-type doped region for the diode. Advantageously, the requirement to provide a separate doped region for the photodiode is removed, thereby saving processing costs. A second TFT (10b) having a doped source/drain region (16b,17b) of the opposite conductivity type may provide the other doped region (16b) for the diode, wherein the intrinsic region (25) is disposed laterally between the two TFTs, overlying each of the respective polysilicon islands.

  • Publication number: 20110089470
    Abstract: In a semiconductor device, a plurality of interface cells is disposed on four sides of an LSI chip in connection with a logic circuit area including a plurality of logic cells. Each interface cell may include four functional blocks which are vertically or horizontally aligned without being rotated, thus forming an I/O buffer. The left I/O buffer has a vertical layout in which functional blocks are vertically aligned, whilst the upper I/O buffer has a horizontal layout in which functional blocks are horizontally aligned. This makes it possible to fix the same length direction of gates of transistors with respect to both the functional blocks of I/O buffers and the logic cells, so that engineers do not need to consider characteristic variations of transistors due to positional differences of transistors when designing the circuitry of an LSI chip.
