  • Patent number: 8742513
    Abstract: In a semiconductor device comprising sophisticated high-k metal gate structures formed in accordance with a replacement gate approach, semiconductor-based resistors may be formed above isolation structures substantially without being influenced by the replacement gate approach. Consequently, enhanced area efficiency may be achieved compared to conventional strategies, in which the resistive structures may have to be provided on the basis of a gate electrode metal, while, nevertheless, a low parasitic capacitance may be accomplished due to providing the resistive structures above the isolation structure.

  • Patent number: 8723294
    Abstract: It is possible to suppress a change in a resistance value caused by a potential of a semiconductor substrate 10 near a resistance element layer 13, a power line passing on or above the resistance element layer, or a signal line, without generating useless current or a distortion in a signal. A first conductive layer 15 biased by the potential of a first electrode 11 and a second conductive layer 16 biased by the potential of a second electrode 12 cover below the resistance element layer equally. A change in the resistance value caused by a potential difference between the resistance element layer and a neighboring semiconductor substrate 14 is cancelled by the first conductive layer and the second conductive layer covering at least one of above and below the resistance element layer with both ends biased, so the change in the resistance value is suppressed.

  • Patent number: 8610217
    Abstract: Disclosed are embodiments of a self-protected electrostatic discharge field effect transistor (SPESDFET). In the SPESDFET embodiments, a resistance region is positioned laterally between two discrete sections of a deep source/drain region: a first section that is adjacent to the channel region and a second section that is contacted. The second section of the deep source/drain region is silicided, but the first section adjacent to the channel region and the resistance region are non-silicided. Additionally, the gate structure can be either silicided or non-silicided. With such a configuration, the disclosed SPESDFET provides robust ESD protection without consuming additional area and without altering the basic FET design (e.g., without increasing the distance between the deep source/drain regions and the channel region).

  • Patent number: 8598681
    Abstract: The present disclosure is directed to a device and a method for forming a precision temperature sensor switch with a Wheatstone bridge configuration of four resistors and a comparator. When the temperature sensor detects a temperature above a threshold, the switch will change states. The four resistors in the Wheatstone bridge have the same resistance, with three of the resistors having a low temperature coefficient of resistance and the fourth resistor having a high temperature coefficient of resistance. As the temperature increases, the resistance of the fourth resistor will change. The change in resistance of the fourth resistor will change a voltage across the bridge. The voltage across the bridge is coupled to the comparator and compares the voltage with the threshold temperature, such that when the threshold temperature is exceeded, the comparator switches the output off.

    Abstract: The invention provides a method of manufacturing a semiconductor device having a semiconductor resistor layer, which reduces a difference between a theoretical resistance value and a measured resistance value. An interlayer insulation film is formed on the whole surface of a semiconductor substrate, and then the interlayer insulation film is selectively etched to form contact holes partially exposing a polysilicon resistor layer, a source region and a drain region. The patterning size of the polysilicon resistor layer is designed by defining the lengths between the adjacent contact holes on the polysilicon resistor layer as the lengths of resistor elements. Then, ion implantation is performed to the polysilicon resistor layer through the contact holes to form low resistance regions (regions where high concentration of impurities are implanted) on the polysilicon resistor layer.
