Abstract: Disclosed is a Zener diode having a scalable reverse-bias breakdown voltage (Vb) as a function of the position of a cathode contact region relative to the interface between adjacent cathode and anode well regions. Specifically, cathode and anode contact regions are positioned adjacent to corresponding cathode and anode well regions and are further separated by an isolation region. However, while the anode contact region is contained entirely within the anode well region, one end of the cathode contact region extends laterally into the anode well region. The length of this end can be predetermined in order to selectively adjust the Vb of the diode (e.g., increasing the length reduces Vb of the diode and vice versa). Also disclosed are an integrated circuit, incorporating multiple instances of the diode with different reverse-bias breakdown voltages, a method of forming the diode and a design structure for the diode.

Abstract: A micro vacuum gauge includes a substrate, a floating structure that is held above the substrate by a supporting structure extending from the substrate in a state where the floating structure is thermally isolated from the substrate, a heat generator that is arranged in the floating structure to generate heat, and a temperature sensor that is arranged in the floating structure to measure a difference in temperature between the substrate and the floating structure. A second member having a lower emissivity than a first member surrounding the heat generator and the temperature sensor is formed at least on a surface of the floating structure by being joined to the first member.

Abstract: The present disclosure provides systems and methods for configuring and constructing a single photo detector or array of photo detectors with all fabrications circuitry on a single side of the device. Both the anode and the cathode contacts of the diode are placed on a single side, while a layer of laser treated semiconductor is placed on the opposite side for enhanced cost-effectiveness, photon detection, and fill factor.

Abstract: A silicon controlled rectifier structure is provided in a substrate having a first conductive type. A well region formed within the substrate has a second conductive type. A first dopant region formed within the substrate and the well region has the first conductive type. A second dopant region formed within the substrate and a portion of the well region has the second conductive type. A third dopant region formed under the second dopant region has the first conductive type, in which the second and the third regions form a vertical Zener diode. A fourth dopant region formed within the substrate and separated from the second dopant region by a separation structure has the second conductive type. A fifth dopant region is formed within the substrate in a manner that the fourth dopant region is between the isolation structure and the fifth dopant region, and has the first conductive type.

The GD clamp diode includes multiple back-to-back doped regions in a polysilicon layer doped with dopant ions of a first conductivity type next to a second conductivity type disposed on an insulation layer above the MOSFET device, having an avalanche voltage lower than a source/drain avalanche voltage of the MOSFET device wherein the Zener diode is insulated from a doped region of the MOSFET device for preventing a channeling effect.

Abstract: An avalanche photodiode has improved low-noise characteristics, high-speed response characteristics, and sensitivity. The avalanche photodiode includes a first conductivity type semiconductor layer, a second conductivity type semiconductor layer, a semiconductor multiplication layer interposed between the first conductivity type semiconductor layer and the second conductivity type semiconductor layer, and a semiconductor light-absorbing layer interposed between the semiconductor multiplication layer and the second conductivity type semiconductor layer. The avalanche photodiode further comprises a multiplication suppressing layer which suppresses multiplication of charge carriers in the semiconductor light-absorbing layer, located between the semiconductor light-absorbing layer and the second conductivity type semiconductor layer.
