Abstract:
An ESD LUBISTOR structure based on FINFET technology employs a vertical fin (50) (a thin vertical member containing the source, drain and body of the device) in alternatives with and without a gate (60). The gate (60) may be connected to the external electrode (51) being protected to make a self-activating device and may be connected to a reference voltage (92). The device may be used in digital or analog circuits.
Abstract:
Disclosed is a method of forming a semiconductor structure that includes a discontinuous non-planar sub-collector having a different polarity than the underlying substrate. In addition, this structure includes an active area (collector) above the sub-collector, a base above the active area, and an emitter above the base. The distance between the discontinuous portions of the discontinuous sub-collector tunes the performance characteristics of the semiconductor structure. The performance characteristics that are tunable include breakdown voltage, unity current gain cutoff frequency, unity power gain cutoff frequency, transit frequency, current density, capacitance range, noise injection, minority carrier injection and trigger and holding voltage.
Abstract:
PROBLEM TO BE SOLVED: To provide a method and a structure for improving latch up characteristic of a semiconductor element. SOLUTION: Dual depth STI 20 is used for mutually separating wells. A trench contains a first substantially horizontal face in a first depth and a second substantially horizontal face in a second depth which is deeper than the first depth. An n-well 26 and a p-well 28 are formed on the respective sides of the trench. A heavily-doped region 18 is formed below the second substantially horizontal face of the trench in a substrate. The heaving-doped region is adjacent to the first and second wells, and the separation of the trench is extended.
Abstract:
PROBLEM TO BE SOLVED: To suppress a heat runway and improve stability of an ESD-inhibiting device in conjunction with a device scaling, by forming an in-plant under a shallow trench separation part of an ESD device. SOLUTION: An in-plant is formed under a trench separation structure of an ESD(Electrostatic Discharge) device. The in-plant is formed using a hybrid- resist. The hybrid resist formed the in-plant without any additional treatment such as mask-step. An ESD structure of a water part 2100 provides an ESD- inhibiting device function by connecting its input to the ESD device. A P++ diffusion part 2908 and an N-well 2920 constitute the first diode, and the P++ diffusion part 2908 becomes an anode and the N-well 2920 a cathode. Similarly, an N++ diffusion part 2904 and an N-well 2922 which are combined form a cathode of the second diode, and a P-type board becomes an anode.
Abstract:
PROBLEM TO BE SOLVED: To provide a method, a system, and an apparatus for operating a picosecond imaging circuit analysis (PICA)/high-current source system. SOLUTION: The picosecond imaging circuit analysis (PICA)/high current source system includes a step for applying a pulse from a high current pulse source to a device under test (DUT). A photodetector detects photon emission from the DUT. Using a signal from the photodetector, the photon emission from the DUT is mapped. A data processing means relates photon emission to a specific feature of the DUT. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide a silicon-on-insulator(SOI) element having both an element which is completely depleted and an element which is partially depleted on a common substrate. SOLUTION: The semiconductor structure which has a continuous buried oxide layer 24 and multiple trench separate structures 33 and 35 and its formation are disclosed. The buried oxide layer is arranged in the substrate at >=2 trench separate structures in depth. The trench separate structures are variable in depth and it is not important whether the trench separate structures are in contact with the buried oxide layer or not. The two trench separate structures enter the substrate to the same or different depths. The trench separate structures provide insulating separation between areas in the substrate and the separated areas may include a semiconductor element. The semiconductor structure makes it easy to provide a digital element and an analog element on a common wafer. The dual-depth buried oxide layer facilitates the formation of an asymmetrical semiconductor structure.
Abstract:
PROBLEM TO BE SOLVED: To provide a SOI semiconductor device, including a conductive stud for connecting a bulk active device and a SOI(silicon-on-insulator) device with each other. SOLUTION: Substrates 20, 23 are isolated by an embedded insulating layer 22, and there are injected substances for source and drain of the opposite polarities on layer regions 24, 25. An electrical connection 26 is partly isolated by an insulator 27 and an upper insulator 28. A region 21 is made of an injected substance of the same polarity or of opposite polarity to that of the bulk substrate 20. In the case where the dopants of the regions 23, 21, 20 have the same polarity, a SOI MOSFET body is a bulk contact or a thermal joint, and functions as a SOI MOSFET body contact. In the case where the dopants of the regions 23, 21 have the same polarity while the dopant of the region 20 has the opposite polarity, the SOI MOSFET body and the region 21 form a diode for the bulk substrate, which can be used for the polarity of the dopant used, for an example, in circuit application, voltage clamp, ESD(electrostatic discharge) protection, and other circuit functions.
Abstract:
PROBLEM TO BE SOLVED: To provide a structure for protecting an integrated circuit chip from other voltage fluctuations which are possible to give a static discharge (ESD) or a damage, and the method of manufacturing the structure. SOLUTION: The invention relates to a static discharge (ESD) protection structure between chips for a high speed and high frequency device comprising one or more direct transmission paths between chips. The invention specifically relates to the structure comprising (1) a first chip comprising a first circuit, (2) a second chip comprising a second circuit, and (3) an intermediate insulating layer arranged between the first chip and the second chip. The first circuit and the second circuit form a signal transmission path for transmitting a signal via the intermediate insulating layer. A static discharge (ESD) protection path is formed in the structure between the first chip and the second chip via the intermediate insulating layer, and protects the signal transmission path from ESD damage.
