  • Patent number: 10727647
    Abstract: Tensile strained germanium is provided that can be sufficiently strained to provide a nearly direct band gap material or a direct band gap material. Compressively stressed or tensile stressed stressor materials in contact with germanium regions induce uniaxial or biaxial tensile strain in the germanium regions. Stressor materials may include silicon nitride or silicon germanium. The resulting strained germanium structure can be used to emit or detect photons including, for example, generating photons within a resonant cavity to provide a laser.

  • Patent number: 10580896
    Abstract: An SOI wafer contains a compressively stressed buried insulator structure. In one example, the stressed buried insulator (BOX) may be formed on a host wafer by forming silicon oxide, silicon nitride and silicon oxide layers so that the silicon nitride layer is compressively stressed. Wafer bonding provides the surface silicon layer over the stressed insulator layer. Preferred implementations of the invention form MOS transistors by etching isolation trenches into a preferred SOI substrate having a stressed BOX structure to define transistor active areas on the surface of the SOI substrate. Most preferably the trenches are formed deep enough to penetrate through the stressed BOX structure and some distance into the underlying silicon portion of the substrate. The overlying silicon active regions will have tensile stress induced due to elastic edge relaxation.

  • Patent number: 10418809
    Abstract: A power management integrated circuit includes pairs of high-side and low-side drivers, sensing circuitry, and a processor. The high-side and low-side drivers are used in combination with external discrete NFETs to drive multiple windings of a motor. The N-channel LDMOS transistor of each high-side driver has an associated isolation structure and a tracking and clamping circuit. If the voltage on a terminal of the integrated circuit pulses negative during a switching of current flow to the motor, then the isolation structure and tracking and clamping circuit clamps the voltage on the isolation structure and blocks current flow from the substrate to the drain. An associated ESD protection circuit allows the voltage on the terminal to pulse negative. As a result, a large surge of current that would otherwise flow through the high-side driver is blocked, and is conducted outside the integrated circuit through a body diode of an external NFET.

  • Patent number: 10411723
    Abstract: A Dynamic Triggering and Sample Engine (DTSE) that detects a first trigger received on a trigger input terminal that triggers a series of analog-to-digital conversions to be completed by an analog-to-digital converter circuit. The DTSE then determines a first sequence configuration stored in a sequence configuration table that is associated with the first trigger, causes a first analog-to-digital conversion to be performed using the first sequence configuration; causes a first analog-to-digital conversion result value to be stored in a sequence result table; and outputs an interrupt to a processor indicating that the first analog-to-digital conversion result value is available in the sequence result table. The interrupt is output from the DTSE before all remaining analog-to-digital conversions in the series are completed. In response to receiving the interrupt, the processor reads the analog-to-digital result value from the sequence result table via a bus.
