  • Patent number: 7800735
    Abstract: Substrate support apparatus and methods are described. Motion of a substrate chuck relative to a stage mirror may be dynamically compensated by sensing a displacement of the substrate chuck relative to the stage mirror and coupling a signal proportional to the displacement in one or more feedback loops with Z stage actuators and/or XY stage actuators coupled to the stage mirror. Alternatively, a substrate support apparatus may include a Z stage plate a stage mirror, one or more actuators attached to the Z stage plate, and a substrate chuck mounted to the stage mirror with constraints on six degrees of freedom of movement of the substrate chuck. The actuators impart movement to the Z stage in a Z direction as the Z stage plate is scanned in a plane perpendicular to the Z direction. The actuators may include force flexures having a base portion attached to the Z stage plate and a cantilever portion extending in a lateral direction from the base portion.

  • Patent number: 7795108
    Abstract: A method for determining the depth etch, a method of forming a shielded gate trench (SGT) structure and a semiconductor device wafer are disclosed. A material layer is formed over part of a substrate having a trench. The material fills the trench. A resist mask is placed over a test portion of the material layer thereby defining a test structure that lies underneath the resist mask. The resist mask does not cover the trench. The material is isotropically etched and a signal related to a resistance change of the test structure is measured. A lateral undercut DL of the test structure is determined from the signal and an etch depth DT is determined from DL. The wafer may comprise one or more test structures forming a bridge circuit; one or more metal contacts that electrically connect the test structures through contact holes: and resist layer including over the test structures.

  • Patent number: 7792666
    Abstract: Emulation systems and method involving invalidating blocks of translated code in emulation of a target system on a host system in are disclosed. One or more blocks of target system code are translated by the host system to produce one or more corresponding blocks of translated code. The host system uses one or more native target system instructions as hints to invalidate or potentially invalidate one or more blocks of translated code. Blocks containing such hints cause the host system to mark some or all of the one or more blocks of translated code as potentially invalid. The potentially invalid blocks may be re-translated immediately. Alternatively, the potentially invalid blocks may be checked to see if the code in these blocks has been modified. If the code has been modified, corresponding blocks of target code may be re-translated.

  • Patent number: 7783061
    Abstract: Targeted sound detection methods and apparatus are disclosed. A microphone array has two or more microphones M0 . . . MM. Each microphone is coupled to a plurality of filters. The filters are configured to filter input signals corresponding to sounds detected by the microphones thereby generating a filtered output. One or more sets of filter parameters for the plurality of filters are pre-calibrated to determine one or more corresponding pre-calibrated listening zones. Each set of filter parameters is selected to detect portions of the input signals corresponding to sounds originating within a given listening zone and filter out sounds originating outside the given listening zone. A particular pre-calibrated listening zone is selected at a runtime by applying to the plurality of filters a set of filter coefficients corresponding to the particular pre-calibrated listening zone.

  • Patent number: 7778831
    Abstract: Voice recognition methods and systems are disclosed. A voice signal is obtained for an utterance of a speaker. A runtime pitch is determined from the voice signal for the utterance. The speaker is categorized based on the runtime pitch and one or more acoustic model parameters are adjusted based on a categorization of the speaker. The parameter adjustment may be performed at any instance of time during the recognition. A voice recognition analysis of the utterance is then performed based on the acoustic model.

  • Patent number: 7767526
    Abstract: Trench gate MOSFET devices may be formed using a single mask to define gate trenches and body contact trenches. A hard mask is formed on a surface of a semiconductor substrate. A trench mask is applied on the hard mask to predefine a body contact trench and a gate trench. These predefined trenches are simultaneously etched into the substrate to a first predetermined depth. A gate trench mask is next applied on top of the hard mask. The gate trench mask covers the body contact trenches and has openings at the gate trenches that are wider than those trenches. The gate trench, but not the body contact trench, is etched to a second predetermined depth. Conductive material of a first kind may fill the gate trench to form a gate. Conductive material of a second kind may fill the body contact trench to form a body contact.

  • Patent number: 7770050
    Abstract: Methods and systems for resolving clock management issues in emulation of a target system on a host system are disclosed. A first set of code instructions of a target program is interpreted to generate interpreted code instructions that emulate a first component on the host system. A second set of code instructions is translated to generate translated code instructions that emulate a second component of the target system on the host system. The interpreted instructions, are executed based on a first clock (which may be a fixed clock) and the translated instructions are executed based on a second clock (which may be a variable clock). The host system adjusts the first or second clock, execution of the translated or interpreted instructions or a memory access to maintain a desired synchronization between the translated instructions and the interpreted instructions.
