  • Patent number: 11929273
    Abstract: A system and computer-implemented method are provided for manufacturing a semiconductor electronic device. An assembler receives a jig and a boat supporting a die. The assembler includes a separator that separates the jig into a first jig portion and a second jig portion and a loader that positions the boat between the first jig portion and the second jig portion. A robot receives an assembly prepared by the assembler and manipulates a locking system that fixes an alignment of the boat relative to the first jig portion and the second jig portion to form a locked assembly. A process chamber receives the locked assembly and subjects the locked assembly to a fabrication operation.

  • Patent number: 11749750
    Abstract: A split-gate trench device chip has an active region in which a plurality of active trenches are disposed. The active region is enclosed by termination trenches disposed in a termination region, which extends to the edges of the chip. A gate metal lead is disposed on the device surface. The gate metal lead makes contact to gate electrodes in the active trenches through contact holes disposed in the active region. A source or a drain metal lead is also disposed on the surface. The source or the drain metal lead makes contact to the field plate electrodes through contact holes disposed outside the active region. Each active trench in the active region has a first end merge into a first termination trench and a second end separated from an adjacent second termination trench.

  • Patent number: 8531458
    Abstract: An exemplary method of determining a pointing object position for three-dimensional interactive system, adapted for an interaction between a pointing object and a three-dimensional interaction display with embedded optical sensors. The method includes the steps of: acquiring a two-dimensional detected light intensity distribution caused by the pointing object acting on the three-dimensional interaction display; obtaining two light-shading intensity maximum values according to the two-dimensional detected light intensity distribution; and determining a one-dimensional positional information of the pointing object on a distance direction of the pointing object relative to the three-dimensional interaction display by use of the positional distance between the two light-shading intensity maximum values.
