  • Patent number: 7582935
    Abstract: A method of manufacturing an SOI substrate for semiconductor devices is described. The method includes forming a low density impurity region in a first semiconductor substrate and a high density impurity region in the low density impurity region, forming a trench surrounding the low density impurity region and the high density impurity region, the depth of the trench being deeper than the high density impurity region and shallower than the low density impurity region, forming an insulating layer on the surface of the first semiconductor substrate to fill the inside of the trench, attaching a second semiconductor substrate on the surface of the insulating layer, and removing a part of the first semiconductor substrate so that the bottom of the trench is exposed.

  • Patent number: 5863375
    Abstract: Wafer debonding of a bonded bulk wafer and a device wafer using a liquid jet to avoid scratching of the wafers is provided. The wafer debonder includes a wafer loader having a first stand with a flat upper surface and a second stand located above the first stand having a lower surface slanted with respect to the upper surface of the first stand at a predetermined angle. A first holder is connected to the first stand and a second holder is located on an imaginary surface extended from the lower surface of the second stand for holding the wafers. A liquid jetting nozzle is positioned adjacent the wafer loader to direct a jet of liquid at the interface between the wafers to separate the wafers.

  • Patent number: 5746883
    Abstract: An apparatus for bonding semiconductor wafers firmly bonds the wafers to each other and can always lay the bonded wafers on a desired bonding plate. The bonding plates have a plurality of grooves formed on their respective surfaces to reduce the bond force between the wafers and the bonding plates of the apparatus, and to prevent the wafers from sliding off the plates due to an air cushion. An interval controlling pin projects from the surface of one of the bonding plates to reduce breakage of the wafers by maintaining an interval between the bonding plates as they are are rotated towards each other. An elastic pad portion is installed on one the bonding plates for providing an elastic force for the wafers placed on the bonding plates so that the wafers bond to each other properly when the bonding plates are further rotated towards each other.
