  • Patent number: 8043939
    Abstract: To provide a method for manufacturing an SOI substrate having a single crystal semiconductor layer having a small and uniform thickness over an insulating film. Further, time of adding hydrogen ions is reduced and time of manufacture per SOI substrate is reduced. A bond layer is formed over a surface of a first semiconductor wafer and a separation layer is formed below the bond layer by irradiating the first semiconductor wafer with H3+ ions by an ion doping apparatus. H3+ ions accelerated by high voltage are separated to be three H+ ions at a semiconductor wafer surface, and the H+ ions cannot enter deeply. Therefore, H+ ions are added into a shallower region in the semiconductor wafer at a higher concentration than the case of using a conventional ion implantation method.

  • Patent number: 8039363
    Abstract: A method of expanding the contact pitch for un-diced chips in an array by pre-slicing the array in a first direction, attaching a lead frame to the chips' contacts, and then slicing the array and attached lead frame in the second direction. The lead frame has leads mechanically connected one another such that slicing the frame in the second direction along the mechanical connections separates the leads. Each lead has a first terminal which is conductively attached to a chip contact and a second terminal extending beyond the boundaries of the chip to which the first terminal is attached. In this manner, the contact pitch is effectively expanded to the terminal pitch of the leads.

  • Patent number: 8039378
    Abstract: To provide a technique capable of improving the reliability of a semiconductor element and its product yield by reducing the variations in the electrical characteristic of a metal silicide layer. After forming a nickel-platinum alloy film over a semiconductor substrate 1, by carrying out a first thermal treatment at a thermal treatment temperature of 210 to 310° C. using a heater heating device, the technique causes the nickel-platinum alloy film and silicon to react with each other to form a platinum-added nickel silicide layer in a (PtNi)2Si phase. Subsequently, after removing the unreacted nickel-platinum alloy film, the technique carries out a second thermal treatment having the thermal treatment temperature higher than that of the first thermal treatment to form the platinum-added nickel silicide layer in a PtNiSi phase. The temperature rise rate of the first thermal treatment is set to 10° C./s or more (for example, 30 to 250° C.

  • Patent number: 8034725
    Abstract: This invention provides a high throughput PECVD process for depositing TEOS films in a multi-station sequential deposition chamber. The methods significantly reduce the number of particles in the TEOS films, thereby eliminating or minimizing small bin defects. The methods of the invention involve dedicating a first station for temperature soak while flowing purge gas. Stopping the flow of reactant gas and flowing the purge gas for station 1 eliminates TEOS condensation on a cold wafer surface and significantly reduces the number of defects in the film, particularly for short temperature soaks.
