  • Patent number: 7224049
    Abstract: A method of fabricating a lead frame for a semiconductor device having a semiconductor chip resin-sealed therein. The lead frame includes a lead to be electrically connected to the semiconductor chip within sealing resin and to be sealed into the sealing resin such that at least a part of its mounting surface is exposed from the sealing resin. The method includes a lead forming step for forming the lead, and a side edge coining step for subjecting a side edge of a sealed surface, which is a surface on the opposite side of the mounting surface, of the lead to coining processing from the side of the sealed surface, to form a slipping preventing portion. The slipping preventing portion is to project sideward from the lead and to have a slipping preventing surface between the mounting surface and the sealed surface of the lead.

  • Patent number: 7220647
    Abstract: A method of cleaning a wafer, adapted for a patterned gate structure. The gate structures comprise a gate dielectric layer, a nitrogen-containing barrier layer and a silicon-containing gate layer sequentially stacked over the substrate. The method includes cleaning the substrate with phosphoric acid solution and hydrofluoric acid solution so that silicon nitride residues formed in a reaction between the nitrogen-containing barrier layer and the silicon-containing gate layer can be removed and the amount of pollutants and particles can be reduced. Ultimately, the yield of the process as well as the quality and reliability of the device are improved.

  • Patent number: 7220607
    Abstract: In a lead frame, through holes are formed outside suspending leads and trenches are formed on a back surface along the suspending leads so as to communicate with the through holes. When sealing resin is injected into cavities of a resin molding die, air enters the through holes through air vents and flows out from the through holes by a resin injection pressure in the trenches, making it easier for the sealing resin to enter the through holes. Since the sealing resin leaking to the air vents can be injected into the through holes, it is possible to enhance the bonding force between the sealing resin after curing and the lead frame in the vicinity of the air vents and effect release of the resin molding die, while allowing the sealing resin leaking to the air vents to remain on the lead frame side without remaining within the air vents.

  • Patent number: 7220649
    Abstract: The method of manufacturing the semiconductor device that includes a high voltage MOS transistor with high operating voltage under both high and low gate voltages with low-cost is disclosed. When manufacturing the high voltage MOS transistor, a portion of a gate insulation film is removed to form an opening that exposes an outside area of the active area, which is outside of the central area where a gate electrode will be formed. A shallow grade layer is formed by implanting impurities into an opening with an energy that does not permit penetration of impurity ions through the gate insulation film.

  • Patent number: 7220627
    Abstract: The speed of the laser scanned by the scanning means such as a galvanometer mirror or a polygon mirror is not constant in the center portion and in the end portion of the scanning width. As a result, the object, for example an amorphous semiconductor film, is irradiated with the excessive energy and therefore there is a risk that the amorphous semiconductor film is peeled. In the present invention, in the case where the laser spot of the energy beam output continuously on the irradiated object is scanned by moving it back and forth with the use of the scanning means or the like, the beam is irradiated to the outside of the element-forming region when the scanning speed of the spot is not the predetermined value, for example when the speed is not constant, and accelerates, decelerates, or is zero, for example in the positions where the scanning direction changes, or where the scanning starts or ends.

    Abstract: Provided is a method of fabricating a recess transistor in an integrated circuit device. In the provided method, a device isolation region, which contacts to the sidewall of a gate trench and a substrate region remaining between the sidewall of the device isolation region and the sidewall of the gate trench, is etched to expose the remaining substrate region. Thereafter, the exposed portion of the remaining substrate region is removed to form a substantially flat bottom of the gate trench. The recess transistor manufactured by the provided method has the same channel length regardless of the locations of the recess transistor in an active region.

  • Patent number: 7217645
    Abstract: Solder is connected to the electrodes of the circuit board by using a temperature profile with a constant fusion temperature, a connection interface strength evaluation test is carried out on the soldered joints to obtain an appropriate reflow range free of decreases in the strength at the connection interface. On the basis of the appropriate reflow range obtained and using as the basis the chemical compound thickness which is determined uniquely by heat load, an appropriate reflow range in an optional temperature profile with one temperature peak is obtained. By carrying out connection in this appropriate reflow range, soldered joints can be obtained without decreases in the connection interface strength in the large-scale production stage.

  • Patent number: 7214628
    Abstract: A method of fabricating a gate of a transistor device on a semiconductor substrate, includes the steps of placing the substrate in a vacuum chamber of a plasma reactor and introducing into the chamber a process gas that includes oxygen while maintaining a vacuum pressure in the chamber. An oxide insulating layer on the order of several Angstroms in thickness is formed at the surface of the substrate by generating a plasma in a plasma generation region within the vacuum chamber during successive “on” times, and allowing ion energy of the plasma to decay during successive “off” intervals separating the successive “on” intervals, the “on” and “off” intervals defining a controllable duty cycle. During formation of the oxide insulating layer, the duty cycle is limited so as to limit formation of ion bombardment-induced defects in the insulating layer, while the vacuum pressure is limited so as to limit formation of contamination-induced defects in the insulating layer.
