  • Patent number: 9166017
    Abstract: Techniques capable of improving the yield of IGBTs capable of reducing steady loss, turn-off time, and turn-off loss are provided. Upon formation of openings in an interlayer insulting film formed on a main surface of a substrate, etching of a laminated insulating film of a PSG film and an SOG film and a silicon oxide film is once stopped at a silicon nitride film. Then, the silicon nitride film and the silicon oxide film are sequentially etched to form the openings. As a result, the openings are prevented from penetrating through an n-type source layer and a p+-type emitter layer having a thickness of 20 to 100 nm and reaching the substrate.

  • Patent number: 8939130
    Abstract: An evaporated fuel treatment device is provided to treat evaporated fuel by using a fuel supply cap with a small size while the flowout of fuel can also be suitably prevented. The evaporated fuel treatment device includes a positive pressure adjusting valve which opens when an inner pressure of a fuel tank becomes a predetermined pressure or more, and a spherical rollover valve which closes the positive pressure adjusting valve when the fuel tank is inclined at an angle equal to or larger than a predetermined angle. The positive pressure adjusting valve and the spherical rollover valve are mounted on one cylindrical portion formed on a fuel supply cap.

  • Patent number: 8813725
    Abstract: An evaporated fuel treatment device for a vehicle is provided to suppress the flowout of evaporated fuel into atmospheric air. In the evaporated fuel treatment device, a communication chamber is formed in a fuel supply cap, allowing communication between a charge passage and the inside of a fuel tank in a closed state. In the communication chamber, a positive pressure adjusting valve is openable to supply evaporated fuel in the fuel tank to an evaporated fuel storage unit through the communication chamber and the charge passage, and a negative pressure adjusting valve is openable to supply atmospheric air to the fuel tank from the evaporated fuel storage unit through the communication chamber and the charge passage. An interlocking member is provided between the key cover and the negative pressure adjusting valve, and opens the negative pressure adjusting valve in an interlocking manner with an operation of opening the key cover.
