  • Patent number: 9269830
    Abstract: A junction field effect transistor comprising: a semiconductor substrate having a first conductivity type; a channel region having a second conductivity type different from the first conductivity type, and being formed in a surface of the semiconductor substrate; a first buried region having the second conductivity type, being formed within the channel region, and having an impurity concentration higher than the channel region; a first gate region having the first conductivity type, and being formed in a surface of the channel region; and first drain/source region and a second drain/source region both having the second conductivity type, which are formed each on an opposite side of the first gate region in the surface of the channel region, in which the first buried region is not formed below the second drain/source region, but is formed below the first drain/source region.

  • Publication number: 20050274966
    Abstract: A polysilicon fuse includes a fusing part to be fused through voltage application, a positive terminal side joint connected to one end of the fusing part and a negative terminal side joint connected to the other end of the fusing part. The positive terminal side joint that attains a high voltage through the voltage application has lower resistance and higher heat conductivity than the negative terminal side joint. Furthermore, a write operation is performed, with a current limiting resistance serially connected to a positive terminal side joint of a polysilicon fuse, by applying a voltage pulse to the polysilicon fuse through the current limiting resistance. Thus, a current flowing to the polysilicon fuse in fusing the fusing part is limited to a given range.

  • Publication number: 20050077594
    Abstract: A semiconductor device includes a polysilicon fuse with a fusion portion and has a sequential stack made of an interlayer insulating film having a recess above the fusion portion, a surface passivation film having an opening on the recess, a buffer film filling the recess and the opening, and a sealing resin layer. The buffer film releases film stress on the polysilicon fuse placed by the sealing resin layer, and avoids influences of the film stress on trimming of the device. In a method for trimming a semiconductor device, trimming is carried out by applying to the polysilicon fuse a voltage pulse capable of melting the polysilicon fuse at the fusion portion and interrupting the applied voltage with a current flowing through the fuse. This avoids influences of film stress placed by the sealing resin.

  • Patent number: 5931465
    Abstract: The present invention is embodied in a game device for playing a game in which a moving body is levitated above a play field board by air emitted from a number of holes formed in the play field board. A moving body feeding device automatically feeds the moving body onto the play field board. After use, the moving body is recovered, lifted above the play field board, and dropped into guides which guide the moving body onto the play field board.
