Title: Bipolar transistor
Inventor: DEIIMUSU RANDEI HOORINGUSUWAAS
IPC: H01L21/331
Filed: 1995-07-24
Abstract: PROBLEM TO BE SOLVED: To enable high-speed switching by growing an epitaxial layer having a first conductivity type on the embedded-region collector provided with the first conductivity type, and forming a separating means around a transistor region. SOLUTION: A shallow emitter 49 is formed in a base region 48 by diffusion from a phosphorus-doped polysilicon emitter 64. A deep N<+> -type collector contact 62 is formed in an epitaxial region 14 and brought into contact with a DUF region 12, acting as an embedded collector. A metallic contact 78 is formed on the surface and insulated from the epitaxial region 14 by a thermally grown oxide 20a and a nitride layer overlapped thereon. Thus, the electrostatic capacity of a conductor is decreased. In this way, the filling density can be enhanced, and doping of an active base can be strengthened. Therefore, the delay (or switching time) of the gate can be made further smaller.

CONSTITUTION:A laser light from a projector 20 is made to irradiate end faces 182 and 183 of a cylinder roller 18 turned with a driving roller repeatedly from one end to the other and then, received with a light receiver 30 to form an image for scanning. At this point, the reflected lights from both the end faces 182 and 183 of the roller 18 are cut with a polaroid filter of the device 30 though scattered hitting a part of a device in an optical system and hence, only those reflected lights presenting the condition of both the end faces 182 and 183 of the roller 18 can be received. This assures a sufficient S/N ratio thereby enabling detection of the finest defect. An electrical signal converted from light with an photoelectric multiplier tube 27 is amplified 28 and an optical signal waveform is inputted into a discriminator 50 to discriminate the propriety in the working of both the end faces 182 and 183 of the roller 18 in comparison with a comparison level for detecting the object being inspected previously stored.
