Patent JP-H023238-A (JP)
Title: Manufacture of thin film bipolar transistor
Inventor: KURAISON TORONNAMUCHIYAI
IPC: H01L21/331
Filed: 1988-06-20
Abstract: PURPOSE:To reduce base resistance by forming a base area narrowly by double- diffusion, and forming an insulation layer on a first conduction type emitter area and a collector area so as to form a base electrode. CONSTITUTION:In a P type polycrystal thin film 2 with low concentration are formed an N type base area 4, a P<+> type emitter area 3, and a P<+> type collector area 5b, and the residual area of the thin film 2, i.e., the area between the base area 4 and the collector area 5b comes to be a P<-> type collector area 5a. Hereupon, by controlling diffusion length which is determined by diffusion time, diffusion temperature, etc., at the time when diffusing N type impurity to form the base area and P type impurity to form the emitter area, the base width can be made small since the base width of the base area 4 can be decided by the difference of this diffusion length. Furthermore, an interlayer insulation film 10 is formed by thermally oxidizing the whole face. At this time, since the oxidation rate of a Si film 14 made porous is faster than that of parts that are not made porous, the oxide film on the P type Si becomes thicker than that on the N type Si.

Filed: 1986-06-27
Abstract: PURPOSE:To shorten the scan time by providing two status memories, which can be accessed with the same address, and a means which controls read/write permission and inhibition of both status memories independently of each other. CONSTITUTION:In the normal state, the same contents are written in both status memories 41 and 42 because gates G2 and G4 are opened, but contents of a first status memory 41 are read out because a gate G1 is opened and a gate G3 is closed. At the time of latching, a signal D is set to '0' to close the gate G4, and therefore, the status at this time is fixed in a second status memory 42. At the time of monitor, a signal C is set to '1' and the other signals are set to '0' to read and display fixed contents of the second status memory 42. Data is latched or read out by only gate control, and the control is efficiently performed without extending the scan time.
