Patent JP-H01228171-A (JP)
Title: Bipolar transistor
Inventor: UENO KATSUNOBU
IPC: H01L21/331
Filed: 1988-03-09
Abstract: PURPOSE:To improve emitter injection efficiency and to render a base thinner by a method wherein a specified thickness of SiNX is positioned between an NPN transistor polycrystalline silicon emitter and base. CONSTITUTION:An N-type collector 1 and P-type base 2 are provided in a single crystal Si substrate, and an N<+>-type polycrystalline Si layer 3 is formed on the surface of the base 2 through the intermediary of a 20-100Angstrom -thick silicon nitride (SiNX) film 7. The tunneling probability of electrons in terms of the SiNX 7 being several times higher than that of holes. The hole current decreases and the electron current relatively increases in this design because the SiNX film 7 of such a character is near the emitter/base junction. This increases emitter injection efficiency, enriches impurity concentration in the base 2, and keeps the emitter injection efficiency at a high level, all of which contribute to the realization of a base 2 that is shallow.

Title: Reactive ion etching method of silicon
Inventor: HIRAYAMA TERUMINE
IPC: H01L21/302
Filed: 1984-03-22
Abstract: PURPOSE:To etch even polycrystalline silicon containing an impurity, such as P, As, etc. selectively according to a fine pattern with high accuracy by using a gas, in which hydrogen is added to a chlorine group gas, or a hydrogen compound gas of chlorine as an etching gas. CONSTITUTION:A gas in which hydrogen is added to a chlorine group gas or a hydrogen compound gas of chlorine is employed as an etching gas in a reactive ion etching method for silicon. When polycrystalline silicon, which is formed on an silicon oxide SiO2 foundation layer and to which phosphorus is thermally diffused, is etched, SiCl4 gas is introduced into a reaction vessel in quantity of 40SCCM, introducing power is brought to 0.2W/cm<2>, gas pressure is brought to 0.05Torr, H2 gas is added to SiCl4 gas, and polycrystalline silicon is etched by reactive ions. The anisotropy of etching is promoted at that time. That is, the degree of progress of etching in the thickness direction of a polycrystalline silicon layer is made remarkably larger than that in the surface direction.

Title: Detection system for data start point
Inventor: MATSUMURA NOBUHIRO
IPC: G06F7/22
Filed: 1978-05-12
Abstract: PURPOSE: To increase the reliability of the start point detection, by dividing the bit pattern of serial data into three bit-groups and by taking them as the start point of serial data when the two of them are in agreement with the bit-pattern determined.  
     CONSTITUTION: The sink byte representing the start point of the serial data for magnetic discs is classified into three groups, e.g. the bit groups as shown in Fig. (a). The serial data is inputted from the lower side of the shift register SR and shifted upward. The AND gates A 1  to A 3  detect the pattern of four-bit from the upper side of SR, and the output is decided for the majority with the logic circuit of decision by majority consisting of the AND gates A 1  to A 6  and the OR gate. Among the first to the third bit groups, if the bit pattern of one group differs from that determined from the deficiency of the disc surface, either one of the gates A 4  to A 6  outputs 1 and the sink byte detection signal is outputted. Thus, the start point of data is ensured and the increase in the yield rate can be made.

When the subsidiary oil feed port 22 is communicated to the opening 12 of the piston chamber 2, a main jet flow of oil 18 begins to be ejected from the main port 16 along a sliding surface 19. Here, the main jet flow 18 of oil is deflected through a large angle in a direction increasing the injection angle theta by a subsidiary jet flow 23 of oil ejected from the subsidiary port 22 in a direction substantially parallel to the axis of a piston 4. Therefore, it is enabled to prevent errosion by the main jet flow of oil.
