Title: Small-region bipolar transistor
Inventor: RAJIBU AARU SHIYA
IPC: H01L29/73
Filed: 1991-04-26
Abstract: PURPOSE: To reduce latch up between adjoining NMOS and PMOS transistors by forming an emitter using a divided silicon deposition method. CONSTITUTION: A second polycrystalline silicon layer 126 is deposited on the entire surface of a processed wafer, for consolidation with a first layer 112. The second polycrystalline layer 126 forms a polysilicon composite layer 128 on a gate oxide 111 consisting of NMOS and PMOS transistors, a true poly- emitter, base interface district 125 of bipolar, and a collector 110. The polysilicon 128 is injected with such a high dosage of an N-type impurity as phosphorus (132). With polysilicon overlapped with the gate oxide 111, which is strongly doped and etched with a specified pattern, a gate conductor to respective NMOS and PMOS transistors is formed. Thereby, a lap between adjoining NMOS and PMOS transistors is reduced.

IPC: G01F1/32
Filed: 1986-04-25
Abstract: PURPOSE:To improve the durability of a sensor and to calculate the mass flow rate of air by installing a vortex generation body in the middle of a fluid passage, providing a lead pipe behind the vortex generation body, and guiding negative pressure generated by vortexes to a pressure sensor. CONSTITUTION:The vortex generation body 3 is provided in fluid and then the vortex generation body 3 generates vortexes 6 alternately as shown in a figure, so a pressure difference is generated nearby the window 41 of the lead pipe 4 and the frequency of the pressure difference is detected by the pressure sensor 5. The output of the sensor 5 is based upon the periodicity of the vortex generation and processed by a processing circuit into a signal. The period T of the signal is shorter and shorter as the flow rate of the air is larger and larger. Consequently, the suction air flow rate can be measured and mean atmospheric pressure is found by the sensor 5 to find the air concentration. Then, the mass flow rate of the air is calculated from those two data.
