Title: Air-tight terminal and piezoelectric vibrator
Inventor: ENDO HIDEO
IPC: H01L23/48
Filed: 1990-11-26
Abstract: PURPOSE:To obtain an air-tight terminal with high reliability used for a crystal resonator by coating the surface of a lead wire with Pb/Sn solder plating whose Pb content is 80% or over and Pb/Sn solder plating whose Pb content is 40% or below. CONSTITUTION:Two lead wires are sealed in air-tightness and with insulation as an air-tight terminal through a glass 2 in a metallic outer ring 1. A Cu 6 is coated to the surface of an inner lead 4 as a covar 5 being a core, and Pb/Sn solder (the Pb content is 80% or over) 7 is coated and Pb/Sn solder (the Pb content is 40% or below) 8 is coated. Thus, in the process to fix a crystal chip and the lead of the air-tight terminal, the Pb/Sn 8 with a low eutectic temperature is molten at first and flows to the electrode on the crystal chip, acting like an initiating agent to solve the Pb/Sn 7 with a high crystal temperature thereby improving the flow of solder. Thus, the adhesion strength is increased and the reliability is improved.

IPC: H01L27/088
Filed: 1990-11-26
Abstract: PURPOSE:To efficiently generate a bias voltage even when a low-voltage power source is used by setting the threshold voltage of a transistor used for a charge pump circuit which generates a substrate bias voltage lower than that of other transistors. CONSTITUTION:Transistors Q1-Q4 pumps charges from a substrate under the control of an oscillator OSC 61 to generate a bias voltage 62. When the voltage becomes higher than a prescribed value, the frequency of the OSC 61 becomes low by the operation of a limitter circuit 52 and a charge pump circuit only operates intermittently. Even when a low-voltage power source is used, the threshold voltages of the Q1-Q4 must be lowered so as to suppress power consumption of the Q1-Q4. In order to lower the threshold voltages, a method for reducing the doping quantity of impurity in the well of one conductivity type 81 when producing the Q1-Q2 a method for shortening the channel length L2 of these transistors as compared with the channel length L1 of other circuit transistors is effective.

Patent JP-H06275558-A (JP)
Title: Manufacture of semiconductor device
Inventor: YANO KOSAKU
IPC: H01L21/285
Filed: 1993-12-22
Abstract: PURPOSE:To prevent the occurrence of spiking by preventing the reaction between a semiconductor substrate and an aluminum film. CONSTITUTION:When an opening is formed by etching off an insulating film until an Si substrate 11 is exposed, the entire exposed surface of the substrate 11 in the opening is coated with SiOH. When the surface of the substrate 11 is coated with hexamethyldisilazane, a molecular layer 12 in which the H of the SiOH is replaced with Si(CH3)3 is formed on the surface of the substrate 11. When aluminum atoms come flying onto the layer 12 during a sputtering process, the aluminum atoms collide with the layer 12 and sputter the hydrocarbon (CHx), etc., constituting the layer 12, but an SiOxCyH2 layer 12' which is formed due to a change in the layer 12 is left between an aluminum film and the substrate 11. Since the layer 12' prevents the mutual diffusion of aluminum in the aluminum film into the substrate 11 and Si in the substrate 11 into the aluminum film, the occurrence of spiking is prevented.

Title: Automatic control method
Inventor: NISHIMURA SHIGEO
IPC: G05B11/42
Filed: 1990-11-26
Abstract: PURPOSE:To perform automatic control which is started up fast and has a small overshoot determining the control output quantity by adding an integral term when the sum of a proportional term and a bias quantity is 0 - 100% of a control output quantity or without adding the integral term when not. CONSTITUTION:A controller 11 is equipped with a detection device 12, a setting device 13, and a PID controller 14. The controller 14 operates the control output quantity (m) from the deviation (e) between a set value from the device 13 and a measured value from the device 12 by using equations I and II. Here, PB is a bias quantity. When the sum (Kp.e+PB) of the proportional term Kp.e and bias quantity PB is 0 - 100% of the output quantity (m), namely, enters a proportional zone, the equation I is used and the integral term is added to operate the control output (m). When not, the equation II is used to operate the control output quantity (m) without adding the integral term. Thus, the integral term is not added until the proportional zone is entered, and added when the proportional term is entered. Consequently, a fast startup is realized when there is the bias quantity and the integral term is not added until the proportional zone is entered, so the overshoot is small and the deviation is eliminated.
