Abstract: PROBLEM TO BE SOLVED: To adapt the electrical characteristics of a semiconductor device to prescribed specifications and to raise the yield of the manufacture of the product of the device, by a method wherein a metal wiring is heat-treated in the atmosphere of hydrogen gas while the electrical characteristics of a TFT are measured after a metal wiring heat-treating process, or the conditions of a heat treatment of the metal wiring are defined based on data on a measurement of the electrical characteristics of the TFT to heat-treat the metal wiring in the atmosphere of the hydrogen gas. SOLUTION: A channel layer of a TFT is formed of a polycrystalline silicon layer, and subsequently a gate electrode to control a current which is made to flow to a source electrode, a drain electrode and the channel layer, are formed. Then a metal wiring connected with the source, drain and gate electrodes is formed and a heat treatment of the metal wiring is performed in the atmosphere of hydrogen gas. At this time, while an on-state current and an off-state current in the TFT constituting load transistors L1 and L2 of an STRAM are detected, the heat treatment is performed and at the point of time when the on-state current and the off-state current respectively become a current of a value to correspond to the prescribed specifications, and the heat treatment is ended.  Because of this, the STRAM provided with the TFT having characteristics as defined in the specifications can be formed.

Title: Fluid quantity controller
Inventor: SAITO HIDEHARU
IPC: G05D7/00
Filed: 1990-09-11
Abstract: PURPOSE:To obtain stable control results by converting a fluid quantity set value based on a valve opening degree characteristic line peculiar to a control valve to obtain a valve opening degree set value and correcting this obtained set value based on the deviation of the fluid quantity set value from the actual fluid quantity to obtain a corrected set value and controlling the degree of valve opening to this corrected set value. CONSTITUTION:A limit valve opening degree thetac is so set that the area of a valve opening degree theta lower than this valve opening degree thetac is the theta control unstable area, and thereby, a control part 5 is controlled in accordance with a normal process feedback control method by a primary control part 8 when the valve opening degree signal theta is higher than thetac. When the valve opening degree signal theta is lower than thetac, thetais controlled to a valve opening degree command value thetar (the degree of valve opening obtained by correcting a valve opening degree set value thetas, which is unequivocally determined based on a valve opening degree characteristic 13 peculiar to a control valve 5 by the fluid quantity set value indicated by the set signal, by a valve opening degree correction value  thetas with which the average deviation of the fluid quantity is zero) by a secondary control part. Thus, theta is less changed even in the theta control unstable area because this device is independent of the process feedback control, and the control results are stabilized.
