Abstract: PURPOSE:To reduce the number of times of heating in a fabrication process and prevent any hillock from being produced even though a lower electrode and a lower wiring are formed with an Al alloy by forming a protective insulating film covering the surface with a silicon nitride film formed at low temperature. CONSTITUTION:A protective insulating film 10 is formed by a process wherein a room temperature substrate 1 is transferred into a film formation chamber and just thereafter plasma discharge is produced in an atmosphere of process gas to deposit an SiN film on the substrate 1. Thus, there is formed at low temperature the protective insulating film 10 which is formed finally in the fabrication of a thin film transistor. There is accordingly reduced the number of times of heating to several hundreds of degrees centigrade a gate electrode and a gate wiring being a lower electrode and a lower wiring respectively in the fabrication process of the thin film transistor. Thus, the gate electrode and the gate wiring can be formed with an Al alloy containing a little amount of high melting point metal.

Title: Digital image forming device
Inventor: KAWAMURA FUMIO
IPC: H04N1/04
Filed: 1991-12-17
Abstract: PURPOSE:To reduce the job man-hour in the resist adjustment by executing the revision control in which a forming position of a test pattern picture is revised for each recording paper with a resist adjustment function. CONSTITUTION:After the resist automatic change mode is set, when a start key is depressed, the adjustment quantity in the longitudinal and lateral directions as a preset quantity is revised for each recording to output a test pattern picture. Picture data to output a test pattern picture 401a and a mark 401b are stored in a picture write section 103 and a ROM, and when the resist automatic change mode is started, a video controller 104 reads the data from the ROM and writes the data onto a photosensitive body. The picture 401a is used to recognize the write start position in the main scanning and subscanning direction. Furthermore, the formed position and number of bars of the mark 401b represent the adjustment quantity. Since the test pattern picture is outputted while its adjustment quantity is revised as preset, the adjustment quantity is discriminated depending on a way of output of recording paper on which the picture is formed at a proper position.

Abstract: PROBLEM TO BE SOLVED: To suppress the dispersion of elements and to differentially amplify sensitivity by providing a sense amplifier control means for feeding back the output signal of a sense amplifier for first and second precharging transistors and controlling the input offset voltage of the sense amplifier. SOLUTION: When the potential of a bit line Bit is lower than reference potential, a precharging transistor is turned on and precharging to the bit line Bit is started. When precharging to the bit line Bit is terminated, the output signal of a sense amplifier SA1 becomes a high level. Data latched by a latch circuit LAT1 is made to be a low level and a precharging circuit is stopped. A difference between bit line potential and reference potential is judged by the sense amplifier SA1 and a judged result is fed back, Thus, the input offset voltage of the sense amplifier owing to the dispersion of the elements is compensated and the differential amplification operation of high sensitivity can be executed.
