Title: Manufacture of semiconductor device
Inventor: TANIOKA YOSHIRO
IPC: H01L27/10
Filed: 1990-07-10
Abstract: PURPOSE:To manufacture a semiconductor device which secures cell capacity largely and decreases the exclusive area of a capacitor by providing a process of forming irregularity at the inwall of a trench of laminate structure by anisotropically etching the inside of a trench of laminate structure consisting of an insulating film with a resist film as a mask. CONSTITUTION:First, using an Si substrate as a semiconductor substrate 1, it is made into laminate structure 4 of five layers by growing first SiO2 films 2 and second SiO2 films 3 repeatedly. After formation of the laminate structure 4, with the resist film 5 as a mask, by anisotropic dry etching, a trench, which reaches the Si substrate 1, is made in a capacitor formation area. Subsequently, with the resist film 5 as a mask, the wet etching by hydrofluoric acid aqueous solution is performed to etch the inside of the trench 6, whereupon by the difference of the etching speed between the first SiO2 film and the second SiO2 film, irregularity is made at the inwall of the trench 6. By this method, the surface area of the trench is widened, so the security of cell capacity becomes easy, and also the exclusive area of the capacity can be made small.

Title: Step-down circuit device
Inventor: MATSUO HISATO
IPC: G05F1/56
Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To provide a step-down circuit device which has a standby mode so that even if a load current increases for some reason or other during the standby mode, a drop in output potential can be recovered speedily. SOLUTION: When a standby control signal is in standby mode, the potential VDD from an external supply source 1 is applied to the input terminal of a load current supply means 2. The potential at the output terminal of the load current supply means 2 in the stationary state of the standby mode at this time is denoted as VO. The potential VDD is applied to one end of the load current control part 4 and the potential VO is applied to the other end; and the load current control part 4 generates a potential corresponding to the potential difference at its output terminal to control the load current supply means 2. If the potential VO at the output terminal O varies for some reason or other, the potential difference applied to the load current control part 4 varies.  Then the potential generated at the output terminal of the load current control part 4 varies and the load control supply means 2 is adjusted to cancel the variation of the potential VO at the output terminal.

Title: Plant monitoring controller
Inventor: MIYAGAKI HISANORI
IPC: G05B23/02
Filed: 1988-07-22
Abstract: PURPOSE:To classify an operation edge and other operation edge during the operation and to easily and rapidly discover a misoperation by making the displaying method of the operation edge during the interruption of a manual operation different from the displaying method of other operation edge. CONSTITUTION:When an operation edge frame and a related schematic drawing are displayed, an operator pushes a mode button 4-1. For a signal, a discriminating part 110 discriminates the button classification and the corresponding operation edge and discriminating parts 111-113 respectively generate an operation edge selecting signal, the manual switching completing signal of an operation edge 12-1 and a manual operation edge condition signal. An operation signal switching part 114 switches the signal preparing output part from an automatic operation 115 to a manual operation 116. When the opening command is pushed by the button 4-1, an opening command signal is outputted from an output 116 to the operation edge 12-1, a displaying part 108 executes the processing based on the signal of the discriminating part 111, and when a manual operation to surround the operation edge 12-1 only by a flicker frame on a CRT2-2 is interrupted, the flicker is stopped through the discriminating processing. After a prescribed time passes after interruption or when the manual operation of other operation edge is started, the frame is vanished. The operation edge and others can be classified and the misoperation can be immediately found.

Filed: 1982-10-20
Abstract: PURPOSE:To eliminate a part, where a bonding agent beneath a light shielding region is not hardened, by limiting the width of the light shielding region of a color separating filter to a specified value or less, thereby providing sufficient diffraction from the transmitting region of ultraviolet rays and the amount of intrusion from the surrounding part. CONSTITUTION:A color separating filter 1 has a light shielding region 3 made of chromium, whose width is 1.5mm. or less, at the surrounding part of the filter 1. A stripe shaped pattern 2 is formed in the light shielding region 3. A solid state image pickup element 4 is of, e.g., a frame transfer type, and has a light receiving part 5, an accumulating part 6, and a bonding pad 7. The solid state image pickup element and the color separating filter are set in a sticking device, and an ultraviolet ray hardening type bonding agent 8 is dropped on the light receiving part 5 of the solid state image pickup element 4. Thereafter, the solid state image pickup element 4 is compressed to the color separating filter 1, and their positions are aligned. Ultraviolet rays are emitted from the side of the color separating filter on the entire surface, and the ultraviolet ray hardening type bonding agent is hardened. Thus, the bonding agent at the part beneath the light shielding region made of chromium can be perfectly hardened, and highly reliable bonding can be performed.
