Title: Pattern forming method for photosensitive polyimide film
Inventor: NAKAGAMI YOSHIMASA
IPC: H01L21/312
Filed: 1990-03-26
Abstract: PURPOSE:To form a pattern precisely by a method wherein, after a photosensitive polyimide film is spread on a substrate to be processed, temperature gradient in the film thickness direction is so made that the temperature of the film in the vicinity of the substrate interface is higher than the upper layer part, pre-baking is performed, and then exposure and development are performed. CONSTITUTION:High temperature hot plates 1 and low temperature hot plates 2 are alternately arranged. The plates 1 are kept at a temperature wherein photosensitive functional groups added to polyimide precursor decompose. The plates 2 are kept at a low temperature, e.g. normal temperature. A rail 3 is lifted at a specified time, and moved in the arrow direction. Thereon an Si substrate 4 is so arranged that the spread film faces upward. While the rear is suitably vacuum-sucked, the substrate is moved, and the interface side temperature of the spread film for the substrate is increased, thereby decomposing the photosensitive functional groups whose heat resistance is inferior. When selective exposure is performed after the above baking process, crosslinked polymerization is generated on the surface side of the spread film, because photosensitive groups exist. Crosslinked polymerization, however, is not generated on the substrate side. The gradient of crosslinking density is generated in the spread film, so that the lower part can be easily dissolved by developer.

Title: Decimal arithmetic circuit
Inventor: NISHIBE SHINJI
IPC: G06F7/544
Filed: 1983-04-30
Abstract: PURPOSE:To ensure high-speed decimal arithmetic processing even in a recomplement mode by carrying out a 2nd-1st operand operation in parallel to a 1st-end operand main operation. CONSTITUTION:Two operands to be calculated are stored in A-REG13 and B- REG14 respectively. Then the 1st operator 15 performs a 1st-2nd operand operation; while the 2nd operator 16 performs a 2nd-1st operand operation respectively. The results of these operations are fed to a selector 19 via C-REG17 and D- REG18, and the contents of either one of both registers are selected. That is, the contents of the REG17 are selected if the result of the operator 15 is positive; while the contents of the REG18 are selected if the result of the operator 15 is negative. This selected data is written to a main memory 11 to finish the operation for an arithmetic instruction. As a result, the decimal arithmetic processing is executed at a high speed with no deterioration of the processing performance even in a recomplement mode.

Filed: 1987-03-30
Abstract: PURPOSE:To reduce the adverse effect to the device characteristics by setting the whole of a water to a temperature lower than the recrystallization temperature, and thereafter sequentially setting the whole wafer to a temperature higher than the recrystallization temperature while maintaining a predetermined temperature gradient in the wafer plane. CONSTITUTION:A wafer 20 is placed in a furnace 10 having a temperature gradient from 600 to 1500 deg.C in parallel with the temperature gradient. At this time, the high temperature end alpha1 of the wafer 20 near a furnace entrance 11 is set to 560 deg.C which is lower than 600 deg.C, the recrystallization temperature of amorphous silicon. When the temperature in the furnace 10 is increased to 1200 deg.C, the high temperature end alpha1 exceeds 600 deg.C first, the amorphous silicon of this part is recrystallized to generate a crystal core. Further, the neighborhood of the part in which the crystal core has occurred exceeds the recrystallization temperature, whereby the neighborhood part is recrystallized. Similarly, the portion exceeding the recrystallization temperature sequentially moves, and eventually the amorphous silicon of the whole water surface is recrystallized.

Title: Document converter and its method
Inventor: SAKAMOTO MORIHIRO
IPC: G06F17/28
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To provide such a device and method as outputs even a document file described by a character code, which is not handled at a computer system, without the erroneous characters. SOLUTION: A document file is taken in from an input part 1 and information of a character code normally outputted by a computer is obtained from an environmental information obtaining part 2. Then, the presence/absence of the necessity of a document file is judged by a control part 3. When the presence of necessity is judged, a reading converting part 4 converts reading to a character string expressing reading and a code system conversion part 5 converts the code. Thereby even when the document is not outputted perfectly, the 'second best means' of outputting only the reading of the document can be executed.

Filed: 1988-03-29
Abstract: PURPOSE:To exclude a collector-base junction capacity which does not perform a transistor function, and to improve high frequency characteristic by burying an oxide film in a semiconductor substrate of a high frequency transistor. CONSTITUTION:After an n-type epitaxial layer 1B is formed on an n<+> type silicon substrate 1A, the layer 1B is thermally oxidized to form a silicon oxide film, part of which is removed by etching to form a buried oxide film 2. Then, after an n-type epitaxial layer 3 is formed on the oxide 2 and the layer 1B, p-type impurity ions are implanted to form a p-type active base region 4. After a silicon oxide film 5 is then again formed on the surface, an opening 8E and an opening 8B are formed. Then, after an n<+> type polycrystalline silicon layer 6 and a nitride film 7 are formed, the opening 8E, the film 7 of the peripheral edge of the opening and the layer 6 are sequentially removed by etching, and the surface of the base region is exposed. Thereafter, a base contact is diffused in the opening 8B to form a region 9 and a region 10, and the region 4 is simultaneously made to arrive at the film 2. Subsequently, the film 7 is entirely removed by etching, and electrodes E and B are shaped and isolated. Thus, the device is obtained whose collector-base junction capacity is small, and whose high frequency characteristic is good.
