Title: Flattening method
Inventor: NAGASAWA SHUICHI
IPC: H01L21/302
Filed: 1988-04-12
Abstract: PURPOSE:To perform flattening uniformly with respect to a flattened pattern having an arbitrary size, by covering the whole face of the pattern to be flattened at the minimum extent; besides, by forming a stencil pattern consisting of a resist which possesses an overhang structure at its upper part and then forming an insulating film pattern having the same film thickness as that of the flattened pattern at a part other than the flattened pattern without damaging specially the flattened pattern. CONSTITUTION:A stencil pattern possessing an overhang structure at its upper part which is formed in such a manner that pattern to be flattened, that is, an electrodes pattern 1 is perfectly covered at the minimum size of the overhang structure is formed with resist. In the after-processes, the pattern to be flattened does not suffer damage from chemicals with the exception of an organic solvent. After forming the first insulating film layer 3 having a film thickness that is almost equal to that of the pattern to be flattened on the whole surface of a substrate, the stencil pattern and an insulating film layer which is formed on the above stencil pattern are removed and then, an insulating film pattern having the film thickness that is almost equal to that of the pattern to be flattened is formed at an interval which is formed between the patterns to be flattened through a groove having a constant width. With respect to etchback, each pattern to be flattened having an arbitrary size is in existence. Yet in the case of the actual pattern to be flattened, it is always converted into the pattern of the groove having the constant width. This situation eliminates the need for depending upon a pattern width and makes it possible to perform etchback uniformly.

Title: Film carrier
IPC: H05K1/00
Filed: 1992-03-16
Abstract: PURPOSE:To prevent disconnection, cracks, and deformation like twist and bending when a conductor pattern is bent, and form the conductor pattern of a bending part with freedom, by arranging a plurality of small holes on an insulative film of the bending part. CONSTITUTION:An insulative film 2 wherein a plurality of small holes 5 are punched is used. When a film carrier is bent, the whole bent part forms a gentle arc, so that the bending stress is dispersed throughout the whole hole area 2a for bending work, and generation of cracks in a lead or the like is prevented. The small holes are not always punched in a lattice type, but a zigzag type or the like may be arbitrarily used. The bending radius can be adjusted by selecting small hole working pitches p1, p2, the small hole diameter (d), etc. Since a conductor pattern 1 is retained by the insulative film punched in a lattice type, short-circuit is not generated when the conductor pattern 1 is obliquely drawn. Hence the freedom of conductor pattern formation is increased.

Title: Position detector
Inventor: EBIHARA MASAYUKI
IPC: G01D5/245
Filed: 1980-07-01
Abstract: PURPOSE:To obtain an inexpensive position detector by detecting signals from a pair of detectors and their phase difference and switching the method of pulse generation in a count pulse generator. CONSTITUTION:Position detectors DA and DB generate pulses with phase difference each other when an object to be detected is moved. A count pulse generator 4 receives the outputs of both detectors and sent a forward (UP) or backward (DOWN) count pulse to a counter 5. When the detector DB is off-failure, for example, a detecting circuit 1 outputs a signal AY to indicate the rising of a signal A to the rising of a signal B. An abnormal circuit 2 receives signals AY and A and sends a B failure detecting signal to an abnormal circuit 3 to output a signal BZ to a pulse generator 4. After receiving signals BZ and A, the pulse generator 4 sends a count pulse for UP or DOWN to the counter 5. Thus, since a pair of detectors complete a series of operation, the inexpensive position detectors can be obtained.
