Title: Manufacture of semiconductor device
Inventor: MORINAGA MASATOSHI
IPC: H01L21/306
Filed: 1990-05-28
Abstract: PURPOSE:To enable detection of an end point of etching and to prevent a contact fault of a minute electrode window by using a monitor pattern having a line of the same width with a minute pattern and having a pattern of a large area corresponding to the width of a scribe line on the opposite sides, and by detecting a time point when the inside of the pattern changes from hydrophilic nature to water-repellent on the occasion of wet etching. CONSTITUTION:On the occasion when an opening 3 is formed in an insulating film 2 on a semiconductor substrate 1 by wet etching, a mask 4 of a resist or the like which has an opening of a monitor pattern 7 prepared by connecting patterns 6 of a large width to the opposite side of a minute line-shaped pattern 5 is used. This is aimed to remove speedily an etching liquid in the line-shaped pattern 5 into the patterns 6 of the large width on the opposite sides by a suction effect by a capillary phenomenon, at the time point of completion of reaction when the Si substrate is exposed and becomes water-repellent. The line to be regarded as showing an end point of etching for its water repellency is determined beforehand by a test, and the etching is stopped at the time point when the prescribed line becomes water-repellent.

IPC: B41J29/20
Filed: 1993-06-08
Abstract: PURPOSE: To provide a method and apparatus for preliminarily investigating the exhaustion state of the ink in the storage part of an ink jet printing head. CONSTITUTION: The pulses corresponding to bits to be printed are serially sent to a counter 54 from a printing bit generator 50 to be counted. Each of the pulses corresponds to one ink liquid droplet discharged from each of the nozzles of a printing head 33. The number (m) of ink liquid droplets equal to the amt. of ink evaporated from a cartridge 15 within a prescribed time and the number N of ink liquid droplets discharged from the printing head equal to the ink amt. held within a storage part are stored in a memory 56. A clock circuit 58 sends one pulse to a central processor 45 at each time when the prescribed time is elapsed to send the number (m) of ink liquid droplets to an addition circuit 60 on the basis of the pulse. When the sum (m+Px) thereof is equal to N, a comparator 65 energizes a display circuit 67 to issue an alarm for the replacement of an ink cartridge.

IPC: G06F11/22
Filed: 1988-06-03
Abstract: PURPOSE:To effectively conduct the test of the function of a collision supervisory circuit among respective terminal equipments by inverting subsequent channel bits and returning them to a line when a signal channel is received and coincidence with a specified character pattern is detected. CONSTITUTION:The specified character pattern is integrated in the signal channel D bit of a frame which is transmitted from a line connection part 2-12 to the line 3 and is transmitted. When a line connection part 1-12 receives the character pattern and a comparator 23 detects coincidence with a setting pattern, an inversion circuit 22 inverts the subsequent channel D bits, integrates them in the frame as an echo channel E and returns them to the line 3. The connection part 2-12 receives them, compares a transmission channel D with the channel E in correspondence with bits, detects noncoincidence from timing subsequent to the number of setting bits, recognizes the abnormality of the frame, namely, a collision phenomenon and stops the transmission of the channel D. Thus, the normalcy of the collision supervisory circuit of the connection part 2-12 can be tested and recognized by optical timing.
