Title: Formation of resist pattern
Inventor: SUZUKI TAKESHI
IPC: H05K3/06
Filed: 1980-05-19
Abstract: PURPOSE:To obtain a submicron resist pattern by controlling exposure to diffracted ultraviolet rays by making use of the fact that the intensity of ultraviolet rays straightly passing through a photoresist film is higher then that of diffracted ultraviolet rays. CONSTITUTION:When a photoresist film 2 is formed on the principal face of a semiconductor 1, exposed to ultraviolet rays UV through a photomask pattern 3a, and developed to manufacture a resist pattern, the resulting pattern is made larger than the pattern 3a by width (m) owing to the diffraction of ultraviolet rays. This width (m) is in inverse proportion to the wavelength lambda of ultraviolet rays and the width M of the mask pattern 3a, and it is in proportion to the thickness L of the film 2. For example, a photoresist film, ''AZ1350 '' of SHIPLEY Co. U.S.A. is formed in 0.2+ or -0.05mum thickness, and in case of a 0.5-0.7mum mask pattern 3a, the film is exposed for 27-35sec and developed for 5-7sec at 30- 35 deg.C. Thus, by choosing exposure conditions, developing time and temp. according to the resist film, width (m) is made smaller, and a 0.5-1mum wide resist pattern of high accuracy is obtd.

Filed: 1994-03-10
Abstract: PURPOSE:To provide a semiconductor device, which suppresses the lattice defects in a board by lessening the cells implanted into ROM, and a write-in method by which the write in of data is easy. CONSTITUTION:A mask ROM, which outputs data of either '1' or '0', is equipped with an output control means which decides whether to output data after inverting them or output them as they are, according to the data that a cell array 10 has. In case of using user data which abound with '1' or '0' data being decided by performing implantation into ROM, the data inversion is performed by an output control means, and in the case of using user data which abounds with data being made without performing implantation into ROM, the data inversion is not performed. The memory cells in a cell array being implanted into ROM regardless of the content of the user data by an output means are lessened. The ion implantation into a MOS transistor, which breaks the path of the output control means, is performed at the same time with the ROM implantation into a memory cell.

Filed: 1989-03-20
Abstract: PURPOSE:To maintain a head always in an optimum state by providing a prescribed time to monitor the timing for cleaning and outputting a head cleaning instruction signal when the time exceeds the specified time. CONSTITUTION:The timer TM 1 operates in proportion to the speed of the oscillation frequency of an oscillator OSC set by a volume control VR for setting environmental conditions during a reading and writing operation to a floppy disk, etc. When timer interlock switches SW 1, SW 2 set at two stages exceed the respective set time, the timer operates to light a head cleaning notice lamp LP 1 and the head cleaning instruction lamp LP 2, thus giving an instruction to a user. The timer TM is initialized when a head cleaning end manual switch SW 3 is reset upon ending of the head cleaning. The switches SW 1 and SW 2 are then returned to the initial positions to put out the lamps LP 1 and LP 2. The degree of contamination of the head by the use frequencies and environmental conditions is adequately detected in this way and the head is maintained always in the optimum condition.

Abstract: PURPOSE:To obtain a scanning circuit having a high degree of integration and high performance and a photoelectric conversion section having high photo- sensitivity by forming an optoelectric transducer into an impurity layer lower in concentration than an impurity layer to which a scanning means is provided. CONSTITUTION:A scanning circuit section (A-A' section) is formed in CMOS structure composed of an N channel MOS transistor and a P channel MOS transistor. Each transistor is shaped in a P-type well 22 and an N-type well 23 in concentration higher than a P substrate 21. On the other hand, a photoelectric conversion section (B-B' section) is formed in the P-substrate 21 in low concentration. Accordingly, the degree of integration is easily improved by using a micro-transistor because the scanning circuit section (A-A' section) is formed into a high concentration impurity layer, and high photo sensitivity is acquired because the photoelectric conversion section is shaped onto the low-concentration substrate.
