Title: Manufacture of shadow mask
Inventor: OOTAKE YASUHISA
IPC: H01J29/07
Filed: 1983-04-15
Abstract: PURPOSE:To contrive to decrease cost without degrading of a shadow mask, by separately removing resistance and photosensitive film layers formed during the manufacture of a shadow mask, recovering the removed resistance substance, and repeatedly using it. CONSTITUTION:Etching is performed through the small hole of one photosensitive film layer 2a provided on the surface of a material to form a shallow cavity, and then a resistance layer 6 is formed. Then, etching is performed through the larger hole 3b of the other photosensitive film layer 2b to form a cavity 5b reaching the resistance layer 6. This material is sequentially sent through a washing tank 21 to a spray chamber 23 and a vapor chamber 24 to remove the resistance substance and then further sent to a chamber 25 for removing a photosensitive film layer. A liquid used for stripping the resistance substance in the spray chamber 23 is recovered in a tank 28 and reused in the spray chamber 23. When the efficiency of separate dissolution is lowered, the deteriorated liquid is recovered in a conditioner tank 30 to which a new stripping liquid is supplemented through a pipe 291. Hereon, the same operation is performed in the vapor chamber 24, too.

Title: Thin film diode and manufacture thereof
Inventor: TOGASHI SEIGO
IPC: G02F1/136
Filed: 1994-03-10
Abstract: PURPOSE:To enable a thin film diode to be lessened in capacitance and easily manufactured by a method wherein a semiconductor layer is provided onto a first electrode layer deposited on a substrate, a second electrode layer is provided onto a buffer layer deposited on the semiconductor layer, and the semiconductor layer and the buffer layer are patterned into nearly the same shape. CONSTITUTION:A buffer layer 553 is provided between a semiconductor layer 543 deposited on a first electrode layer 413 and a second electrode layer 463. For instance, provided that the second electrode layer 463 is formed of Al, and the semiconductor layer 543 is formed of amorphous Si, the buffer layer 553 of Cr is formed as thick as 100nm so as to effectively prevent mutual diffusion in an after process. At this point, the buffer layer 553 is patterned after the same pattern with the semiconductor layer 543, so that only a film forming process through which the buffer layer 553 is formed is additionally provided to realize a thin film diode of this constitution without changing processes much.

Title: Holder for measuring semiconductor
Inventor: HASEGAWA TAIJI
IPC: G01R31/26
Filed: 1982-04-21
Abstract: PURPOSE:To enable the withstanding property against pressure applied during the measurement to extend the life thereof by assembling a holder with a metal block through an insulation member so that the holder can be worked at a high accuracy despite any complicated shape thereof while holding a semiconductor sucked under a vacuum pressure. CONSTITUTION:When placed on a holder, a semiconductor 9 is held sucked under a vacuum pressure with a semiconductor surrounding resin section fitted into a hole 10 through a pipe 14 and through holes 11' and 11 and three lead terminals are brought into contact tight with metal blocks 1-3 respectively. Then, a measuring contactor 15 comes down and contacts the lead terminals of the semiconductor 9 to measure. At this point, metal blocks 1-3 receive a pressure applied on the lead terminals from the measuring contactors 15 thereby increasing the durability of the holder. Such suction holding of the semiconductor under the vacuum pressure prevents the floating thereof due to vibration or the like generated with the movement of the holder or enables the semiconductor to withstand an uneven pressure of a force applied by the lead terminals of the measuring contactor. The vacuum pressure can be set at a proper value.

Title: Information recording medium regulating device
Inventor: KOIKE MAKOTO
IPC: G11B17/34
Filed: 1985-03-29
Abstract: PURPOSE:To make an information recording medium contact a head means in optimum state with sliding by providing a regulating body having a pair of regulating parts at the upstream and downstream sides of the head means and a second regulating body at the upstream side. CONSTITUTION:Pressure contact is controlled by two regulating parts 310, 320 of an upper pad 300 so that a recording surface 110 of a magnetic disk 100 is in optimum sliding contact with a head gap part 210 of a magnetic head 200. When the magnetic disk 100 is driven into rotation at a faster speed (for example, 3,600rpm) in the direction shown, the vibrations are produced in the magnetic disk 100 in which the main component is perpendicular to the main surface so that the recording and reproducing characteristics are markedly deteriorated. However, because the lower pad 400 is provided, the above vibrations are effectively suppressed by the regulating part 410. Therefore, during high speed rotation of the magnetic disk 100, an optimum sliding contact between the magnetic disk 100 and the magnetic disk 200 is maintained at all times to assure an optimum recording and reproducing properties.

Title: Method of dry etching silicon nitride film
Inventor: NIIMURA TADASHI
IPC: H01L21/3065
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To enable selective etching of a SiN film by increasing the selection ratio between a silicon nitride film and another material by a method, wherein a gas species is composed of a mixture of a gas containing fluorine and oxygen gas doped with a hydrogen gas. SOLUTION: A silicon nitride film (SiN film) on a substrate is dry etched away by an activated specie of gas in the composition of a mixture gas of a fluorine containing gas and an oxygen gas doped with hydrogen gas, thereby enabling the SiN film to be selectively etched away from a material underneath, etc. That is, the selective etching action of the SiN film from the other material film accelerates the etching rate only of the SiN by the hydrogen atoms produced in the plasma extracting the nitrogen from the SiN film or destructing the structure of the SiN. As a result, the etching ratio between the SiN and the other material can be increased, thereby enabling the SiN film to be selectively etched with respect to other material films.

Title: Optical printer
Inventor: ITOU OSAMU
IPC: G02F1/05
Filed: 1982-04-20
Abstract: PURPOSE:To obtain an optical printer of simple constitution which has high resolution by setting the scanning-directional effective length of the optical shutter area of an optical shutter element less than minimum scanning-directional record length. CONSTITUTION:The optical shutter element 34 consists of electric ceramics 24, an electrode 25, two polarizing plates 26 and 27 having axes of polarization crossing with each other at right angles, and a light shielding plate 28 for limiting the length of the optical shutter area in the scanning direction F to width (b). The direction of light incidence is shown by D. Light from a light source 29 is passed through the optical shutter element 34 and focused on a photoreceptor moving in a direction G through an image-forming lens 36. For recording of minimum record length rm in the scanning direction, when b=rmin/m for the effective length bm of the optical shutter where (m) is the image-formation magnification of the image-forming lens, the photoreceptor 23 moves continuously, but the optical shutter 34 is operated in an extremely short time. When b<rm/m, it is unnecessary to operate the optical shutter in the short time. The printer has high resolution because no cylindrical lens is used.
