Title: Method of manufacturing a Schottky diode device
Inventor: SUGITA NAOMASA C O INTELLECTUA
IPC: H01L29/872
Filed: 1990-12-14
Abstract: A Schottky diode device can be fabricated by forming a positive resist layer (24) on an insulating layer (23) formed on N type substrate (22), and patterning the resist layer (24). The pattern in the resist includes (i) a first isolation region-defining annular open pattern (25) defining therewithin a device-forming region (DR) having a predetermined size, (ii) a second isolation region-defining open pattern (26) dividing the device-forming region (DR) into a plurality of unit regions (UR) each having a maximum size defined to be 500 µm or less, and (iii) a plurality of individual openings (27) having a size of 1 µm or less and arranged at a predetermined pitch in each of the unit regions (UR). The patterned resist (24) is used to pattern the insulating layer (23), and P type impurity regions (28, 29, 30) including individual regions are formed using the patterned insulating layer (23) as a mask. After removing the insulating layer (23), a barrier metal (31) is formed forms Schottky barrier diodes with the individual P type impurity regions (28, 29, 30) and connect them in parallel.

Title: Apparatus and method for digital halftoning.
Inventor: SURBROOK CRAIG LOUIS
IPC: H04N1/405
Filed: 1989-11-08
Abstract: Disclosed are apparatus and methods for producing halftone screens (color separations) from continuous tone intensity signals that are supplied by an optical scanner (12) and are stored in memory (18-2, 18-3, 18-4 and 18-5) such that the memory addresses correspond to the Cartesian coordinates of the picture elements produced by the optical scanner. A digital signal processor (10) processes the stored continuous tone intensity values on a row-by-row basis with the memory elements in each row being sequentially accessed column-by-column. The memory addresses of the accessed continuous tone intensity signals are processed using an incremental addressing method that transforms the memory address into dither element column and row indices of a dither matrix (FIG. 4) that is used to produce the halftone dots of each halftone screen. The screen angle and the screen ruling of the halftone screens are selectively controlled and established by the incremental addressing method in view of the dither matrix and digital data output device being employed by the system. This allows the system operator to produce sets of halftone screens (e.g., the yellow, cyan and magenta color separations used in conventional four-color halftone printing) in which each each color separation exhibits the conventional screen angle and the screen ruling is established at a value that is appropriate for the color printing process to be employed.

Abstract: L'invention concerne un procédé et un appareil de coulage de gels à gradients, sans vides, dans des structures de support confinées telles que des configurations du type plaque mince. En outre, par l'utilisation d'un plan d'activation différentiel pour le coulage, le procédé permet de produire lesdits gels dans des plaques de dimension capillaire en coupe transversale. Selon un procédé préféré, on coule un gel de plaque à gradient par remplissage d'un nombre de gorges (95) pouvant être compté, dans une première plaque (89) avec un premier liquide de gélification. On forme une région de coulage de gel pour un gel de plaque, en espaçant ladite première plaque (89) d'une seconde plaque (87), de manière à ménager un passage d'écoulement entre lesdites première et seconde plaques ayant une composante directionnelle orthogonale par rapport auxdites gorges (95). On injecte un second liquide de gélification dans la région de coulage du gel, entre les plaques, de sorte que ledit premier liquide se mélange audit second liquide à mesure que le second rencontre chaque gorge, formant ainsi un mélange de gélification présentant un gradient de composition. On provoque ensuite la gélification dudit mélange de gélification dans la région de coulage du gel, formant ainsi un gel de plaque à gradient.
