Title: Electron-beam lithography system and alignment method
Inventor: ICHIKAWA NATSUME
IPC: G03F7/20
Filed: 1999-09-29
Granted: 2002-05-11
Abstract: Disclosed are an electron-beam lithography system employing an optical mark detector and having a distance of movement, by which a stage must be moved, minimized, and an alignment method. The electron-beam lithography system consists mainly of an electro-optical column, a control unit, a stage moving mechanism, a mark detector, and at least two optical mark detectors. The electro-optical column accommodates an electron beam source, a converging unit for converging an electron beam output from the electron beam source, and a deflecting unit for deflecting the electron beam. The control unit controls the converging unit and deflecting unit. The stage moving mechanism moves a stage that holds a sample to which an electron beam is irradiated. The mark detector measures electrons reflected when a position detection mark inscribed on the sample or stage is scanned with an electron beam, and detects the position of the position detection mark from a signal of detected reflected electrons. The at least two optical mark detectors optically detect the position of a position detection mark.

Title: Four-axis motion control method and apparatus thereof
Inventor: WANG KUEN-CHUAN
IPC: G05B19/00
Filed: 2000-01-12
Granted: 2002-12-21
Abstract: The present invention relates to a four-axis motion control apparatus consisting of a motion control card, an industrial personal computer (IPC) and an input device. The IPC includes a motion control card and a digital input/output (I/O) card and the input device may either be a keyboard or an instruction box. Firstly, before inserting the motion control card into the IPC, the procedure to copy the driver of the motion control card into the index of one of the operation systems of the IPC should be carried out. Then, the driver and the default value of each hardware-related parameter should be set into the log-in file of the operation system for others, such as the driver and the application program, to use the parameters directly and complete the procedure to make hardware setting of two parameters, position and interrupt, of the motion control card on the IPC. After setting the hardware parameters and ensuring each required parameter has been loaded into the system log-in file, the motion control card should be inserted into the IPC and the IPC should be restarted. Then, the procedure to install the user interface under an index in the hard disc of the IPC should be carried out. The user interface is used for connecting the driver layer and the application program layer written by the user so that the user needs only to call the interface program bank to drive the motion control card. After completing the hardware parameter setting, the driver installation, the hardware installation, and the user interface installation of the motion control card and in cooperation with the IPC, the user may use the provided commands and the input device (either a keyboard or an instruction box) to develop the required application software. Since commands are provided, the user does not need to write any long low-level program language. Each program is written in steps and whether a step should be run is decided by the external input contact point. After a step is run, an output contact point may be selected as ""ON"". So, the user has the flexibility in planning the interaction between the machine itself and other external equipment (e.g. a conveyer belt). Through the digital I/O card of the IPC, signals generated by the operation of the motion control card are output to the peripherals of the next level for four-axis motion control. Since the user does not need to write any complicated low-level program language when commands and user interface are provided, not only the program writing time may be shortened but maintenance of the developed programs also becomes easier. Besides, program input, correction, and writing can be made in accordance with the requirements so that application software suitable for the machine can be developed quickly and four-axis motion control can be carried out easily.

Title: Method for producing a self decontaminating surface
Inventor: DIMARZIO DONALD
IPC: C23C4/10
Filed: 2000-02-29
Granted: 2002-05-21
Abstract: A method for producing a self decontaminating surface to decontaminate chemical and biological contaminants that are deposited on the surface and decontaminatable through reaction with free hydroxyl radicals. The method first includes determination of a surface to be treated and which is exposable to ultraviolet light. Second, a coating of nanoparticles of a transition metal oxide, non-limitedly exemplified by anatase titanium dioxide, is applied to the chosen surface. Application of the coating is accomplished by spraying heated nanoparticles or clusters thereof from a feed stock onto the surface to form a nanoparticle coating, with the nanoparticles being at a temperature of at least about 750 DEG C upon exit from a spray apparatus and of a size between about 5 nm and 100 nm. Finally, the treated surface is exposed to ultraviolet light and water moisture, either naturally from the environment or artifically, to thereby catalytically form free hydroxyl radicals that thereafter react with the contaminants to render them generally harmless.

Granted: 2001-10-11
Abstract: The present invention relates to a polycrystalline semiconductor thin film, its manufacturing method, a semiconductor device, a manufacturing method of the semiconductor device and an electron device. More particularly, it relates to effective technique of manufacturing an electronic device suitable for manufacturing transistors (thin film transistor, TFT) on the upper surface of the polycrystalline film, polycrystalline semiconductor thin film for manufacturing the TFT, and LCD device or information device assembled by the TFT. The object of the present invention is to provide technique to increase polysilicon grain size (grain diameter is more than 8 μm) uniformly oriented in a prescribed face orientation and to precisely control crystal grain positions. To achieve the object, by using anisotropric etching and mask, regular protrusions are formed on polysilicon film. The front end of the protrusion is formed by single crystalline formed by anisotropic etching to selectively leave a specific face orientation, so as to form an amorphous silicon crystallized growing core stacked thereon. In repeating such process for a plurality of times, the gap, size, and height of the protruded node increase larger until the diameter of the silicon crystal grain showing on the surface is increased to a desired size. Accordingly, it is able to form large-diameter silicon crystallized core uniformly oriented in a prescribed face orientation at precisely controlled positions. The transistors are respectively formed on each single crystalline silicon area with increased grain diameter.

Title: Bus hold circuit with overvoltage tolerance
Inventor: MORRILL DAVID P
IPC: H03K3/037
Filed: 2000-05-22
Granted: 2003-01-21
Abstract: A CMOS-based bus-hold circuit having overvoltage tolerance. The bus-hold circuit of the present invention includes, in addition to conventional input and latching inverters, a sense circuit and an arbiter circuit designed in combination to block overvoltage events from powering the latching inverter. The sense circuit includes a comparator designed to compare the potential of a standard high-potential power supply rail to the potential associated with a signal applied to the bus-hold circuit's input node. The higher of those two potentials is used to activate the arbiter circuit that in turn couples the higher of those two signals to a pseudo high-potential power rail. The pseudo high-potential power rail is used to supply power to the latching inverter such that the latching inverter will not be activated during overvoltage conditions, particularly when the circuit is in its high-impedance state. The bus-hold circuit may be similarly designed to establish an undervoltage tolerance as well.
