The stroke table is provided for recording the parameter data of each stroke. The graphic drawing program is provided for displaying the dot-matrix pattern of a font on the screen based on the character table and the stroke table. When drawing a font in a dot-matrix frame, the graphic drawing program first searches the character table to find the stroke codes of all strokes of the character and the address of each stroke in the frame according to the word code of the font. Then, based on the stroke code of each stroke, the stroke table is searched to find the dot-matrix pattern data of each stroke. Finally, based on the address and dot-matrix pattern data, the dot matrix pattern of each stroke is drawn on the dot-matrix frame, thereby forming a dot-matrix pattern for the font.

Filed: 1998-10-19
Granted: 2000-08-11
Abstract: An interlayer insulation film is deposited on a substrate in which a semiconductor element has been formed. A wiring groove is formed in the interlayer insulation film. A barrier layer, made of a material which prevents the diffusion of Cu atoms, is formed on at least the inner surface of the wiring groove and the upper surface of the interlayer insulation film. A seed layer, made of Cu which contains an impurity, is deposited on the barrier layer. By way of plating, a conductive layer made of Cu is deposited on the seed layer so as to fill the wiring groove. The substrate is heated to precipitate the impurity contained in the seed layer, on at least an interface between the seed layer and the barrier layer. The conductive layer, the seed layer and the barrier layer are removed until the upper surface of the interlayer insulation film appears, thus performing surface planarization. A method for forming a Cu wiring whose adhesion to the underlying surface is high and whose electromigration resistance is excellent, is attained employing a plating process.

Title: Trapping fleas with virtual living environment and the apparatus therefor
Inventor: HUANG JI-JIN
IPC: A01M1/02
Filed: 1998-11-27
Granted: 1999-08-01
Abstract: This is a type of flea trapper that makes use of virtual living environment consisting of desirable fragrance, light and temperature to emulate the virtual living environment of fleas. It lures fleas to misbelieve that the body of a human being or an animal is close by, so fleas come out and cluster at the preset location for extermination. The said apparatus is a cage-like case which includes a container at its base for holding absorbent material like cotton soaked in drops of solution, thereby the cotton material emits the desirable fragrance once the electric heater is turned on, together with the light effect from the light emitter. Fleas are lured to enter the case that are preset with an electric net or adhesive lined absorbent material, so that they can be easily exterminated in large numbers without too much trouble.

Title: Fabrication method of crown capacitor structure
Inventor: LI YU-HUA
IPC: H01L27/108
Filed: 1999-06-10
Granted: 2000-12-11
Abstract: The invention discloses a method applied to manufacture the crown capacitor structure in DRAM, and particularly, a planarization method to improve the Inter Layer Dielectric (ILD) material on the crown capacitor structure. There is a large difference between the capacitor structure and periphery circuit region after the fabrication of the conventional crown capacitor structure. This will cause a severe thickness difference while proceeding planarization process of ILD formed afterwards, and further affect accuracy of the subsequent fabrication and lower the yield rate of product. Prior to the fabrication of the crown capacitor structure, the invention utilizes a dielectric layer to lift up the periphery circuit region. Therefore, the height difference between the capacitor structure and the periphery circuit region is not too large after the fabrication of the crown capacitor structure. As such, it is applicable to provide excellent planarization fabrication process carried out for ILD material to improve the conventional issue in fabricating the crown capacitor structure.
