Using a silicon single crystal with (100) plane orientation as a base material, a pectinate portion having a slope portion and a patterning material guiding groove is formed through photolithography process. A liquid reservoir for keeping a patterning material common to tooth portions of the pectinate portion is formed in the same step as a step for forming the guiding grooves. In forming slope portion, anisotropic wet etching allows easy and accurate formation of a slope portion with (111) plane orientation to (100) plane orientation, by taking advantage of differences in speed due to the plane orientations. In addition, by forming a groove portion using anisotropic dry etching, the patterning material guiding groove having a perpendicular sidewall reaching the slope portion may be formed at high accuracy. A pattern forming apparatus with high accuracy and low cost is provided.

A panel (1) for a plasma display includes a substrate (2). Linear first ribs (31) each extending in the y direction are arranged in the x direction perpendicular to the y direction on a main surface of the substrate (2) at a predetermined pitch. Linear second ribs (32) each extending in the x direction are arranged in the y direction on the main surface of the substrate (2) at a predetermined pitch. A clearance (4) exists between each of the second ribs (32) and the substrate (2) in a space formed by two adjacent ones of the first ribs (31). Two adjacent cells arranged in the y direction are continuous through the clearance (4). Thus, it is possible to supply a light emitting material, and feed gas necessary for light emission, to each cell using the clearance (4) in a suitable manner in the panel (1).

In a method and an apparatus for manufacturing a semiconductor integrated circuit, including a wafer test process, an assembling process and a sorting process, electric characteristics of a plurality of semiconductor integrated circuits formed on a wafer, is measured, and then stored in a memory means together with data of the position of each semiconductor integrated circuit. The plurality of semiconductor integrated circuits on the wafer are cut into individual semiconductor integrated circuit chips. On the basis of the position data and the electric characteristics of each of the semiconductor integrated circuit chips read from the memory means, the semiconductor integrated circuit chips are classified into at least two subsets each consisting of non-defective semiconductor integrated circuit chips having the same electric characteristics different from that of products included in the other subset, and the non-defective semiconductor integrated circuit chips included in each of the at least two subsets, are packaged for each of the at least two subsets, so that the sorting is simultaneously carried out.

A gate valve has a valve rod equipped with a valve plate having a pair of valve plate surfaces, wherein the valve rod is tilted by an actuator to thereby effect highly reliable valve opening/closing operation with a simple construction. In the gate valve, the valve rod, which is equipped with the valve plate with the pair of valve plate surfaces, is rotatably supported, and raised and lowered by a raising/lowering cylinder, the valve rod being tilted by an actuator, a combination of a cam member and a cam raising/lowering cylinder, a combination of a driving block and a cylinder, or a combination of a connection member and a driving device (not shown) to thereby effect valve opening/closing with the pair of valve plate surfaces.

A film dissolving liquid is ejected from a needle-shaped nozzle onto a peripheral edge portion of a substrate surface of a SOG film, while being subjected to the film dissolving liquid. The substrate is rotated in order to dissolve and remove the SOG film from the peripheral edge portion of the substrate. The film dissolving liquid is a solvent or mixture of two or more solvents selected from the group cyclohexanone, .gamma.-butyrolactone, ethyl lactate or ethyl pyruvate. As a result, a swelling of the SOG film is not created at the edge portion of the substrate. A crack is not therefore created at the edge portion of the SOG film, and generation of particles due to a damage at the film swelling portion thereof is prevented.

A dispensing apparatus for delivering a silica coating solution in a fixed quantity from a liquid container to a surface of a substrate to form a silica film thereon. The liquid container storing the silica coating solution is connected to a diaphragm pump through a suction pipe. The diaphragm pump is connected to a nozzle through a delivery pipe. The coating solution in the liquid container is supplied to the nozzle by sucking and delivering action of the diaphragm pump. The coating solution is discharged from the nozzle to a surface of a substrate supported by a spin chuck of a spin coating apparatus.

A pattern forming apparatus (1) comprises an ejection part (41) for ejecting a patterning material to a main surface of a substrate (9) from a plurality of outlets. The ejection part (41) moves relative to the substrate (9) in a direction along the main surface of the substrate (9) by a stage moving mechanism (2) and a plurality of linear pattern elements are formed on the substrate (9). In forming the linear pattern elements, moving speed of the plurality of outlets relative to the substrate (9) is changed periodically by an outlets moving mechanism (44) and gnarl portions each of which spreads in a direction perpendicular to a direction extending the linear pattern elements (91) are formed in each linear pattern element (91). This makes it possible to form a pattern similar to parallel crosses on the substrate 9 appropriately while ejecting the patterning material from the plurality of outlets.
