Title: Electrochemical machining method for deformed hole
Inventor: FUTAMURA SHOJI
IPC: B23H3/04
Filed: 2000-09-25
Abstract: PROBLEM TO BE SOLVED: To provide an electrochemical machining method that can precisely and efficiently machine a deformed hole with different cross-sectional inside contour dimensions along axial positions. SOLUTION: The electrochemical machining method for a deformed hole leads electrolyte in an electrode in the form of a hollow pipe comprising a core pipe of conductive material whose outer surface has a coating of insulating material and sprays the electrolyte from the point of the electrode, and applies voltage between the electrode and a workpiece of metallic material via the electrolyte, while moving the electrode axially relatively to the workpiece, to thereby machine a hole with different cross-sectional inside contour dimensions along axial places on the electrode.  The first step machines a hole with a uniform cross-sectional inside contour dimension along axial places on the electrode, and a subsequent step uses an electrode whose outer surface coating is partly removed to expose the surface of the core pipe of conductive material, to machine part of the hole machined in the preceding step.

IPC: C08L25/18
Filed: 2000-09-27
Abstract: PROBLEM TO BE SOLVED: To provide a resist material excellent in resolving power and dry etching resistance in exposure with EB(electron beam), EUV(extreme-ultraviolet radiation) or X-rays. SOLUTION: The resist material contains a polymer having repeating units each containing a naphthalene ring having one or more hydroxy groups represented by formula (1) ( where R1 is H, a 1-20C linear, branched or cyclic alkyl or a 6-20C aryl and (a) is an integer of 1-5) and repeating units each having a group obtained by substituting an acid-labile group for the hydrogen atom of the hydroxyl group of a carboxyl group. Since the resist material is excellent in stability when allowed to stand in vacuum after exposure with electron beams, causes slight trailing on a Cr substrate and is excellent in sensitivity, resolution and plasma etching resistance, it is suitable for use as a fine pattern forming material particularly in mask substrate working.

Title: Structure and method for sealing semiconductor component therefor
Inventor: OKURA HIDEAKI
IPC: H01L21/60
Filed: 2000-10-11
Abstract: PROBLEM TO BE SOLVED: To provide a sealing structure for a semiconductor component with improved reliability by applying a resin to only the peripheral part of a semiconductor package. SOLUTION: The resin is applied to only the peripheral part of the semiconductor component generating a high thermal stress without underfilling the resin. Durability in the connection of the semiconductor can be enhanced by reinforcing the peripheral part. The larger the amount of the resin to be applied is, the more the reliability is improved, and reliability comes closer to the reliability level of an underfill state. Also, the advantage of this method is that sealing in a short time can be realized because there is no need to wait for the permeation of the resin. Furthermore, while a substrate must be heated to decrease the viscosity of the resin in a conventional method, the heating is not required because the permeation of the resin is not required in this method. Thus, the sealing can be realized inexpensively.
