PROBLEM TO BE SOLVED: To provide a pattern formation method that can realize highly accurate patterning even when the film is made of photosensitive resin or the like and is thick. SOLUTION: A first pattern 1 is formed on a substrate 3, and a layer 2 made of a material to be patterned is formed in the opening 4 of the first pattern 1, and then the first pattern 1 is removed to form a second pattern made of a material to be patterned. In this method, the first pattern 1 is preferably constituted such that it may be made of metal or photosensitive resin, and the material to be patterned may be organic or inorganic.

PROBLEM TO BE SOLVED: To provide a wiring substrate for mounting a semiconductor device which can realize a higher density and finer wiring to cope with the increase in the number of terminals of the semiconductor device and the tendency toward narrower pitches, and a narrower pitch of an external electrode to cope with a more compact and higher density system, and superior in mounting reliability. SOLUTION: The wiring substrate for mounting the semiconductor device comprises an insulating layer 6 composed of a single layer, wiring 8 formed on the upper surface of the insulating layer, electrodes 5 each of which is formed under the lower surface of the insulating layer so that at least the circumferential side of the upper end of the electrode is in contact with the insulating layer and at least the circumferential side of the lower end of the electrode is not in contact with the insulating layer while protruding its lower end from the lower surface of the insulating layer, vias 7 each of which is formed on the upper surface of the electrode in the insulating layer so as to conduct between the electrode and the wiring, and a supporting body 16 arranged on the surface of the insulating layer.

PROBLEM TO BE SOLVED: To make it possible to impart high hydrophilicity, excellent wearing feel and sufficient mechanical strength in combination to a contact lens by forming a carbon film to at least part of its surface. SOLUTION: The carbon film is formed to at least a portion of the contact lens. This carbon film exhibits a particularly excellent effect with the hard contact lens. The materials of the hard contact lens include polymethyl methacrylate, siloxanyl methacrylate, siloxanyl styrene or the materials prepared by compounding these materials with methyl methacrylate and fluoromethacrylate and further, polymer consisting of fumarate, etc. The carbon film is preferably formed at the circumferential edge portion and concave face portion of the lens, i.e., the surface in direct contact with the eyeballs. More preferably the carbon film is formed over the entire surface of the contact lens.
Abstract:
PURPOSE:To form a uniform thin film of a large area without leaving a gap on an insulating substrate by DC glow discharge plasma CVD with a simple device. CONSTITUTION:A thin conductor film 14 is formed on an insulating substrate 13 and the periphery of the resulting substrate 17 is coated with an annular conductor sheet 16. The inside of the sheet 16 and the top of the periphery of the film 14 are brought into linear contact with each other and the substrate 17 and the conductor sheet 16 are kept at the same electric potential so as to prevent the generation of arc. The desired thin film 15 is then formed on the substrate 17 by DC glow discharge plasma CVD.
