Abstract: PROBLEM TO BE SOLVED: To alleviate the stress in the tangent direction and simultaneously control generation of a stress in the thickness direction, by controlling anisotropic axis that provides the maximum anisotropic characteristic in the predetermined direction using a material showing anisotropic property of thermal stress for a resin layer provided for a passivation film. SOLUTION: After a passivation film 3 having the predetermined aperture 8 on a semiconductor element 1 is formed, this film is coated with a photosensitive polyimide varnish that becomes a first resin layer 4. Next, after a conductor wire 6 is formed, the water content absorbed by the first resin layer 4 is eliminated through a thermal treatment for two hours at 140 deg.C and a porous polyimide film (second resin layer 5, hole diameter is 0.5 μm or less) that is previously processed to the predetermined shape is pressed in close contact under the pressure of about 10 N/m at 230 deg.C.  Since this porous polyimide film has the through hole in the thickness direction (vacant hole rate is about 30%), anisotropic property is obtained for the stress in both tangent direction and thickness direction (elastic property rate in the thickness direction = 2.5 Gpa, line expansion coefficient in the thickness direction = about 40 ppm/ deg.C, elasticity coefficient in the tangent direction is 1.8 Gpa, line expansion coefficient in the tangent direction is about 100 ppm/ deg.C).

IPC: G02C13/00
Filed: 1988-05-27
Abstract: PURPOSE:To enhance oxygen permeability and to allow the long-time continuous wear of the contact lens by irradiating the contact lens after molding with a polyvalent heavy ion beam to form many pores. CONSTITUTION:The contact lens after molding is irradiated with the polyvalent heavy ion beam and is thereby formed with the many pores. The heavy ion beam to be used is generated from an ion irradiating device such as tandem type ion accelerator and ion species heavier than lithium ions are preferably used as the heavy ions in order to form the finer pores to the contact lens. The charge of the heavy ions are capable of forming the heavy ions of high energy such as pentavalent and heptavalent ions in which many electrons can be taken from the monovalent ions. The pores optimum as the oxygen permeable contact lens are formed by using such polyvalent heavy ion beam. The oxygen permeability is thereby enhanced and the long-term wearing is allowed.

Abstract: PURPOSE:To form a highly accurate gap having stable characteristics by using a core fixing member made of shape memory alloy for positioning a pair of right and left cores as fitting members. CONSTITUTION:In the case of abutting a pair of right and left cores 1a, 1b through a gap 2 and positioning and fixing them, the restoration force of the shape memory alloy made core fixing member 5 fitted to the pair of cores to a stored shape is utilized.

When the monitoring beams 9 having cross sectional area of several mm<2> are applied to such a sample, the reflection beams 10 are mostly reflected at the barrel longitudinal face. And utilizing the change of reflected light intensity of the beams 9 and 9', the etching finish time of the copper foil 22 is found. Hereby, excessive etching is reduced, and side etching is prevented, and further dispersion of pattern dimensions is reduced.
