IPC: H01L21/78
Filed: 1989-09-13
Abstract: PURPOSE:To form a thin water in a uniform thickness by a method wherein a protective resin layer is formed, so as to be thicker than a protrusion, and hardened on the surface of a water on which a semiconductor chip having the protrusion is formed, the back is ground, the protective resin layer is stripped off after that and the water is separated into individual chips. CONSTITUTION:A resist liquid whose viscosity is high is dripped onto the surface of a water 10; it is spin-coated so as to be thicker than a bump electrode 11. After that, the resist liquid is hardened to form a protective resin layer 12. Then, the wafer is placed on a pedestal 13 in such a way that the layer 12 is faced downward; in this state, the rear is ground to make the water 10 thin. After that, this assembly is immersed in a resist-dissolving liquid; the layer 12 is stripped off; the assembly is diced and separated into individual semiconductor chips. Thereby, a thin water can be formed in a uniform thickness; a breakage and a crack are reduced.

Abstract: PROBLEM TO BE SOLVED: To attain generation of optical pulses of 1-10 ps, waveform shaping, waveform measurement, waveform recording and correlative processing by providing a mirror for reflecting incidence of light focused by a second means for focusing the optical output of a waveguide array. SOLUTION: After entering a quartz wave guide 1, an input optical signal u (t) is diverged into an array 3 of N-number of wave guides by a star coupler 2. The wave guide array 3 is so set as to have optical path length difference ΔL between an incident face S1 and an outgoing face S2 . Frequency resolution is proportional to Nm at the time of using m-order diffracted light, where N is the number of wave guides of the wave guide array 3. Large resolution can therefore be obtained by enlarging (m). A reflecting space filter 5 is installed at a focal plane S3 of such a wave guide array 3 of high resolution, and when the space frequency pattern of the space filter 5 is made H (v), an optical pattern of U (v) H (v) is reflected and goes back through the wave guide array 3 and star coupler 2 so as to be outputted from the quartz wave guide 1.

Abstract: PROBLEM TO BE SOLVED: To make the drain condensed on a surface easily dropped, by installing an evaporator at an area where the direction of an air duct is changed from the horizontal direction to the upper direction, in such a manner that it is inclined so that an edge part at an inlet port side is higher than the inlet port, and the other edge part is lower than the same. SOLUTION: An evaporator 4 is installed at an area where a direction of an air duct is changed from a horizontal direction to an upper direction, and is inclined so that an edge part at an inlet port 25 side is located higher than the inlet port 25, and the other edge is located lower than the inlet port 25. This inclination angle is more than 20 deg. to the horizontal direction, preferably more than 30 deg.. That is, when the inclination angle is less than 30 deg., the air pressure loss is rapidly increased, and the heat exchanging quantity is lowered. To smoothly exhaust the drain, the inclination angle is preferably more than 25 deg., or to keep the lowering of the heat exchanging performance within 5%, the inclination angle is preferably more than 30 deg.. By inclining the evaporator, the height of the casing can be reduced.
