Title: Lateral-disposition type semiconductor stack
Inventor: IIDA TAKEHISA
IPC: H01L23/473
Filed: 1982-02-15
Abstract: PURPOSE:To remove irregular load applied to a semiconductor element due to its own weight in a lateral-disposition type stack by forming means such as a gradient on the spring seat of a clamping mechanism or a spacer. CONSTITUTION:A spacer 15 is provided between the inside recess 11a of a spring retainer 11 which is opposed via a clamping spring 8 to a pressure plate 7 and the spring 8. The spacer 15 is formed in a circular disc shape and in a wedge shape which is thicker toward the lower side in section, the spring 8 is retained by the oblique seat 16, and secured by a pin 17. Thus, when the center of the spring 8 is set to the prescribed clamping load, irregular load which is low at the upper side and high at the lower side from the center is applied, and when the stack is laterally disposed, the bending load due to its own weight can be cancelled, thereby clamping the post surface of a flat semiconductor element in uniform load. Accordingly, even if the number of the elements is increased, no irregular load is applied, the stack having high reliability can be obtained, thereby reducing the number of the stacks.

Title: Method of supplying chemical for manufacture of semiconductor
Inventor: MITSUHORI SHIYUUICHI
IPC: B01J4/00
Filed: 1986-02-06
Abstract: PURPOSE:To enable the temperature of chemical liquid within a chemical liquid supply tank to be controlled precisely at a temperature level predetermined for a treating process, by previously passing the chemical liquid through a heat exchanger for regulating the temperature thereof to a temperature level predetermined for the treating process while feeding the chemical liquid so as to keep the amount of liquid within the supply tank within a certain range. CONSTITUTION:Chemical liquid in a storage tank 1 is fed, via a heat exchanger 3, to a chemical liquid supply tank 4 having a temperature regulator and an automatic liquid-level controller 6. The chemical liquid whose temperature has been regulated to a predetermined value in the supply tank 4 is further fed to a chemical liquid treating process 5. The feeding of the chemical liquid to the supply tank is performed such that a liquid-feeding pump stops the feeding if the liquid-level controller 6 detects a higher liquid level and it feeds the chemical liquid if the controller detects a lower level. Accordingly, a little variance in temperature of the chemical liquid fed through the heat exchanged, if any, may be absorbed in the supply tank. Further, since the variance in amount of liquid within the supply tank is also within a certain range, the temperature of the chemical liquid can be regulated precisely within the supply tank.

Abstract: PROBLEM TO BE SOLVED: To decrease bright lines and unequal luminance without lowering the incident efficiency of illumination light by adhering a light shielding means to the edges of an incident surface parallel with an exit surface to shield the light at these edge. SOLUTION: A light scattering light guide plate 11 is formed by adhering ink as the light shielding means to the upper and lower edges E of the incident surface 12 parallel with the exit surface so that bright lines are effectively averted by such ink. The edges E are formed a curved surface of about 0.05 in the radius R of curvature when macroscopically viewed and the ink is adhered in the form of ink layers 30 on such curved surfaces. The treatment to adhere the ink is executed by applying the ink on a planar member, then pressing the edges E to the ink in the state of inclining the light scattering light guide plate 11 at a prescribed angle. As a result, the ink is adhered to the edges E in the linear form of an extremely small line width. The illumination light entering from the edges E is shielded by the ink.  The white ink having high reflectivity to the illumination light is preferably used as this ink.
