Title: Semiconductor element accommodation package
Inventor: HASHIGUCHI EIICHI
IPC: H01L23/08
Filed: 1990-04-28
Abstract: PURPOSE:To normally and stably operate for a longer period a semiconductor element to be accommodated by forming an insulating substrate with mullite type sintered material and ensure perfect sealing by identifying a thermal expansion coefficient of a metal cover. CONSTITUTION:A thermal expansion coefficient of a cover 2 joined to the upper surface of an insulating substrate 1 consisting of mullite type sintered material is set to 3.5 to 5.0X10<-6>/ deg.C(20 to 400 deg.C). Thereby, the thermal expansion coefficients of the insulating substrate 1 and cover 2 can be approximated with each other. As a result, on the occasion of joining a cover 2 on the upper surface of the insulating substrate 1, a thermal stress resulting from difference of the thermal expansion coefficients is not almost generated between the insulating substrate 1 and the cover 2. Accordingly, the conver 2 can be joined very strongly to the insulating substrate 1 in order to realize perfect hermetical sealing of the vessel. Thereby, semiconductor integrated circuit accommodated therein can be normally and stably operated for a long period of time.

Abstract: PURPOSE:To permit the needle of a multi-degree-of-freedom actuator used for optical pick up, the manipulator hand of a robbot, etc., to be driven in the free directions. CONSTITUTION:Pressure control for driving a needle 12 is carried out by heating elements 13a-13s which use resistance heating method, etc., so as to generate bubbles in liquid 15 and controlling the pressure in the bubbles. For example, when the needle 12 is to be driven in the Z-axis positive direction, the heating elements 13i-13k are control-heated to suitably expand the bubbles of 14i-14k. Then, the heat quantity of the heating elements 13r-13s is controlled to be reduced and bubbles 14r-14s are suitably shrinked. Thus, rotation in the three- axis directions is allowed by controlling a baloon.
