Patent JP-H11238824-A (JP)
Title: Semiconductor package
Inventor: NARISAWA HIROSHI
IPC: H01L23/08
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To reduce a warpage and a twist in a semiconductor package by a method wherein a glass woven fabric with a specific ratio of the number of interweaving of warps to the number of interweaving of wefts is used as the base material for the package and a laminated board using a hardened material constituting of a thermosetting resin as its matrix is used as the insulating layer material for the package. SOLUTION: The number of interweaving is shown by the number of threads which are interweaven in per 25 mm. When the ratio (the number of warps to the number of wefts) of the number of interweaving is less than 1.0, the expansion and contraction of the threads to the direction of the warp are increased relatively to each other when a temperature is changed and when the ratio exceeds 1.1, the expansion and contraction of the threads to the direction of the weft are increased relatively to each other when a temperature is similarly changed. As a result, by using a glass woven fabric with the ratio of the numbers of interweaving of 1.0 to 1.1, a warpage and a twist in a semiconductor package can be lessened.  Moreover, a warpage and a twist in a semiconductor package of a structure, wherein such the glass woven fabric is used as a base material for the package and a laminated board using a hardened material comprising a thermosetting resin, such as a multifunctinal epoxy resin, as its matrix is used as an insulating layer material for the package, can be made smaller.

Filed: 1980-03-26
Abstract: PURPOSE:To make an emitter to be automatically subjected to strong flushing by automatically detecting the deterioration of the emitter, and making a timing signal for flushing to be produced. CONSTITUTION:A switch circuit 21 is usually opened, and any electric power is not supplied from a heat power-source 22 to an emitter 1. Signals proportional to probe currents are supplied to a divider 11 through amplifiers 10 and 15, while a signal representing the current of full discharged electrons is supplied to the divider 11 from the emitter 1. The output of the dividing circuit, together with the output of a function generator 18, is applied to a dividing circuit 16 as an input. When the output of the dividing circuit 16, which is supplied to a comparator 19, becomes below a standard voltage supplied from a reference power source 20, the comparator 19 sends a signal which works for subjecting the emitter 1 deteriorated to strong flushing. As a result, the switch circuit 21 is closed, and the emitter undergoes strong flushing by the heat current supplied from the heat power source 22.
