Title: Manufacture of low-temperature burned multilayered ceramic substrate
Inventor: YAMAGUCHI KAZUHIRO
IPC: H05K3/46
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To suppress a change in a factor of shrinakge as much as possible by a method wherein a laminated material is so formed as to have standardized and prescribed longitudinal and lateral dimensions, the gross area of the laminated material to be burned is made a prescribed one and the material is cut in desired substrate dimensions. SOLUTION: A circuit forming region 4a inside a laminated material 13 corresponds finally to a low-temperature burned multilayer ceramic substrate and a circuit is formed only in the central part of green sheets 14a-14d. Although the size of the circuit forming region 4a is varied in a large degree with a scale of the circuit and construction of a circuit conductor pattern 2a, the longitudinal and lateral dimensions of the green sheets 14a-14d used herein are always prescribed ones and processes of lamination and primary burning are conducted with these dimensions unvaried. After the primary burning, an outer peripheral part is cut off with the part of the circuit forming region 4a left behind and thereby the lowtemperature burned multilayer ceramic substrate is obtained.  According to this method, the degree of integration of the factors of a change in a shrinkage percentage which are inherent in the green sheets can always be made a prescribed one and a difference in the shrinkage percentage due to burning can be made to hardly occur.
