Title: Semiconductor device
Inventor: KATO SUNAO
IPC: H01L23/50
Filed: 2000-02-03
Abstract: PROBLEM TO BE SOLVED: To prevent the peeling of externals leads from a substrate by preventing stresses from developing on the joining surfaces of the substrate with the external leads even when a semiconductor is subjected to thermal stresses after the device is mounted on the substrate by determining the joining intervals of the facing external leads of the semiconductor device to the substrate, based on the ratio between the coefficients of thermal expansion between the device and substrate. SOLUTION: Usually, the coefficient of thermal expansion of a substrate 2 is about four times as large as that of a semiconductor device, because the ratio between the coefficients of thermal expansion of the device and substrate 2 is about 1:4. Therefore, when the facing external leads 1 of the semiconductor device are formed in such a way that the joining internal (w) of the leads 1 to the substrate 2 may become 1/4 of the total width W of the semiconductor device and joined to the substrate 2 near the lower central part of the semiconductor device, the peeling of the leads 1 from the substrate 2 does not occur, because theoretically there are no stresses developed by thermal expansion.  In addition, when the leads 1 are joined to the substrate 2 in such a manner that the joining end sections of the leads 1 to the substrate 1 are alternately arranged along the lower center line of the device, the stresses applied to the leads 1 can be reduced, because only the stress which is developed by the thermal expansion of the semiconductor device is applied to the joining sections 3.
