Patent TW-I250568-B (TW)
Title: Method of producing a semiconductor device
Inventor: ICHIKAWA SEIJI
IPC: H05K3/00
Filed: 2001-05-30
Granted: 2006-03-01
Abstract: A method of producing a semiconductor device of the present invention is applicable to a multilayer wafer for leadless chip carrier packages and breaks it on a package basis. The method begins with a step of forming a generally V-shaped groove in one major surfaces of the wafer in the direction of thickness of the wafer. A weak, cleaving portion is formed in the other major surface of the wafer in alignment with the groove. A cleaving force is exerted on the wafer to thereby form a break in the cleaving portion, so that the wafer is caused to break from the groove toward the cleaving portion in the direction of thickness of the wafer. The cleaving portion may be replaced with a strong, non-cleaving portion, in which case the break is formed in the interface between the non-cleaving portion and the wafer due to a difference in cleaving force.

Granted: 2004-02-21
Abstract: A semiconductor package test board for conveniently testing a fine ball pitch ball grid array package is provided. The provided semiconductor package test board includes a socket contact unit formed of a plurality of layers, to which a socket having the semiconductor package is connected, wherein the pitch between holes to which pins of the socket are connected increases from the upper surface to the lower surface in the socket contact unit. The holes in the socket contact unit are inclined toward the edges of the socket contact unit, and the angle of inclination of the holes increases from the center of the socket contact unit to the edges of the socket contact unit. Therefore, the holes are formed such that the ball pitch increases from the top layer to the bottom layer. As a result, the socket having the semiconductor package can be directly mounted on the test board without additionally mounting the sub test board (the socket board). In addition, the holes are formed perpendicular to each layer of the socket contact unit, to connect the holes to those on the layers above by using a conductor. As a result, problems such as deterioration of characteristics caused by contact error can be solved.
