Granted: 2002-05-11
Abstract: In accordance with the present invention, a mask correction rule is prepared by taking the correlation of the dimensional variation in the wafer and the amount of correction so that identical devices may be manufactured by a plurality of different manufacturing apparatus. Finished wafers are electrically measured for the dimensional variation of the pattern and the dependency on the distance to the nearest neighbor with an ACLV after the entire process to determine the dimensional variation per edge of the pattern on the wafer (steps S11a, S12a). A correction factor is determined from the correlation of the designed dimensions and the actual dimensions of the finished products, and the dependency on the distance to the nearest neighbor of the correction factor is obtained (steps S11b, S12b). Then, the dependencies on the distance to the nearest neighbor are made to agree with each other by dividing dimensional variation per edge by the correction factor (step S13). The obtained result is sorted by the minimum grid width of the mask writing system to determine the x-coordinate of each of the points on the grid of the mask writing system (step S14). The correction region for 1 grid, the correction region for 2 grids, and so on are determined in accordance with the x-coordinate obtained (step S15).

After the called procedure module reads the data stored in the main mapping file, it operates according to the read data. The called procedure module also opens a called mapping file for storing the data intended to be returned to the main procedure module. The called procedure module returns the control right back to the main procedure module after completing the called situation, then the main procedure module reads the returned data from the called mapping file for updating.

Title: Bias circuit and method for decreasing semiconductor memory burn-in test time and preventing junction breakdown
Inventor: TZENG JIUN-CHIN
IPC: G11C7/00
Filed: 1999-01-28
Granted: 2001-06-16
Abstract: The present invention provides a bias circuit and a method used for semiconductor memory to decrease the burn-in test time and decrease the number of times for experiencing the burn-in test time. When the first voltage value is added from the external portion to the semiconductor memory apparatus to enter into the burn-in step, the back bias of substrate will be decreased. When the memory apparatus leaves the burn-in condition, the back bias quantity of substrate will return to the original operation level as the second voltage value is added from the external portion. The decreased back bias of substrate allows higher external voltage to add stress to semiconductor memory and will not force to punch through this semiconductor memory such that it is capable of having shorter test time. When entering into the burn-in test, higher external voltage than that added for the time of leaving burn-in condition is added. Providing stronger external bias for the burn-in test is helpful to decrease the number of times for experiencing time.

Title: Semiconductor package with molding compound flange and fabrication method thereof
Inventor: HUANG JIAN-PING
IPC: H01L23/28
Filed: 2000-03-09
Granted: 2003-03-21
Abstract: A semiconductor package with molding compound flange is provided. A substrate for carrying a chip is electrically connected with the chip and a molding compound made from curing a molding resin encapsulates the chip and a portion of the surface of the substrate. A mold with a top mold and a bottom mold is used to mold the molding compound, in which the top mold has a cavity formed from a recess formed by an extending the opening periphery. After the molding compound is molded, its connection region to the substrate will form an outward extending flange. Because the recess will form a slit after the top mold and the bottom mold close, the resin mold flow enters the recess and absorbs the mold thermal energy, during a molding process, leading to an increased viscosity. The increase in viscosity of resin mold flow results in reduced flow rate and thus the resin mold flow will not flash outside of region where the substrate is covered by the molding compound. Therefore, there is no concern of flash in the molding process, molding pressure can be reduced and micro-cracks on the substrate due to excessive molding pressure can be reduced.
