Title: Method for determining center position of pattern from position detection signal
Inventor: KITAJIMA HIRONOBU
IPC: G01B11/00
Filed: 1989-04-07
Abstract: PURPOSE:To remove noises without averaging operation and to improve position determination accuracy by scanning a pattern for position detection optically, converting detected light into a position position detection signal photoelectrically, and converting the position detection signal into an area of the spatial frequency of a position by Fourier transformation. CONSTITUTION:The pattern for position detection is scanned optically, the detected light (reflected light, diffracted light, etc.) is converted photoelectrically into the position detection signal Ix having an axis of symmetry, and the position detection signal Ix is converted into the area of the spatial frequency omegaof the position (x) by Fourier transformation. Then the characteristic straight line of the phase thetaomega of the Fourier-transformed signal Iomega is found and the position of the pattern center is determined according to the gradient of the straight line in the spatial frequency area where the influence of noises is small. Therefore, the noises are removed without averaging operation and the accuracy of the pattern center position detection can be improved.

IPC: H01L21/02
Filed: 1992-04-10
Abstract: PURPOSE:To provide a resin forming device which not only enables resin to be surely controlled in discharge and prevented from leaking out from a mold but also protects a semiconductor wafer against damage caused by thermal stress so as to improve it in yield. CONSTITUTION:An discharge nozzle 17a is previously put in discharge operation before resin is discharged from the discharge nozzle 17a, made to previously stop a discharge operation before t,1ne discharge of resin is ended, and made to restart a discharge operation after the discharge of resin is ended, whereby voids are prevented from occurring in resin. As the fine tip of the discharge nozzle 17a is located at the periphery of resin formed on the circumferential part of a semiconductor wafer 1, resin hardly leaks out from a female mold holder 16g, so that a resin forming device of this design can be improved in operation rate and material efficiency. Furthermore, as a semiconductor wafer is stopped adjacent to the female mold 16a for a prescribed time, preheated, and set to the female mold 16a, the semiconductor wafer can be protected against thermal damage.
