Filed: 1989-09-11
Abstract: PURPOSE:To control delay time until ringing is started for each warning device by providing a timer circuit to arbitrarily set the delay time from the start of warning ringing in a preceding step to the start of warning ringing in the next step corresponding to each warning. CONSTITUTION:Timer circuits 41-44 are provided to arbitrarily set from the start of warning ringing in the preceding step to the start of warning ringing in the next step corresponding to the respective warnings. When a signal for arbitrarily setting a warning device 70 in the preceding step is turned to an ON (driving) state, the timer circuit 41 starts the operation and after the lapse of set time only, a warning device 71 to be signal for driving a warning device 71 to be connected with the timer circuit 41 is set in the ON state.

Title: Method for detecting positional deviation
Inventor: HASEGAWA TAKAYASU
IPC: G01D5/38
Filed: 1994-09-30
Abstract: PURPOSE: To correct the linear and nonlinear errors of a detector so as to improve the measurement accuracy of the detector by measuring the relative positional deviation between each diffraction grating pair of a plurality of diffraction grading pairs for correction and correcting the relative positional deviation based on the relational approximation between the measured and actual positional deviations between each diffraction grating pair. CONSTITUTION: A table 5 on which a diffraction grating group 4 having a known relative positional deviation used for correction is formed is positioned at the same height as that of a wafer 3 to be measured and the positional deviations of the diffraction grating pairs are successively measured. When a graph indicating the relation between the actual (known) and measured positional deviations is plotted and expressed by a linear approximation, X/Pb=F(Xm/Pb) (where, Xm, X, Pb, and F respectively represent the measured and actual positional deviations, designed pitch value on a reticle, and constant) is obtained.  Therefore, when the constant F is found from the measured results and measured values are corrected by multiplying the measured results of a diffraction grating pair having an unknown relative positional deviation by the constant F, the nonlinear and linear errors of the electrical system of a detector can be corrected.
