Title: Correction of lacking defect in photomask and device thereof
Inventor: MIZUKOSHI KATSURO
IPC: G03F1/72
Filed: 1985-03-29
Abstract: PURPOSE:To make the transfer of any defect impossible in case it is exposed by a method wherein, when a lacking defect in a part of photomask provided on a glass substrate is to be corrected, glass etchant is dripped on the defective part to be irradiated with laser beams making the substrate on this part rugged. CONSTITUTION:When any lacking defect 4 is detected in a photomask 1 formed of a pattern 3 on the surface of a glass substrate 2, the defect can be corrected as follows, i.e. a lens 10 corresponding to the defect 4 is provided below the substrate 2 and then beams 11 transmitting the lens 10 are focussed on the surface of substrate 2 to drip glass etchant 6 until it reaches the ends of pattern 3 while filling the exposed surface of substrate 2 with the etchant 6. Next the intensity of laser beams 11 is controlled to form the peripheral surface of defect 4 into rugged recessions and then the needless etchant 6 is removed. Through these procedures, when a wafer is exposure-processed through the intermediary of the mask 1, any image of the defect 4 can not be formed on the wafer since incoming beams are changed into turbulent reflected beams 8 and turbulent refracted beams 9 around the peripheral parts of the recessions.
