Process error prevention method in semiconductor fabricating equipment

A method for preventing process errors in a semiconductor fabricating process allows only a few authorized engineers to release interlocks of semiconductor fabricating equipment when a count of interlock occurrences exceeds a predetermined number within a predetermined period of time. By allowing a semiconductor fabricating equipment operator only limited ability to reset equipment interlocks, repeated interlock conditions caused by test specification failures may be over-ridden only a predetermined number of times before the semiconductor fabricating equipment is disabled completely. The disabled semiconductor fabricating equipment may only be re-enabled using an authorization code, which is only made available to selected personnel, thereby ensuring that necessary repairs and corrections have been implemented on the semiconductor fabricating equipment.
