ABSTRACT:
A method for high resolution maskless chemical and electrochemical machining is described. Preferential etching results from exposing those regions where machining is sought to an energy beam. Such exposures can increase the etching rate in the case of electrochemical machining by a factor of 10.sup.3 to 10.sup.4. Such enhancement is sufficient to make masking unnecessary.
