Abstract
The method and apparatus manufacture a liquid drop ejecting head. The method and apparatus blast particles on a substrate having on an upper layer a patterned mask layer made of an organic material and on a lower layer a driver circuit for ejecting a liquid drop to thereby perform an etching process on parts of the substrate exposed from the mask layer. The etching process is performed in an ionic atmosphere ionized with a polarity opposite to a charged polarity generated in the substrate when the substrate is subjected to etching.
