摘要:
A method for forming an ink jet nozzle plate includes providing a structure having a top substrate layer, a bottom substrate layer, and a buried layer disposed between the top substrate layer and the bottom substrate layer; providing a composite mask over the top substrate layer having a cavity mask which provides openings and a bore mask having openings which are entirely within the openings of the cavity mask and extend to the top substrate layer; anisotopically etching through the bore mask openings through top substrate layer and the buried layer into a portion of the bottom substrate layer; removing the bore mask and etching the top and bottom substrate layers without substantially affecting the buried layer to extend the openings in the top substrate layer and the bottom substrate layer; removing the cavity mask and attaching the top substrate layer to a base provided with ink delivery channels with correspond to the openings in the buried layer; and removing the bottom substrate layer.
