Abstract: A showerhead is provided. The showerhead includes a body and a plurality of first dispersion pins. The body has one side having a plurality of injection holes penetrated therethrough and the other side facing the one side. The plurality of first dispersion pins protruding from the plurality of spray holes of the one side to the other side such that end portions thereof support the other side. The first dispersion holes have first gas inlet holes on one side and first passages connected to the first gas inlet holes therein. Gas introduced between the one side and the other side is immediately discharged to the outside of the body through the plurality of spray holes by passing the first gas inlet holes and the first passages.

Abstract: A showerhead for film-depositing vacuum equipment having an effect shortening the length of injection tubes for a reactive gas is presented. The injection tubes extend from the bottom of a reactive gas showerhead module, and two different kinds of reactive gases are mixed with an injection support gas within a reactive showerhead module so as to inject the mixed gas. The showerhead for film-depositing vacuum equipment includes the reactive gas showerhead module above a cooling jacket and a purge gas showerhead module above the reactive gas showerhead module. The injection tubes of the reactive gas showerhead module pass through the cooling jacket disposed below the reactive gas showerhead module, and the injection tubes of the purge gas showerhead module pass through the reactive gas showerhead module disposed below the purge gas showerhead module, thereby enabling the purge gas to flow into a purge gas redistribution space defined above the cooling jacket.

Abstract: Disclosed is a piezoelectric ink jet printer head in which a chamber and an ink storage are integrally formed. A process for manufacturing the ink jet printer head is also disclosed.
