Cleaning apparatus of semiconductor device

Abstract

A nozzle for spraying a cleaning solution, a body of the nozzle having its intake at one end, its sealed end portion at the other end, and a plurality of holes arranged linearly on its surface form inside of the body to outside of the body are disclosed. Also disclosed is a cleaning apparatus of a semiconductor device which includes a bath where wafers are cleaned and a cleaning solution spraying nozzle mounted at the bottom of the bath for spraying a cleaning solution through a plurality of holes formed on its surface, with the nozzle's one side being connected to a cleaning solution supply tube and the nozzle's other side being sealed. The hole's area through which the solution passes gradually decreases from one side of the nozzle through which the cleaning solution is induced, to the other side sealed so that the solution is sprayed with a uniform pressure.
