Patent ID: 7862694

Claim:
A composite coating device for forming a coating on a magnetic head, comprising: a first processing chamber for performing an ion beam etching process in which an ion beam is irradiated on a surface of the magnetic head at a predetermined angle to clean the surface, a second processing chamber for performing a magnetron sputter deposition in which a shock absorbing coating is formed on the surface, a third processing chamber for performing one of an electron cyclotron resonance plasma chemical vapor epitaxy and a cathode arc discharge deposition in which a protection coating is formed on the shock absorbing coating, a preparation chamber communicating with the first to third processing chambers through opening and closing means for transferring the magnetic head, and an ion beam etching device attached to the first processing chamber and including an ion source for generating ions, a plasma generating area, an electrode disposed between the first processing chamber and the plasma generating area for leading ions to the first processing chamber and having a first grid with a positive potential and a second grid with a negative potential, and a communicating port having a potential same as that of the first grid and passing through the first and second grids for communicating the plasma generating area and the first processing chamber, said communicating port allowing electrons in the plasma generating area to pass freely to the first processing chamber therethrough.
