摘要:
A plasma source is designed with a starting rod to reduce target vapor shielding. A curve ion duct has reverse thorns on its inner wall to filter macroparticles in plasma. The curve ion duct has duct segments and each duct segment has an individual electricity. The present invention increases ion amount, acquires a film through high energy ions, and obtains enhanced film adhesion and film quality.
摘要:
An apparatus provides large area atmospheric pressure plasma enhanced chemical vapor deposition without contaminations in its electrode assembly and deposited films. The apparatus consists of a large area vertical planar nitrogen plasma activation electrode assembly and its high voltage power supply, a large area vertical planar nitrogen plasma deposition electrode assembly and its high voltage power supply, a long-line uniform precursor jet apparatus, a roll-to-roll apparatus for substrate movement, and a sub-atmospheric pressure deposition chamber and its pumping apparatus. Not only can the deposited film contaminations in the electrode assembly interior and the debris of the deposited films from exterior of the electrode assembly and the air aerosols in the deposition chamber be completely prevented, but a large area roll-to-roll uniform deposition can also be achieved to meet a roll-to-roll continuous production, so as to achieve improved film quality, increased production throughput and reduced manufacturing cost.
摘要:
There is a disclosed apparatus for coating diamond on work pieces via hot filament chemical vapor deposition. The apparatus includes a chamber, a pump for pumping air from the chamber, a pressure controller for con trolling the pressure in the chamber, a grid disposed in the chamber, a grid-bias power supply for providing a positive bias to the grid, a holder for carrying the work pieces, a holder-bias power supply for providing a negative bias to the holder, filaments provided between the grid and the carrier, a filament power supply for energizing the filaments to heat up, a programmable temperature controller for controlling the temperature in the chamber and a pipe for transferring reaction gas into the chamber.
