摘要： A temperature controlled showerhead assembly for chemical vapor deposition (CVD) chambers enhances heat dissipation to provide accurate temperature control of the showerhead face plate and maintain temperatures substantially lower than surrounding components. Heat dissipates by conduction through a showerhead stem and removed by the heat exchanger mounted outside of the vacuum environment. Heat is supplied by a heating element inserted into the steam of the showerhead. Temperature is controlled using feedback supplied by a temperature sensor installed in the stem and in thermal contact with the face plate.

摘要： Apparatus and methods for electroplating metal onto substrates are disclosed. The electroplating apparatus comprise an electroplating cell and at least one oxidization device. The electroplating cell comprises a cathode chamber and an anode chamber separated by a porous barrier that allows metal cations to pass through but prevents organic particles from crossing. The oxidation device (ODD) is configured to oxidize cations of the metal to be electroplated onto the substrate, which cations are present in the anolyte during electroplating. In some embodiments, the ODD is implemented as a carbon anode that removes Cu(I) from the anolyte electrochemically. In other embodiments, the ODD is implemented as an oxygenation device (OGD) or an impressed current cathodic protection anode (ICCP anode), both of which increase oxygen concentration in anolyte solutions. Methods for efficient electroplating are also disclosed.

摘要： Methods and apparatus are provided for planar metal plating on a workpiece having a surface with recessed regions and exposed surface regions; comprising the steps of: causing a plating accelerator to become attached to said surface including the recessed and exposed surface regions; selectively removing the plating accelerator from the exposed surface regions without performing substantial metal plating on the surface; and after removal of plating accelerator is at least partially complete, plating metal onto the surface, whereby the plating accelerator remaining attached to the surface increases the rate of metal plating in the recessed regions relative to the rate of metal plating in the exposed surface regions.
