          Application No. 08/564,659                                                  


               the anode, the gas-introducing means, the first means, the             
          second means and the third means being disposed relative to the             
          target and the substrate to provide for the flow of the sputtered           
          atoms from the target to the substrate without any obstruction.             
               104.  An apparatus as set forth in claim 103, including,               
               there being in the substrate a groove defined by walls,                
               a shield disposed between the anode and the substrate without          
          obstructing the flow of sputtered atoms from the target to the              
          substrate and operative at a potential less than the positive               
          voltage on the anode to receive charged particles moving toward the         
          substrate,                                                                  
               there being a positive voltage on the anode with a magnitude,          
          and there being a voltage difference between the anode and the              
          target with a magnitude, to obtain a deposition on the substrate            
          of the material of the target to fill the groove and to provide a           
          deposition with a substantially smooth surface of the deposition on         
          the substrate at the positions of the groove and at the positions           
          removed from the groove.                                                    
               105.  An apparatus as set forth in claim 103, including,               
          there being in the substrate a groove defined by walls,                     
               the third means including magnetic means for providing a               
          substantially constant magnetic field for increasing the distance           
          of movement of the electrons toward the target to enhance the               
          ionization of the atoms of the inert gas in the cavity, the third           
          means including the magnetic means being operative to enhance the           
          ionization of the atoms of the inert gas in the cavity without              
          obstructing the flow of the sputtered atoms from the target to the          
          substrate,                                                                  
               the substrate being at a voltage lower than the positive               
          voltage on the anode,                                                       
               the anode having a magnitude, and the difference between the           
          voltages on the anode and the target having a magnitude, to obtain          
          a deposition of a substantially uniform thickness of the sputtered          

                                          15
