Embodiments of the present invention generally relate to sputtering of materials. In particular, the invention relates to sputtering voltage used during physical vapor deposition of large area substrates to prevent arcing. One embodiment of the invention describes an apparatus for sputtering materials on rectangular substrates at a voltage less than 400 volts, that comprises a sputtering target; wherein the target is biased at a voltage less than 400 volts during sputtering materials on the rectangular substrates, a grounded shield surrounding the sputtering target, wherein the shortest distance between the grounded shield and the sputtering target is less than the plasma dark space thickness, a magnetron in the back of the sputtering target, where in the edge of the magnetron does not overlap the grounded shield, and an antenna structure placed between the sputtering target and the substrate, wherein the antenna structure is grounded during sputtering.

A rectangular magnetron placed at the back of a rectangular sputtering target for coating a rectangular panel and having magnets of opposed polarities arranged to form a gap therebetween corresponding to a plasma track adjacent the target which extends in a closed serpentine or spiral loop. The spiral may have a large number of wraps and the closed loop may be folded before wrapping. The magnetron has a size only somewhat less than that of the target and is scanned in the two perpendicular directions of the target with a scan length of, for example, about 100 mm for a 2 m target corresponding to at least the separation of the gap between parallel portions of the loop. A central ferromagnetic shim beneath some magnets in the loop may compensate for vertical droop. The magnetron may be scanned in two alternating double-Z patterns rotated 90 between them.

The present invention generally provides a sputtering apparatus and method in which a sputtering target has a plurality of target sections bonded to a common backing plate. Each segment can be bonded to the common backing plate using a different bonding material. One target segment can be bonded to the backing plate using electrically conductive bonding material while another section is bonded to the backing plate using electrically insulating bonding material. Additionally, each different target section can be separately biased.

A power supply for a rechargeable battery in a portable computer system is disclosed which adjusts the level of charging current depending upon the current drawn by the portable computer system. The power supply includes an AC adapter which supplies input current for operating the computer system and for charging the battery. Sensors are connected to the AC adapter, the battery, and an output of the power supply to detect the level of input current from the AC adapter, the level of charging current supplied to the battery, and the output voltage level of the power supply. A controller is connected to each of the sensors and monitors the input current level, the charging current level, and the output voltage level. The controller generates a control signal which indicates whether any one of the levels has exceeded a respective predetermined maximum value. A charging current control circuit is connected to the controller and to the battery and controls current flow between the AC adapter and the battery based upon the control signal generated by the controller.

Films are modified to include deuterium in an inductive high density plasma chamber. Chamber hardware designs enable tunability of the deuterium concentration uniformity in the film across a substrate. Manufacturing of solid state electronic devices include integrated process flows to modify a film that is substantially free of hydrogen and deuterium to include deuterium.

Implementations described herein generally relate to a method for forming a metal layer and to a method for forming an oxide layer on the metal layer. In one implementation, the metal layer is formed on a seed layer, and the seed layer helps the metal in the metal layer nucleate with small grain size without affecting the conductivity of the metal layer. The metal layer may be formed using plasma enhanced chemical vapor deposition (PECVD) and nitrogen gas may be flowed into the processing chamber along with the precursor gases. In another implementation, a barrier layer is formed on the metal layer in order to prevent the metal layer from being oxidized during subsequent oxide layer deposition process. In another implementation, the metal layer is treated prior to the deposition of the oxide layer in order to prevent the metal layer from being oxidized.
