    摘要: A system for processing a substrate is provided including a first planar motor, a substrate carrier, a first processing chamber, and a first lift. The first planar motor includes a first arrangement of coils disposed along a first horizontal direction, a top surface parallel to the first horizontal direction, a first side, a second side. The substrate carrier has a substrate supporting surface parallel to the first horizontal direction. The first processing chamber has an opening to receive a substrate disposed on the substrate carrier. The first lift includes a second planar motor having a second arrangement of coils disposed along the first horizontal direction. A top surface top surface of the second planar motor is parallel to the first horizontal direction. The first lift is configured to move the top surface of the second planar motor between a first vertical location and a second vertical location.

    摘要: Embodiments of the present invention generally provide improved processes and apparatus for removing passivation layers from a surface of photovoltaic cells and improving contact resistance in rear point contact photovoltaic cells. In one embodiment, a method of processing a solar cell substrate includes providing a substrate having a passivation layer deposited on a first surface of the substrate. The passivation layer is a layer stack comprising an aluminum oxide and a silicon nitride. The method also includes exposing the first surface of the substrate to an etchant, and heating the etchant to dissolve the aluminum oxide of the passivation layer on the first surface. The method may further include forming a metal containing layer on a second surface of the substrate that is opposite to the first surface.

    摘要: The present disclosure generally relates to methods and apparatus for facilitating electrical feedthrough in plasma processing chambers. The apparatus includes an electrically insulating housing positioned on a backside of the substrate support to contain a secondary plasma therein. The secondary plasma facilitates an electrical connection between the substrate support and electrical power or ground located outside the processing chamber. The methods include utilizing a secondary plasma to electrically couple substrate support to and electrical power or ground located outside the processing chamber.
