Patent ID: 8372687

Claim:
A method for forming multiple layers in a single process chamber comprising: placing a substrate in a first holder in the single process chamber having a plurality of processing sources, the first holder includes a first plurality of contact fingers; forming a conductive layer on the substrate in the process chamber, wherein the first plurality of contact fingers contacting the substrate in locations other than a plurality of bottom layer contact locations and wherein forming the conductive layer on the substrate includes forming the conductive layer in the plurality of bottom layer contact locations; and forming a copper indium gallium selenium (CIGS) layer including iteratively forming a plurality of thin CIGS layers, each one of the thin CIGS layers has a thickness of between 100 and 400 Angstroms, wherein forming each one of the thin CIGS layers including: forming a thin copper indium gallium (CIG) layer on the substrate including passing the substrate over at least one CIG source in the single processing chamber, the formed, thin CIG layer having a thickness of between 50 Angstroms and 200 Angstroms; forming a thin selenium layer on the formed, thin CIG layer including passing the substrate over at least one selenium evaporator source in the single processing chamber, the formed, thin selenium layer having a thickness of between 50 Angstroms and 200 Angstroms; and heating the substrate, the formed, thin CIG layer and the formed, thin selenium layer including passing the substrate over at least one heat source in the single processing chamber, wherein the substrate passes over the at least one CIG source, the at least one selenium evaporator source and the at least one heat source at a rate of between 1 times per minute and 100 times per minute.
