20110117680 | INLINE DETECTION OF SUBSTRATE POSITIONING DURING PROCESSING - Embodiments of the present invention generally provide a method for detecting the position of a substrate within a processing chamber. Embodiments of the present invention are particularly useful for the detection of a mis-positioned solar cell substrate during photoabsorber layer deposition processes within a solar cell production line. Reflected power is measured during processing of a substrate and communicated to a system controller. The system controller compares the measured reflected power with an established range of reflected power. If the measured reflected power is substantially out of range, the system controller signals for the chamber to be taken offline for inspection, maintenance, and/or repair. The system controller may further divert the flow of substrates within the production line around the offline chamber without shutting down the entire solar cell production line. | 05-19-2011 |
20130260555 | METHOD OF ENABLING SEAMLESS COBALT GAP-FILL - Methods for depositing a contact metal layer in contact structures of a semiconductor device are provided. In one embodiment, a method for depositing a contact metal layer for forming a contact structure in a semiconductor device is provided. The method comprises performing a cyclic metal deposition process to deposit a contact metal layer on a substrate and annealing the contact metal layer disposed on the substrate. The cyclic metal deposition process comprises exposing the substrate to a deposition precursor gas mixture to deposit a portion of the contact metal layer on the substrate, exposing the portion of the contact metal layer to a plasma treatment process, and repeating the exposing the substrate to a deposition precursor gas mixture and exposing the portion of the contact metal layer to a plasma treatment process until a predetermined thickness of the contact metal layer is achieved. | 10-03-2013 |
