    摘要: Photovoltaic devices and methods for preparing a p-type semiconductor layer for the photovoltaic devices generally include electroplating a layer of gallium or a gallium alloy onto a conductive layer by contacting the conductive layer with a plating bath free of complexing agents including a gallium salt, methane sulfonic acid or sodium sulfate and an organic additive comprising at least one nitrogen atom and/or at least one sulfur atom, and a solvent; adjusting a pH of the solution to be less than 2.6 or greater than 12.6. The photovoltaic device includes an impurity in the p-type semiconductor layer selected from the group consisting of arsenic, antimony, bismuth, and mixtures thereof. Various photovoltaic precursor layers for forming CIS, CGS and CIGS p-type semiconductor structures can be formed by electroplating the gallium or gallium alloys in this manner. Also disclosed are processes for forming a thermal interface of gallium or a gallium alloy with the electroplating process.

    摘要: The present invention is related to a method for forming vertical conductive structures by electroplating. Specifically, a template structure is first formed, which includes a substrate, a discrete metal contact pad located on the substrate surface, an inter-level dielectric (ILD) layer over both the discrete metal contact pad and the substrate, and a metal via structure extending through the ILD layer onto the discrete metal contact pad. Next, a vertical via is formed in the template structure, which extends through the ILD layer onto the discrete metal contact pad. A vertical conductive structure is then formed in the vertical via by electroplating, which is conducted by applying an electroplating current to the discrete metal contact pad through the metal via structure. Preferably, the template structure comprises multiple discrete metal contact pads, multiple metal via structures, and multiple vertical vias for formation of multiple vertical conductive structures.

    摘要: A chalcogen-resistant material including at least one of a carbon nanotube layer and a high work function material layer is deposited on a transition metal layer on a substrate. A semiconductor chalcogenide/kesterite material layer is deposited over the chalcogen-resistant material. The carbon nanotubes, if present, can reduce contact resistance by providing direct electrically conductive paths from the transition metal layer through the chalcogen-resistant material and to the semiconductor chalcogenide material. The high work function material layer, if present, can reduce contact resistance by reducing chalcogenization of the transition metal in the transition metal layer. Reduction of the contact resistance can enhance efficiency of a solar cell including the chalcogenide semiconductor material.

    摘要: A Vertical Field Effect Transistor (VFET) formed on a substrate, with a conductive bottom electrode formed thereon. A bottom dielectric spacer layer and a gate dielectric layer surrounded by a gate electrode are formed thereabove. Thereabove is an upper spacer layer. A pore extends therethrough between the electrodes. A columnar Vertical Semiconductor Nanowire (VSN) fills the pore and between the top and bottom electrodes. An FET channel is formed in a central region of the VSN between doped source and drain regions at opposite ends of the VSN. The gate dielectric structure, that is formed on an exterior surface of the VSN above the bottom dielectric spacer layer, separates the VSN from the gate electrode.
