摘要： An etching process for selectively etching exposed metal surfaces of a substrate and forming a conductive capping layer over the metal surfaces is described. In some embodiments, the etching process involves oxidation of the exposed metal to form a metal oxide that is subsequently removed from the surface of the substrate. The exposed metal may be oxidized by using solutions containing oxidizing agents such as peroxides or by using oxidizing gases such as those containing oxygen or ozone. The metal oxide produced is then removed using suitable metal oxide etching agents such as glycine. The oxidation and etching may occur in the same solution. In other embodiments, the exposed metal is directly etched without forming a metal oxide. Suitable direct metal etching agents include any number of acidic solutions. The process allows for controlled oxidation and/or etching with reduced pitting. After the metal regions are etched and recessed in the substrate surface, a conductive capping layer is formed using electroless deposition over the recessed exposed metal regions.

摘要： The present invention provides improved methods and devices for electroplating copper on a wafer. Some implementations of the present invention involve the pre-treatment of the wafer with a solution containing accelerator molecules. Preferably, the bath into which the wafer is subsequently placed for electroplating has a reduced concentration of accelerator molecules. The pre-treatment causes a reduction in roughness of the electroplated copper surface, particularly during the initial phases of copper growth.

摘要： A system and method for managing access to a plurality of carts. A plurality of users may be created in a database, each user having unique identifying information. Users may be grouped into user groups when having similar attributes. Each cart may have an entry in the database with associated attributes. Carts may be grouped into cart groups for carts having similar attributes. Users may be given access to cart either individually, through a user group that has access to the cart, by given access to an entire group of carts, or through a user group that has access to an entire group of carts. The various associations can be interwoven to provide groups and sub-groups for managing applications where multiple users must interact with multiple carts. The carts can store access logs which may be communicated in real time to a computing device or may be stored locally at the cart for later access by an administrator.

摘要： An anti-tip assembly for use with a shelving system movable along a track. The track includes a first flange overhanging a first longitudinally extending channel and a second flange overhanging a second longitudinally extending channel. The anti-tip assembly includes an open ended channel, and a first bracket having a first flange extending into a first open end of the open ended channel, and a second flange extending into the first channel of the track. The anti-tip assembly further includes a second bracket having a first flange extending into a second open end of the open ended channel, and a second flange extending into the second channel of the track. The first and second brackets are slidable inside the open ended channel and coupled together with a maximum spacing therebetween. A biasing member biases the first and second brackets outwardly away from one another within the maximum spacing.

摘要： Methods are provided for electrochemically depositing copper on a work piece. One method includes the step of depositing overlying the work piece a barrier layer having a surface and subjecting the barrier layer surface to a surface treatment adapted to facilitate deposition of copper on the barrier layer.
