The bulk layer may contain copper, but generally contains tungsten deposited by a chemical vapor deposition (CVD) process. In some examples, the bulk layer may be used to fill apertures within the substrate.

  • Patent number: 7752215
    Abstract: A method, system and article of manufacture for protecting sensitive data in databases and, more particularly, for managing access to sensitive data in a database. One embodiment comprises receiving a query against the data in the database comprising at least (i) a result field specification, and (ii) a sorting instruction. The method further comprises retrieving a result set from the database, and filtering the retrieved result set on the basis of predefined filtering rules to remove selected data from a selected result field of at least one data record included with the retrieved result set. The filtered result set is sorted according to the sorting instruction to produce the sorted result set, whereby the sorting is done independently of the removed selected data so that the sorted result set places the at least one data record at a position which is non-indicative of a value of the removed selected data.

  • Patent number: 7736928
    Abstract: Embodiments of the invention contemplate the formation of a low cost solar cell using a novel electroplating apparatus and method to form a metal contact structure having metal lines formed using an electrochemical plating process. The apparatus and methods described herein remove the need to perform the often costly processing steps of performing a mask preparation and formation steps, such as screen printing, lithographic steps and inkjet printing steps, to form a contact structure. The resistance of interconnects formed in a solar cell device greatly affects the efficiency of the solar cell. It is thus desirable to form a solar cell device that has a low resistance connection that is reliable and cost effective. Therefore, one or more embodiments of the invention described herein are adapted to form a low cost and reliable interconnecting layer using an electrochemical plating process containing a common metal, such as copper.
