(Nasdaq:AMAT - news) today announced the grant of patents No. 6,287,990 and No. 6,303,523 by the U.S. Patent & Trademark Office covering advanced low k dielectric CVD (chemical vapor deposition) film technology used to increase the speed and performance of next-generation chips. To date, Applied Materials has been awarded more than 15 CVD low k-related patents that enhance its powerful patent portfolio in this strategic technology area. ``These new patents cover some of our most important intellectual property regarding low k dielectric films,'' said Dr. Farhad Moghadam, vice president and general manager of Applied Materials' Dielectric Systems and Modules Product Business Group. ``They protect our Black Diamond(TM) technology and demonstrate our leadership in providing customers with innovations to meet their next-generation chip design requirements.'' Issued in September and October 2001, both patents center on Applied Materials' Black Diamond technology, a family of organosilicate glass-based low k dielectric products. Introduced in November 1998, Black Diamond enables chipmakers to cost-effectively integrate a low k dielectric (k less than 3.0) using conventional CVD equipment and silicon-based materials. Black Diamond can be used with Applied Materials' BLOk(TM) dielectric CVD barrier and etch stop film to further lower the overall k value of chip interconnect structures. Black Diamond technology has achieved growing global acceptance, with 17 chipmakers working with it in development. The product line's first film, targeting 0.13-0.10 micron devices, is the industry's leading production-worthy low k dielectric material and has demonstrated the unique capability to be used on every level for 8-level copper interconnects. Customers are expected to ship chips that integrate Black Diamond in 2002. Applied Materials (Nasdaq:AMAT - news), the largest supplier of products and services to the global semiconductor industry, is one of the world's leading information infrastructure providers.
