Applied Materials Announces Unique Capacitor Dielectric Solution for Advanced DRAM Manufacturing.Business Editors/High-tech Writers NOTE TO MEDIA: Photo is available in a Smart News Release(TM) on Business Wire's Home Page at www.businesswire.com SANTA CLARA, Calif.--(BUSINESS WIRE)--July 5, 2000 High Productivity Giga-Cap(TM) TanOx(TM) Centura(R)System Combines Ta2O5 CVD CVD Cardiovascular disease, see there with RTP (1) (Rapid Transport Protocol) The protocol used in IBM's High Performance Routing (HPR) system. (2) (Realtime Transport Protocol) An IP protocol that supports real time transmission of voice and video. To Enable Gigabit DRAM Chips Applied Materials, Inc. introduces the Giga-Cap(TM) TanOx(TM) Centura(R), a high-productivity system for the deposition of high k tantalum pentoxide (Ta2O5) dielectric films in advanced DRAMs. The system integrates the company's proven CVD (chemical vapor deposition) and RTP (rapid thermal processing Rapid Thermal Processing (or RTP) refers to a semiconductor manufacturing process which heats silicon wafers to high temperatures (up to 1200 C or greater) on a timescale of several seconds or less. ) technologies to provide customers with a production-worthy process to enable denser, more powerful memory chips. "Our new Giga-Cap TanOx Centura addresses many of the process integration and fab efficiency challenges involved in the formation of high k dielectric capacitors for 0.15 micron and below DRAM devices," said Dr. Dan Carl, vice president and general manager of the STI STI systolic time intervals. , Capacitor and PMD Division at Applied Materials. "While conventional Ta2O5 processing typically consists of a deposition system with a separate furnace for annealing annealing (ənēl`ĭng), process in which glass, metals, and other materials are treated to render them less brittle and more workable. , the Giga-Cap TanOx Centura's integrated deposition and anneal To take the brittleness out of metal, plastic or certain carbon composites. Performed in the preparation of new products or in their restoration, annealing is accomplished via a heat treating process. process combines these functions on a single system. It offers a 2x increase in productivity over conventional approaches, with a much smaller footprint and excellent device reliability down to at least 0.13 micron." The SIA Sia (sī`ə) or Siaha (sī`əhə), in the Bible, family returned from the Exile. SIA - Serial Interface Adaptor (Semiconductor Industry Association) Roadmap defines the need for high k dielectric materials such as Ta2O5 to replace currently-used silicon oxides and nitrides in order to continue reducing memory cell size and achieve higher chip densities required for new high performance devices. Ta2O5 allows chipmakers to reduce capacitor dimensions by enabling the storage of the required charge in a smaller structure. The Giga-Cap TanOx Centura system's Ta2O5 deposition/anneal process enables precise control of capacitance and leakage current, meeting the electrical and thermal budget requirements for DRAM (and embedded DRAM) devices with 0.15um geometries and below. Thin TanOx films (80 angstroms) deposited at low temperature (> 450 degrees C) provide smooth surface morphology and conformal step coverage for advanced capacitor structures, and are extendible for several DRAM generations. After the TanOx deposition, the system's integrated RTP anneal chamber performs a remote plasma oxidation and crystallization anneal which enhances dielectric film k value and reduces electrical current leakage. To further enhance electrical characteristics of the capacitor, a multiple deposition and anneal sequence can be performed without breaking vacuum. This efficient approach enables extension of TanOx to at least 0.13um device applications with high productivity. The Giga-Cap TanOx Centura System is the latest integrated process solution from Applied Materials. The company has also developed integrated processes for fabricating shallow trench isolation Shallow trench isolation (STI) is an integrated circuit feature which prevents electrical current leakage between adjacent semiconductor device components. STI is generally used on CMOS process technology nodes of 250 nanometers and smaller. (STI) structures, ultra-shallow junctions (USJ) and copper interconnects. These solutions offer customers the distinct advantage of processes that have been designed, tested and proven to work together in an optimized production flow.
