Exhibits
For semiconductor and LED manufacturing, SGL CARBON GmbH supplies specialty graphites and graphite-based solutions used along the semiconductor production route. Specialty-graphite components are used in crystal growing and in subsequent processes such as epitaxy and ion implantation, where very high temperatures, highly corrosive environments, high purity and precision place demanding requirements on process materials. The semiconductor offering extends from high-purity graphite consumables for crystal-growing hot zones, including heaters, crucible susceptors and insulation, to high-precision graphite components for wafer-processing equipment. For epitaxy and MOCVD, the portfolio includes silicon-carbide-coated graphite susceptors, linking high-purity graphite and SiC coating technology with wafer-processing applications in semiconductor, LED and solar production. Listed semiconductor-related application areas include Semiconductor Crystal Growth, Polysilicon Production, High Temperature Furnaces, Process Technology for Corrosive Applications, and Silicon and SiC Epitaxy. Materials and product families shown for these applications include CARBOGUARD®, DIABON®, POLYFLURON®, SICABON®, SIGRABOND Carbon Fiber-Reinforced Carbon, SIGRABOND® Chemical, SIGRAFINE® Extruded and Vibration Molded Graphite, SIGRAFINE® Isostatic Graphite, SIGRAFINE® SiC Coating, SIGRAFLEX® High-Purity Flexible Graphite Foil and Sheets, SIGRAFLEX® graphite gasket sheets, SIGRASIC® Carbon Fiber Reinforced Silicon Carbide, and SIGRATHERM® Rigid Felt and Soft Felt. SGL CARBON GmbH states that it continuously invests in products and production processes for parts that are critical to advanced semiconductor-chip manufacturing, using high-purity materials that meet tight dimensional specifications. In silicon epitaxy, wafers are carried on graphite susceptors, and the properties and quality of those susceptors affect the quality of the wafer's epitaxial layer. Its SiC-coated graphite susceptors are described as combining extremely high purity, homogeneous coating, service life, chemical resistance and thermal stability, while high-precision machining and close coating tolerances are used to maintain a uniform susceptor profile. The company also produces materials with electrical-resistance properties for inductively heated systems, and finished components are supplied with purity and dimensional-compliance certificates. SGL CARBON GmbH supplies susceptors and graphite components for current epitaxy reactors, including barrel susceptors for applied and LPE units, pancake susceptors for LPE, CSD and Gemini units, and single-wafer susceptors for applied and ASM units. Additional components include heaters, support crucibles, heat shields and insulating components for single-crystal-growing processes and materials, together with susceptors for silicon epitaxy and MOCVD reactors. Application-specific finishing is available through cleaning, mechanical processing or coating, and the susceptors are made of high-strength isostatic graphite developed for processes including epitaxy, crystal growing, ion implantation, plasma etching and LED-chip production. The SIGRAFINE Fine-Grain Graphite Product Finder is provided to help pre-select graphite grades for an application, while quality controls support full product traceability and continued material and product development with manufacturers and operators of epitaxy units. Technical information is listed for SIGRAFINE isostatic graphites for electronic applications and for grades R6140, R6300, R6303H, R6340, R6410, R6500, R6510, R6650, R6710, R6810, R6910 and V2114, as well as SIGRAFINE SiC Coating and handling instructions for coated parts. SGL CARBON GmbH also combines materials expertise and manufacturing know-how with partnerships with leading OEMs to develop application-specific susceptor designs, while continuing material and product development in collaboration with manufacturers and operators of epitaxy units.
