AC 2000-P3 / -PPG THE COMPREHENSIVE SOLUTION FOR 200 MM (8"), 300 MM (12") AND 450 MM (18") PRIME WAFER PROCESSING AC 2000-PPG PRIME WAFER PLANETARY PAD GRINDING SYSTEM The unique and primary patented UPAC (Upper Platen Adaptive Control) system is the feature needed to maintain a parallel and stable gap profile between the upper and lower working wheel while processing wafers. Only the UPAC technology provides accuracy in gap adjustment to compensate for any wheel deflection caused by thermal expansion or force induced stress that is required to successfully perform Planetary Pad Grinding on double side machining tools. CUSTOMIZED SOLUTIONS FOR THE SEMICONDUCTOR INDUSTRY LAPMASTER WOLTERS is a well known, reliable partner for semiconductor customers in the Prime Wafer and LED Wafer manufacturing sectors. LAPMASTER WOLTERS is offering customized solutions for high-precision surface processing technology of wafers and substrates. Industries served are silicon, sapphire, gallium arsenide, silicon carbide, and other materials used for manufacturing microelectronic, microoptical and micro-mechanical devices. Our grinding, lapping, and polishing machines for all substrates up to 450 mm (18") provide process results defining the leading edge in terms of local and global geometries. “Made by LAPMASTER WOLTERS” signifies the highest quality in the international marketplace for machine tools. FROM SILICON TO WAFERS – THE AC 2000 FROM LAPMASTER WOLTERS With its third generation microLine© AC 2000, LAPMASTER WOLTERS is offering solutions for A large contact zone between wafer and grinding surfaces result in reduced local stress and a uniform grinding pattern. No center marks as known from conventional cup wheel grinders are created. The improved local and global wafer flatness after PPG, in combination with reduced sub surface damages result in shorter polishing times compared to conventional lapping or grinding. double-side grinding and polishing of wafers from a diameter of 200 mm (8") up to 450 mm (18"). As a result of its unique machine concept, AC 2000 is the most flexible machine for supporting all future wafer requirements. We are constantly setting a new benchmark in precision, quality, efficiency, and cost of ownership. Using the same tool platform for PPG and DSP helps reduce costs for operator training and maintenance. Surface geometry of wafer processed with LAPMASTER WOLTERS’ Planetary Pad Grinding Technology FIRST-CLASS CUSTOMER SUPPORT AND CONSUMABLES LAPMASTER WOLTERS offers customers first-class support for the entire lifecycle of their machine; for the highest machine availability and productivity as well as process, planning, and security backed by our worldwide network of qualified technicians and service specialists.
