The IPEC 472 wafer polisher is a fully automated, precision tool for CMP polishing of semiconductor wafers used to achieve flatness, uniformity and planarization on patterned/device wafers. The 472 features automatic wafer handling and is capable of two platen, two-step polishing processing to maximize wafer throughput capability and quality. Designed to planarize wafers from 100mm to 200mm, the 472 is ideally suited for materials polishing applications that require repeatability with operational and processing flexibility. Only Axus Technology is authorized to provide ViPRR carrier upgrades for refurbished IPEC 372M and 472 CMP tools. We now offer a membrane carrier upgrade for 4” through 200mm wafers, using the Titan and Axus-T4 carrier upgrades. We also continue to provide upgrades and support for ViPRR carrier upgrades. The IPEC 472 supports a number of conditioner and carrier upgrades.
