As wafer uniformity requirements tighten and vertical scaling increases, the need for CMP processing grows across market segments. Logic introduces new transistor designs and materials, DRAM incorporates new materials and process steps to planarize, and 3D NAND adds more decks, stacks and tiers.
The IMPULSE V system, available as an integrated or standalone platform, enhances film measurement fidelity and productivity for the CMP process module. With deep ultraviolet (DUV) optics and AI-driven machine analytics derived from our Atlas® platform, it works in conjunction with the Atlas® platform to provide CMP process engineers the capability to manage excursions and drive process improvement (Cpk.).
Advanced wavefront technology suppresses previous layer noise in complex structures. It provides feedback to improve long term repeatability. Designed for higher sampling, in-die/on-device and wafer edge measurements, the system offers improved reliability, higher throughput and over 2X precision improvement compared to the previous generation. Onboard AI-driven machine learning uses a signal-to-noise ratio for faster time-to-solution, addressing layers that were previously challenging to measure.
