Canon FPA-6300ES6a KrF Scanning Lithography System

The Canon FPA-6300ES6a is a high-resolution KrF scanning lithography system designed for high-volume manufacturing. Released in 2012, it is primarily used in the production of memory devices (such as DRAM and flash memory), logic chips, and image sensors. Its core value lies in achieving an optimal balance between high productivity and industry-leading overlay accuracy on mature DUV (deep ultraviolet) process nodes.

Key Specifications: It utilizes a KrF 248nm light source and features an automatically variable numerical aperture (NA) ranging from 0.50 to 0.86. It offers a resolution of ≤90nm, an exposure field of 26mm × 33mm, and supports both 200mm and 300mm wafers.

Performance Highlights: Through the implementation of a new wafer stage and optimized alignment sequences, the system achieves a throughput of over 200 wafers per hour for 300mm wafers (with specific options), representing an approximately 1.6-fold increase over the previous generation. In terms of overlay accuracy, the system employs high-precision temperature control and synchronization technologies to achieve a mix-and-match overlay (MMO) accuracy of ≤5nm (with specific options)—a top-tier performance level for KrF scanners of that era.

Market Positioning: Built upon the mature FPA-6000 platform, this model emphasizes a low cost of ownership and production line continuity. It is well-suited for mature manufacturing processes that do not require extreme resolution, but instead prioritize stable, high-volume production efficiency.
