Metrology System
Aspect - Onto Innovation
Memory density increases with both layer-pair scaling and tier stacking for memory stacks well over 200 pairs. The Aspect metrology system was designed with these future architectures and scaling strategies in mind. Aspect metrology is demonstrating performance superior to X-ray systems across multiple customer devices through a revolutionary infrared optical system providing full profiling capability to enable critical etch and deposition control, with the speed and process coverage that customers require.
