JetStep G35 System

High resolution imaging; a step-and-repeat photolithography panel printer for display products

Designed for flexibility, the JetStep® G35 System utilizes a family of high performance projection lenses to enable high-resolution imaging as low as 2.5µm or up to 5µm under actual manufacturing conditions. A high power lamp provides an increased illumination intensity. Both image field stitching error and total overlay accuracy are specified to meet the most stringent production requirements on up to generation 3.5 substrates.
