Used DNS / DAINIPPON 80A #293830591 for sale

DNS / DAINIPPON 80A is a photoresist equipment which enables users to accurately expose patterns on wafers. This system is distinguished by its high stability, accuracy, and additional multifunctional functions. The unit consists of an exposer head module, an optical machine module, and a mechanical components module. The exposer head module contains two independent symmetrical alignment eyes. Each of these eyes features an accurate auto-alignment capability with a resolution of 2um and 0.1 um repeatability. The resolution is also adjustable from a range of 0.5um to 3um. Additionally, two mirrors are included in the exposer head module to allow for an even distribution of light across the entire wafer. The optical tool module is designed to allow for efficient illumination of the masks onto the wafer. It utilizes a large-diameter illumination optical asset which is designed to be used in combination with various lenses, such as 25 mm and 50 mm. This model produces a bright-field illumination with a homogeneous light intensity on the wafer. Additionally, the optical equipment module features a local galvanometer scanner and a rotation stage for scanning large areas of the wafer at one time. The mechanical components module works with the optical system module to accurately position the wafer. It features a positioning guide for precise location of the wafer and a wafer chuck to ensure that it is stable. Additionally, the mechanical components module includes a height adjustment feature to control the exact distance between the aligner head and the wafer. DNS 80A photoresist unit offers a reliable and accurate approach to patterning wafers. This machine meets the requirements of many different types of applications due to its high stability, accuracy, and additional multifunctional functions. With its advanced features and functions, the tool is ideal for patterning a wide variety of wafers quickly and accurately.
