Vistec SB250 series

Overview

The Vistec SB250 electron beam lithography system has been designed as a universal and cost-effective tool for both direct write and mask making applications to allow the customers to react quickly to market demands.

With its 210 x 210mm stage travel range it is the ideal tool for exposing masks up to 7 inch and wafers up to 200 mm diameter.

The concept of the SB250 enables handling and exposure of transparent and non-transparent compound semiconductor materials. The modular system architecture allows your SB250 to be easily upgraded to a higher tool performance.

The small cleanroom footprint and the fully automated substrate handling as well as the state of the art operating and data preparation software will convince you of the excellence of the SB250 Series being part of the modular toolset Vistec is offering to its customers from the industry and applied research sector.

The field-proven VSB (Variable Shaped Beam), "Write-on-the-fly" and Vector Scan writing modes as well as the 50keV shaped-beam column are further highlights of the new SB250 series.
