High Performance Electron-beam Lithography System SB254

Vistec’s SB254  is a fully automated, high performance, cost-effective electron-beam lithography system designed for use in both industry and advanced research. Based on the Variable Shaped Beam (VSB) principle, these tools are utilized in a wide range of existing and emerging semiconductor and nanotechnology applications including silicon direct write, compound semiconductor, mask making, integrated optics, and silicon photonics.

The Cell Projection feature (optional) enhances throughput and pattern fidelity of repetitive or curvilinear structures.

Fully automated substrate handling, adjustment and alignment allow operation without manual interaction. The lithography system is compliant to semiconductor production environments and prepared to remote monitoring and control according to SEMI equipment automation standards.
