Raith Turnkey 150 SEM & E-beam lithography system

Repsonsible: Anders Liljeborg

Good bye Raith 150, dismantling the tool

The SEM (Scanning Electron microscope) and e-beam lithography system from Raith Gmbh was delivered on 28:th of May, 1999. It is a combination of a SEM manufactured by LEO Electron microscopy Ltd. (now acquired by Zeiss) using the Gemini column and a high precision laser interferometric stage combined with special D/A (digital-to-analog) converters for the e-beam deflection during lithography, both made by Raith Gmbh.
