E-Beam and Optical Lithography

Electron Beam Lithography (EBL)

RAITH EBPG5150 EBL

The EBPG5150 electron beam lithography system is designed for high-resolution and high-accuracy patterning of devices on semiconductor wafers. Highly focused electron beams are used to draw circuit patterns on the nanometer scale onto semiconductor wafers coated with resists.

  •  High current density Thermal Field Emission gun for operation at 20-100 kV
  •  155 mm platform
  •  Minimum feature size of less than 8 nm
  •  Rapid exposure with 50 or 100 MHz pattern generator
  •  Continuously variable large field size operation to 1 mm at all kVs
  •  GUI for ease of use operation for diverse “multi user environment”
  •  Thermal Field Emission (TFE) electron source
  •  Automatic dynamic off-axis focus, stigmation and distortion correction software
  •  Low noise 20-bit main field deflection
  •  Field size operation, variable up to 1mm by 1mm at all voltages
  •  Binocular microscope, X/Y stage and Laser Height sensor to pre-align wafers 
  •  System control software suite “BEAMS” on fully integrated control PC.

Mask Aligner

EVG 610 Mask Aligner

The EVG 610 is a semi-automated system that can handle small substrate pieces and wafers up to 200 mm. The tool supports lithography processes, such as vacuum-, soft-, hard- and proximity exposure mode, as well as other specific applications, including bond alignment, nano imprint lithography (NIL) and micro contact printing.

  • Supports back side lithography and bond alignment processes when configured with bottom side microscopes
  • Sub-micron exposure gap repeatability in proximity exposure mode
  • Unmatched exposure light uniformity at wafer level, down to ± 1.5% for small substrate applications
  • Windows based user interface
