HERCULES®

Lithography Track System

The HERCULES® is a high-volume platform integrating the entire lithography process flow in one system, reducing process footprint and operator support.

Based on a modular platform, the HERCULES combines EVG’s established optical mask alignment technology with integrated wafer cleaning, resist coating, baking and resist development modules. The HERCULES enables cassette-to-cassette processing of various wafer sizes. The HERCULES safely handles thick, highly bowed, rectangular, small-diameter wafers or even device trays. Precision top-side and bottom-side alignment as well as coating of sub-micron to ultra-thick (up to 300 microns) resists can be applied for interlayer and passivation applications. The superior alignment stage design achieves highly accurate alignment and exposure results at high throughput.

Features

  • Production platform combines all advantages of EVG’s precision alignment and resist processing systems in a minimized footprint
  • Versatile platform supports fully automated processing of various substrate shapes, sizes, highly warped mold wafers and even trays
  • Coating of up to 52,000 cP enables manufacturing of ultra-thick resist features of up to 300 microns in height
  • CoverSpinTM rotating cover for low resist consumption and optimized resist coating uniformity
  • OmniSpray® coating for optimized coating of high topography surfaces
  • NanoSpray® for coating and protection of via structures
  • Automated mask handling and storage
  • Optical edge exposure and/or solvent cleaning for edge bead removal
  • Fragile, thin or warped wafer handling of multiple wafer sizes with bridge-tool system
  • Rework sorting wafer management and flexible cassette system
  • Multi-user concept (unlimited number of user accounts and recipes, assignable access rights, different user interface languages)
