Section II: Object
Electron-Beam Evaporation System
This tool supply is concerning an Electron-Beam Evaporation system for thin-film deposition of various metal layers (single/multiple) on various substrates, typical 2”, 4”, and 6” wafers for device fabrication based on top-down micro/nano technology. High uniformity as well as avoiding sidewall deposition for lift-off processes and a high throughput is essential.
The tool should provide high-throughput solutions (total processing time < 15 min (process start at 5x10-6 Torr), including load/unload) for single wafer as well as larger wafer batches (4 substrates of up to 150 mm) for small-scale production. Moreover, the tool should cover multiple metal stacks depositions (up to ten different metals at a time).
A main application of the metal layer stacks is structure definition by lift-off, where it is essential to obtain highest possible control of uniformity and avoid sidewall deposition on the defined photoresist structures. For this particular application FerroTec-Temescal has developed a unique patented solution (US Patent# US9281231) named High-Uniformity Lift-off Assembly (HULA dome) which is a magnetically driven planetary motion substrate holder, in a lift-off configuration with up to 4 substrates of up to 150 mm, rotating individually on two axis, which can provide the high uniformity metal layer stack depositions without shadow masks which tends to be the standard solution in other systems. With the HULA system it is possible to deposit metal layer stacks with better than 2% uniformity and avoid sidewall deposition, with no shadow mask. Moreover, deposited material uniformity is independent of deposition rate, giving a wide process window.
The Temescal machine with the HULA system offers a completely unique approach to deposition of highly uniform metal stacks. Other manufacturers resort either to a very long distance from crucible to sample or to using shadow masks. The long distance leads to excessive waste of material which is a particular concern when dealing with expensive noble metals such as gold or platinum. Shadow masks must be designed for specific materials and specific deposition conditions and thus starkly limit the process window available for depositions. All in all the HULA option provides an efficient solution for reduced material consumption and maximum process window. Further advantages of evaporation without a mask are higher effective deposition rates, leading to faster cycle times and superior material collection efficiency, which is especially important when depositing expensive precious metals, such as Au & Pt. Moreover, the magnetically driven planetary motion substrate holder prevents the release of fine metal particles originating from moving parts in ordinary contact-drive gear systems during deposition. The contamination of metal particles from moving parts can be destructive for our applications, especially for deposition of very thin layers.
Section IV: Procedure
- The works, supplies or services can be provided only by a particular economic operator for the following reason:
- protection of exclusive rights, including intellectual property rights
Given DTU’s strict requirements for this equipment concerning minimum waste of material, uniformity and avoidance of sidewall deposition combined with a short process time, this lift-off technology is considered the only relevant for DTU. Furthermore, the unique magnetically-driven HULA system prevents the release of fine metal particles from the planetary motion substrate holder which is critical for DTU in order to avoid contamination of the deposited thin films. The equipment can only be purchased from FerroTec-Temescal due to patent rights.
