Joint European Enterprise in Phase-Shift, Advanced Mask Technology: towards 0.25 micron

Objectif

After 12 months of work, the objective of JEEPS remains to investigate a wide range of factors concerning the design, specification, manufacture and use of phase-shift masks (PSMs) and their application to the production of 0.35 micron feature sizes using i-line lithography.
Simulation of 4 phase shift mask (PSM) types (rim, alternating, outrigger, chromeless) has been done. Experimental PSMs of these types have been manufactured and tested for the polysilicon (poly-Si) and contact layers.

Rim type and alternated (400 included in the project) PSMs have been selected for further investigations, chromeless PSMs have been dropped, as they produce only marginal performance benefits over conventional masks.

Intensive work has been carried out in the field of mask qualification and repair.
The main deliverables planned are:

- a process for PSM manufacturing, now focussed on attenuated and rim-type PSMs,
- application recipes for the use of PSMs
- masks and application wafers, with appropriate specifications
- a industrial manufacturing concept for PSMs.

As part of the development of a manufacturing concept, costs and turnaround time of i-line lithography in combination with PSMs will be estimated in comparison with DUV lithography without PSM techniques.

Exploitation of the results will be ensured by establishing sample manufacturing capabilities for phase shift in several places in order to supply PSM technology to industry and research institutes.
