Duane, << UT announcement and below .18u processing >> DPMI has a winner. Sub .18 was previously projected as needing X-ray or ebeam processing, significantly requiring excessive upgrade costs for processing. Although the mask costs are much higher than I realized, it's cheap when one considers no other equipment upgrades are necessary. I believe current Deep UV is 193 nanometers. Dropping to the near 50 nanometer range puts you into x-ray, a hole new safety factor. If DUV can be accomplished with these new masks, that I admit of no knowledge to how they're made, DPMI, hopefully holding the patent, will walk semis well into the future. I'm tempted to pump a TI fellow friend at TI on the subject of these masks. It's his field in .15 and below development. It would really be better if we could get inputs from a DPMI employee on the project. I'm sure the concepts are public info, but my curiosity now has me intrigued. Later -- Larry
