<br>
My name is David Catherall, I'm a research engineer at Caltech working towards solving various technical limitations of current PVD technologies. As part of the NSF I-Corps program, one of my fellow PhD students and I are doing a holistic investigation of PVD
tools, specifically those used for materials/device research and by small-scale production facilities. Our questions range from how purchasing decisions are made to specific processing challenges users may have faced and what solutions they came up with.<br>
<br>
We ask for only 15 minutes of time from people in various positions, including lab directors, tool managers, and end-users who are or have previously run into constraints with the existing tools available. We are also interested in talking to folks who may
have held these positions in the past, even if they now have different responsibilities.<br>
<br>
We would greatly appreciate talking with you to learn from experts in the field. We hope that through our discussions we can bring new innovations to the industry. That said, we do not have anything to offer at this time, and I want to be clear that this is<i>
not</i> a sales pitch.<br>
<br>
