Photolithography Consulting

and Coaching

About Us

Photolithography.net is a company which specializes in semiconductor photolithography and all front end semiconductor optimization and troubleshooting by paid coaching and consulting. We can help with any lithography or other semiconductor issue including defect, exposure tool and coater track issues.

Collectively we have years of fab experience which includes technologies such as g-h-i-line, Krf, Arf, EUV, E-beam, registration and defect investigations. Our services can be obtained by a PO from any semiconductor company. You can contact us by calling 503-608-7611 or use our contact form. We strive to return your call or email as soon as possible. Our normal response time is within 1 hour. We are also much less expensive than hiring a new Engineer. We can provide onsite Engineering service while you look and interview candidates. We can train new engineers.

Dave White

I have 25 years as a Lithography Engineer plus 10 years consulting. Intel, then Micron, then Fujitsu then TOK Photoresist. Now Consulting for Photolithography.net. I have worked on all areas of lithography. Including ASML EUV. I have co-authored a SPIE poster paper on ArF double patterning with Dr. Tom Wallow in 2007. I am interested in helping any semiconductor company with their litho needs whether g-line or advanced litho. I have worked inside the following companies cleanrooms. Seagate hard drive head and media sites, Cypress, HGST, Polar Semi, Western Digital, Linear Tech, Texas Instruments, Intel, Freescale, SVTC, Microchip, Spansion, and Maxim. Also, The effect of resist dissolution process on pattern formation variability:

Helped Significantly

I had the opportunity to utilize Dave’s assistance on a new photochemical for a specific application. Dave was able to recommend a plan of action and share his experience on the chemical, this helped significantly with implementing it in production and with shortening the qualification required.

Extremely Helpful

I worked with Dave on resist evaluation. He has demonstrated an incredible customer service, very friendly and easy to work with. His strong dedication on product supports is excellent. He is very fast responding to any inquiries, questions or issues, no matter day or night, followed up all the way to make sure the inquiries or issues have been met or resolved. He was always willing to put more time outside than his normal
work schedule when he visited our factory to help expediting the resist evaluation process. More important his strong knowledge in photolithography process, resist materials and experience have been found extremely helpful for me in trouble shooting, providing very effective feedback to resolve any issues that we encountered. I strongly believe that Dave would be a great asset for any organization.

Consistent Support

Dave provided consistent support for our photoresist conversion project starting. Dave’s ability to draw on his experience and willingness to work with us in the wafer fab were valuable to help keep this project moving. Dave has a good understanding of photolithography processing and was a strong resource for detailed information about the photoresists and the details of photoresist processing.
