8:30am-4:30pm, Wednesday, May 20, 2015, Marriott Uptown, Albuquerque, NM
- Mechanical, electrical, and optical properties of thin films
- Process parameters that affect film properties
- Gauge and instrument calibration
- Properties of substrate surfaces
- Measurement of film stress
- Detection of contamination
- Introduction to surface analysis techniques (Auger, ESCA, SIMS, FTIR)
- Substrate preparation and cleaning
Vacuum deposited thin films are used for optical coatings, electrically-conductive coatings, semiconductor wafer fabrication, and a wide variety of other uses. They may be deposited on glass, plastic, semiconductors, and other materials. Usually, a vacuum deposition process produces durable, adherent films of good quality. But what do you do when things go wrong? Not all films can be deposited on all substrate materials. Sometimes films peel off or crack. Other times they are cloudy, absorbing, scattering, or have other unacceptable properties.
This short course will teach you about techniques and tools that can be used to identify the source of the problems, correct the process, and get back into production. It will also help in learning how to develop new processes and products. The course is designed for process engineers and technicians, quality control personnel, thin film designers, and maintenance staff.
Who Should Attend?
This course is intended for process and equipment engineers, system operators, maintenance personnel, and others involved in thin film deposition processes.
