The most important educational outcome of a laboratory oriented course on integrated circuit fabrication is finding out how well the devices created perform relative to the target specification. This is typically done through electrical stimulation and measurement on many devices to provide a statistically accurate picture of the resultant circuit performance. Our students have controlled the process from physics concepts, simulation, geometrical layout, fabrication sequence design, fabrication and then to testing. Mentally linking final device performance and device yield to student choices made throughout the process give our students superior preparation to enter graduate programs or industry. Our students design, make and test more devices as undergraduates than most PhD students ever make.
