The students learned about the fabrication of silicon-based devices and how silicon wafers are produced. Additionally, they had hands-on experience in the cleanroom and used the photolithography process to transfer a pattern on a photomask to a silicon wafer. The pattern had a scale on it from 100 um (diameter of a human hair) to 1 um (diameter of bacteria) to allow the students to understand the scale that MFF users work at.
The students also hand cleaved silicon wafers to produce dies of gold Michigan Tech logos as a keepsake for their time in the MFF. A similar event is planned for another SYP group this Tuesday (July 25).

Students experience day in Microfabrication Facility
HOUGHTON — Michigan Tech’s Microfabrication Core Facility provided students with a glimpse of the microfabrication process.
The students suited up and worked in the cleanroom to learn about fabricating silicon-based products. At the end, silicon wafers were transformed into dies of gold Michigan Tech logos through the process of photolithography.
