CNS Nanofabrication Summer School 2026

CNS Nanofabrication team will provide a series of tutorials on nanofabrication technologies. Two classes every week will not only cover the fundamentals of nanofabrication technology, but also the process tips/tricks, and related frontier research and applications. All CNS users are eligible to attend. The certificate will be awarded to any attendee who takes 8 or more courses!

Location: 100 Geo Lecture Hall, 24 Oxford St., Cambridge MA, 02138,
Time : Tuesday/Friday, 12:00-1:30pm,
Pizza lunch will be provided. The agenda may be changed according to the availability of staff and vendors.
