What’s happening? We’d love to hear how your internship is going! I am working on photolithorgraphy in Professor Cheng’s lab under Bryn Mawr Physics Department this summer.

Nanostructured materials are materials with one or more dimensions at nanoscale. Our lab focuses on magnetic properties of nanomaterials and their possible applications in digital storage and sensors. By applying photoresist to silicon wafers and using Mask Aligner we are able to grow patterns on samples in UV light exposure.

The picture shows how silicon wafers look like after applying photoresist.

We are now working on the sample fabrication and optimization. We are also measuring the thickness of photoresist and develop different patterns. Next week we are heading to Argonne National Lab to do some experiments!
