Lithography: How Chemists Make Tiny Computer Chips

Semiconductor chips are becoming increasingly smaller with greater computation capabilities. Lithography, a chemical/physical process, forms intricate patterns on chips by depositing materials through masks. In our daily lives, a parallel concept is found in screen printing graphic artworks on canvases or t-shirts. Engage in a hands-on activity to grasp lithography fundamentals using affordable materials like cardstock stencils and paint. Additionally, observe micropatterns created on chips in the lab using an optical microscope.
