Lithography: How Chemistry Creates Tiny Computer Chips

Semiconductor chips are becoming increasingly smaller with greater computation power. Lithography is a chemical/physical process that creates small patterns on chips by depositing materials through physical masks. In our everyday lives, screen printing of graphic artworks on canvases or T-shirts utilizes a similar concept. Using a hands-on activity, learn the basics of lithography using inexpensive materials like cardstock stencils and paint. Also, see actual micropatterns fabricated on chips in the lab.
