At Semicon I met with Applied Materials to learn about epitaxy. This is when a monocrystalline film is grown on the substrate which takes on a lattice structure that matches the substrate. It forms a high purity starting point for building a transistor and is also the basis of the strain engineering in a modern process.

In the last few decades, electronics has become more and more central to our lives. When I was a child the only electronics in the house was the radio and the television, both of which contained tubes. Two big things happened that upended that world: the invention of the transistor and the invention of the integrated circuit. A modern… Read More
