We are continuously striving to increase the number of transistors on a chip to increase performance. The drive for smaller and faster technologies has caused the development of fabrication techniques that allow us to work at the nanoscale feature size. A few lithography techniques will be explored to show how this whole process works. The processes I will cover include Photo, Electron Beam and X-Ray lithography. These forms of lithography share a common process of preparation exposure and development while fabricating wafers.. NANO 101. Introduction to Nanotechnology. 1. 2. Lithography. Photolithography.
