In top-down micro- and nanomachining, this is done by building down fiom bigger chunks of material; in bottom-up nanochemistry, it is by building up fiom smaller building blocks. Lithography uses oil or fat and gum arabic to divide the smooth surface into hydrophobic regions which takes up the ink and hydrophilic regions which does not and thus become the background. In general, the various processes used to make an IC fall into three categories: film deposition, patterning, and semiconductor doping. Describe the Fick’s law for Diffusion process.
