Ever since the invention of the transistor, the idea of making electronic components small was no longer a future prospect. It was now possible, especially with the invention of miniaturization, and silicon crystals. Scientists found a way to create circuits that were made with the electronic paths etched into the board, along with all the components required to make that circuit work, soldered in place. This was done by fabricating the integrated circuits by using vapor-phase deposition of semi-conductors, insulators, oxidation, solid-state diffusion, ion implantation, vacuum deposition, and sputtering. Integrated circuits were made for various types of products, but the most common ones were for computer and logic circuits.
