Changing the electrical properties in a material so that it is precisely what you want it to be in order to make a better computer chip is just taking the next step, although it's a very big step. If you're clever and mix various substances in precisely the right proportions, you can make the electrons in a semiconductor behave as if they were part of an element that isn't really there, or even part of a hypothetical element that doesn't exist in the real world.
