2. The Moore's law states that the device (transistor) density of a microchip "doubles" every 2-3 years. Can you explain how semiconductor industry has been achieving this goal in terms of downscaling of a feature size (technology node)? (20 pts) Hint) What number did we end up when dividing a technology node of a certain year by that of a previous year (i.e., 2-3 years ahead)? 3. List and explain what are three main reasons that made Si (silicon) the winner in electronics. ( $20\mathrm{pts})$
