This document contains exam questions and answers about integrated circuits and microelectromechanical systems (MEMS) fabrication processes. Question 1 asks about (a) Gordon Moore's predictions for increasing computing productivity and cost, (b) classifications of integrated circuits based on circuit function, and (c) the differences between bulk micromachining, surface micromachining, and LIGA MEMS fabrication processes.

Question 1 a) state two(2) predictions made by Gordon E. Moore to increase the productivity, cheap and computing . states that processor speeds, or overall processing power for computers will double every two years. stated that the number of transistors on an affordable CPU would double every two years
b) intergrated circuit (IC) can be classified into three categories which are fabrication method,transistor type and circuit function Explain intergrated circuit classification based on the circuit function Analog circuits are circuits dealing with signals free to vary from zero to full power supply voltage. This stands in contrast to digital circuits, which almost exclusively employ all or nothing signals: voltages restricted to values of zero and full supply voltage, with no valid state in between those extreme limits. Digital circuits are circuits dealing with signals restricted to the extreme limits of zero and some full amount
c) differentiate between the three of MEMS fabricaton process (Bulk micromachining, surface micromachining and LIGA. Bulk micromachining Can be done much faster Can make high aspect ratio parts Cheaper surface micromachining Mechanical properties of most thin- films are usually unknown and must be measured Reproducibility of mechanical properties can be difficult More expensive
Lithographie Galvanoformung Abformung (LIGA) Relatively new technology Enables very high aspect ratio etches Uses high density plasma to alternately etch and deposit etch resistant polymer on sidewalls
