[0002] Integrated circuit boards are made using semiconductor manufacturing technology. Many transistors, resistors, capacitors and other components are made on a smaller single-crystal silicon wafer, and the components are combined into a complete electronic circuit using multi-layer wiring or tunnel wiring methods.
