Integrated circuits (ICs) - Combination of transistors, diodes, capacitors in a chip - Ultra large scale integration (ULSI) >1,000,000 components per chips - Morre s law: the number of transistors on a chip were doubling every 18 months - Intel four core Itanium CPU- Tukwila has over 2 billion transistors on a chip Courtesy of wiki
Si, Si, Si, why Silicon??? Silicon has smallest carrier mobility compared with Ge and GaAs. Drawback of Ge -Ge s device easily to leak at high temp. -GeO2 is water soluble -melting point of Ge is only 937 C Drawback of GaAs -hard to get high quality and large size wafer -need additional procedures to form dielectic materials Advantage of Si -Cheap raw materials, e.g., rock, sand, second most abundant element on earth, appear as SiO2 - High melting point: 1415C - stable silicon oxide (SiO2) as dielectric materials
Optoelectronic devices using semiconductors: Si III-V I-III-VI, many semiconductors are candidates LED (light emitting diodes) Laser Solar cell Photodetector
The band gap of semiconductor optoelectronic materials corresponding to a optical spectrum E=1.24/ (eV) When E: electron volts : m E= hc/ -direct band gap materials -Compound (II-VI, III-V, IV-VI) semiconductors
LED basic manufacturing processes ,3-76 Similar manufacturing process could be also applied to laser, solar cell industry
