Detailed explanation-1: -The birth history of semiconductors can be traced back to the invention of the rectifier (AC-DC converter) in 1874. Decades later, Bardeen and Brattain at Bell Laboratories in the US invented the point-contact transistor in 1947, and Shockley invented the junction transistor in 1948.
Detailed explanation-2: -The semiconductor industry is the aggregate of companies engaged in the design and fabrication of semiconductors and semiconductor devices, such as transistors and integrated circuits. It formed around 1960, once the fabrication of semiconductor devices became a viable business.
Detailed explanation-3: -During the development of semiconductor industry, silicon (Si), and germanium (Ge) are called the first generation of semiconductors. Gallium arsenide (GaAs) and aluminum arsenide (GaSi) represent the second generation of semiconductors.
Detailed explanation-4: -Third generation semiconductors-Gallium Nitride (GaN) and Silicon Carbide (SiC)-presents superior physical properties that could potentially replace the first and second generation semiconductor materials. Industry players are moving into the third generation semiconductors.
