Pure-play foundries like TSMC (Taiwan Semiconductor Manufacturing Company) manufacture chips for fabless designers. TSMC produces the vast majority of the world's advanced processors.

While the diode is a powerful two-terminal device, the true building block of the digital age is the , a three-terminal semiconductor device. TSMC produces the vast majority of the world's

The wafer is diced into individual chips, tested, and packaged. 5. Applications of Semiconductors Computing: CPUs, GPUs, RAM, and SSDs.

Impurities are introduced into specific areas to change conductivity. Gallium Arsenide (GaAs) High speed

Replaces copper wires inside chips with light pulses (photons). This dramatically increases data transfer speeds while lowering power consumption and heat generation.

A seed crystal is pulled using the Czochralski process to create a large, single-crystal cylindrical ingot (boule).

While Silicon remains king, different applications require different atomic properties. Key Benefits Primary Use Cases Abundant, cheap, highly stable native oxide layers. CPUs, GPUs, RAM, general logic gates. Germanium (Ge) Faster electron mobility than silicon. High-speed fiber optics, infrared optics. Silicon Carbide (SiC) High thermal conductivity, handles extreme voltages. Electric vehicle (EV) inverters, power grids. Gallium Nitride (GaN) High electron mobility, handles high frequencies. Fast chargers, 5G RF amplifiers, LEDs. Gallium Arsenide (GaAs) High speed, generates light efficiently. Satellite communications, laser diodes. 4. The Semiconductor Fabrication Process
