Halbleiterkörpersubstrate
Halbleiterkörpersubstrate refers to the foundational material upon which semiconductor devices are built. It serves as the mechanical support and the electrical base for the active components of integrated circuits. The most common material used for semiconductor substrates is silicon (Si), due to its abundance, well-understood properties, and cost-effectiveness. Other semiconductor materials like germanium (Ge), gallium arsenide (GaAs), and indium phosphide (InP) are also employed for specialized applications requiring specific electrical or optical characteristics. The substrate must be a single crystal with a very high degree of purity and crystalline perfection. Impurities or defects in the substrate can significantly degrade the performance and reliability of the semiconductor devices fabricated on it. Substrates are typically processed into thin wafers, which are then subjected to a series of fabrication steps, including etching, deposition, and lithography, to create the desired electronic circuits. The choice of substrate material and its quality are critical factors in determining the capabilities and limitations of semiconductor technology.
