Understanding Compound Semiconductors

Compound semiconductors have excellent performance and a broad development prospect. Compound semiconductors mainly refer to second and third generation semiconductors such as Gallium Arsenide (GaAs), Gallium Nitride (GaN), and Silicon Carbide (SiC). Compared to the first generation of elemental semiconductors, they are significantly superior in high-frequency and high-temperature performance. Gallium Arsenide: It features high frequency, … Read more

Comprehensive Introduction to Semiconductor Wafers

Source: Semiconductor Industry Alliance A wafer is a fundamental raw material for manufacturing semiconductor devices. Extremely pure semiconductors are prepared into wafers through processes such as crystal pulling and slicing. The wafers undergo a series of semiconductor manufacturing processes to form extremely small circuit structures, which are then cut, packaged, and tested to become chips, … Read more

Focusing on Key Industrial Chains: Understanding Compound Semiconductors and Opportunities

Semi-conductor materials can be divided into two categories: elemental semiconductors and compound semiconductors. The former includes semiconductors formed from elements such as silicon (Si) and germanium (Ge), while the latter includes compounds such as gallium arsenide (GaAs), gallium nitride (GaN), and silicon carbide (SiC). In the past, semiconductors have undergone three generations of changes, gallium … Read more
