Today, Onsemi announced on its official website that it has reached an agreement with Qorvo to acquire the SiC JFET technology business and Qorvo's subsidiary.

Chemical Vapor Deposition (CVD) is a versatile thin-film deposition technique widely employed in the semiconductor industry for fabricating high-quality, conformal thin films on various substrates. This process involves chemical reactions of gaseous precursors onto a heated substrate surface, resulting in the formation of a solid thin film. This article delves into the intricacies of CVD, exploring its mechanisms, advantages, limitations, and key applications in semiconductor manufacturing.

Isostatic graphite is a type of graphite with an ultra-fine grain. It is used for applications where the mechanical properties of other fine-grained graphites are inadequate.

Within the silicon carbide (SiC) industry chain, substrate suppliers hold significant leverage, primarily due to value distribution. SiC substrates account for 47% of the total value, followed by epitaxial layers at 23%, while device design and manufacturing constitute the remaining 30%. This inverted value chain stems from the high technological barriers inherent to substrate and epitaxial layer production. Three major challenges plague SiC substrate growth: stringent growth conditions, slow growth rates, and demanding crystallographic requirements. These complexities contribute to increased processing difficulty, ultimately resulting in low product yields and high costs. Furthermore, the epitaxial layer’s thickness and doping concentration are critical parameters directly impacting the final device performance.

Gallium Nitride (GaN) is an important material in semiconductor technology, known for its exceptional electronic and optical properties. GaN, as a wide-bandgap semiconductor, has a bandgap energy of approximately 3.4 eV, making it ideal for high-power and high-frequency applications.

The recent announcement of the 2024 Nobel Prize in Physics has brought unprecedented attention to the field of artificial intelligence.
