关于碳化硅晶体碳化硅(SiC)是Ⅳ-Ⅳ族二元化合物, 也是元素周期表Ⅳ组元素中唯一的稳定固态化合物, 是一种重要的半导体材料。 它具有优良的热学、力学、化学和电学性质, 不仅是制作高温、高频、大功率电子器件的优质材料之一,也可以用作基于GaN的蓝色发光二极管的衬底材料。目前用于衬底的碳化硅以4H为主,导电类型分为...
On the one hand, silicon carbide substrate wafer fabrication technology is mature, and the SiC wafer cost is competitive currently. On the other hand, the trend of intelligence and electrification continues to evolve. The traditional cars has brought huge demand for SiC power semiconductors. Thus,...
Planar (001)Si/(0001) Si-terminated 6H-SiC interfaces were synthesized by UHV diffusion bonding of cleaned, on-axis and vicinal wafers at 1100掳C for 5 hours, at MPa pressure. The interfaces were crystalline up to their defining plane, without nanospectroscopically detectable impurities. The ...

The surface barrier detector is a p-n type silicon diode wafer characterized by a rather thin depletion layer (Fig. 8.12(a)). It is made of n-type silicon on which one surface has been etched prior to coating with a thin layer of gold (typically ∼40 µg/cm2) and the other sur...
The DBRs, each composed of 3 alternating layers of SiC and Al(Ga)N grown on Si substrates, show high wafer uniformity with a typical maximum reflectance of 54% in the blue spectrum and a stopband (at 80% maximum reflectance) as large as 100nm. Furthermore, high vertical electrical ...
“For GaN RF market, GaN-on-SiC is the main technology platform,” said Ezgi Dogmus, lead analyst at Yole Intelligence. “Owning to their high bandwidth and efficiency, GaN-on-SiC devices keep taking share from LDMOS in the 5G market and are starting to benefit from the 6-inch wafer pl...
Residual stress of the deposited 3C-SiC layers was investigated across the entire wafer substrates by using Raman spectroscopy and values between 0.5 and 1 GPa were found. It was observed that, for a given carburisation procedure, the crystalline orientation of the Si substrates plays an ...
