Biot theory research has been extended to the multi-scale heterogeneity in actual rocks. Focused on laboratory frequency bandwidth studies, we discuss the relationships between double-porosity and BISQ wave equations,...
A new 125mm UHV/CVD SiGe/Si epitaxy equipment SGE500 capable of commercialization is constructed and device-level SiGe HBT material is grown.A polysilicon emitter (PolyE) double mesa microwave power SiGe HBT showing e...
A sub circuit model for VDMOS is built according to its physical structure.Parameters and formulas describing the device are also derived from this model.Comparing to former results,this model avoids too many technic...
