Most conventional methods for the extraction of substrate network were based on the use of frequency behavior of Y22 + Y21. However, we found that the feedback signal through the internal circuit elements makes the conductance of the substrate network underestimated while makes the susceptance of the substrate network overestimated. If conventional methods are directly performed on large area SiGe HBTs, a negative effective substrate resistance will be extracted. In the first part of the thesis, a new extraction method for the substrate network parameters of SiGe HBTs is proposed. When extracting the substrate network parameters, the feedback signal through internal circuit elements is considered. All the circuit elements of substrate network are extracted from Ysub instead of Y22 + Y21. The extracted substrate network parameters show a different bias dependence as compared to the conventional methods. By using a simple n+-p junction, we successfully explained the extracted bias dependent substrate network parameters. We developed a series linear regression equation to extracted the intrinsic circuit elements from the ABCD parameters. Compared with the conventional methods which extracted the circuit elements from Y-parameters or Z-parameters, the proposed method is much simple and easy to implement in the computer programs.

传统方法在萃取基板网路参数时，常常由所量得的Y22 + Y21来著手，但我们的研究发现，利用Y22 + Y21的频率关系来萃取基板参数时，基板网路的电导会被低估而基板网路的电纳则会被高估，另外传统基板网路参数萃取方法在萃取大尺寸元件基板网路参数时会得到负值基板等效电阻，以上的非理想效应皆因忽略部份信号会经由本质参数对基板网路做回授的影响，因此本论文中提出一个新的基板网路参数萃取方法，在萃取基板网路参数时考虑了由本质参数所回授的信号，并且由Ysub而非Y22 + Y21萃取基板等效电阻、基板等效电容及基板与集极空乏电容，成功的解决上述的一些非理想效应，所得到的基板网路参数与集极偏压的关系与传统方法所得的趋势相异，经由一个简单的模型成功的解释了所萃取得到的基板网路参数与偏压的关系，在萃取本质参数时，我们舍弃传统萃取方法中常用的Y参数或Z参数萃取方程式，而改用ABCD参数，并提出一系列的线性回归方程式，萃取所有的本质参数，与传统方法比较起来，比较简单而且容易建立在使用者的参数萃取软体中。
