In this paper a hybrid algorithm that incorporates the genetic algorithm and the traditional Powell algorithm with the applications to the semiconductor device model parameter extraction is presented.

Equivalent circuit model and parameter extraction of on-chip planar spiral inductors on silicon substrates;

Distributed inductance and resistance parameter extraction of 2D multi chip module interconnection;

A new parameter extraction method for HBT′s small signal model;

Superquadric parameters extraction is essential for superquadric_based reconstruction from 2D images and 3D data, but most of the search algorithms for superquadric parameters extraction are suboptimal and they are susceptible to being trapped into local optima.

Though a review of high fidelity wave-field separating technology, 3D VSP parameters extraction , imaging method in the processing , the author discuses the problems in the 3D VSP processing and some of the key processing techniques applied and proposes the development trends of the technology.
