The papers included in this issue of ECS Transactions were originally presented in the symposium ¿High Purity Silicon 11¿, held during the 218th meeting of The Electrochemical Society, in Las Vegas, Nevada from October 10 to 15, 2010.

The issue of the 10th High Purity Silicon symposium provides an overview of the latest developments in the growth, characterization, devices processing, and application of high purity silicon in either bulk or epitaxial form. The emphasis is on the control and prevention of impurity incorporation, characterization and detection of defects and impurity states in high purity and high resistivity silicon for superior device performances. Device and circuit aspects related to the application of devices fabricated on high resistivity silicon wafers will also be addressed. Special attention will be given to alternative and high-mobility substrates and their material and device aspects.

"... papers that were presented at the Sixth Symposium on High Purity Silicon held in Phoenix, Arizona at the 198th Meeting of the Electrochemical Society, October 22-27, 2000."--Preface.

This issue discusses the latest developments in the growth, characterization, device processing and applications of high-purity silicon in either bulk or epitaxial form. Information is given on the control and prevention of impurity incorporation, characterization and detection of defects and impurity states. Device and circuit aspects are also covered. Advanced substrates such as SOI, strained Si and germanium-on-insulator are discussed.
