Integrity-controlled compensated SoG silicon
| German title: | Integritäts-kontrolliertes kompensiertes SoG Silizium | |
| Acronym: | IKOSI | |
| Duration: | 1st May 2012 - 30th April 2014 | |
| Description: | The research project is divided into three parts. 1. Building on the knowledge base for EG silicon, a fundamental understanding of SoG silicon will be developed. Here, the influence of acceptor and donor compensation, impurities such as Ti, Ni, Mo, Cr and defect complexes such as iron-boron pairs (FeB), iron-aluminum pairs (FeAl), aluminum-oxygen (AlO) and boron-oxygen (BO) will be investigated. 2. Development of the measurement methodology for SoG silicon. 3. Evaluation of the measurement methods for application in the production of moca SoG silicon. K. Lauer, C. Möller, D. Schulze, T.
