  • Method and apparatus for doping semiconductors
    Publication number: 20070254462
    Abstract: Semiconductor materials such as silicon particles are doped by mixing the semiconductor material with a solution having a dopan and a solvent. The solvent is removed from the wetted surface of the particles of the semiconductor material, thereby yielding particles that are substantially free from the solvent and are uniformly coated with the dopant.
    Type: Application
    Filed: April 20, 2007
    Publication date: November 1, 2007
    Applicant: Evergreen Solar, Inc.
    Inventors: Mary Cretella, Richard Wallace
