Semiconductor crystallization on composite polymer substrates

摘要

A structure and methodology for providing electronic devices comprised of semiconductor materials deposited and crystallized using a pulsed laser source on oxide and/or metal layers on polymeric and polymer composite substrates of low coefficient of thermal expansion (CTE). The present invention permits the fabrication of inexpensive yet highly efficient electronic devices, such as photovoltaic cells, on the filled substrates by the use of laser annealing techniques.
