Abstract
SiO2 spin-on films of various concentrations of 1, 2, 6, 22 and 36 at. % zinc have been fabricated and used for the p diffusion into undoped n-type InP. An increasing zinc concentration (N-0) of the spin-on film leads to a higher atomic zinc concentration (N-Zn) and diffusion dept h in InP. From the experimental results a distribution coefficient N-Z n/N-0 of 0.012 has been determined. A higher atomic zinc concentration in InP results in a lower acceptor concentration. With additional hea t treatment the electrical activity of zinc can be increased significa ntly.
