چکیده انگلیسی
Highly oriented AlN films are successfully deposited on B+ implanted Si(1Â 1Â 1) substrates in a radio frequency inductively coupled plasma (RF/ICP) system. The implanted energy and dose used for the B+ implanted Si(1Â 1Â 1) substrates are 200Â keV and 1015Â cmâ2, respectively. The c-axis texture of AlN films can be affected by RF gun power and ion implantation. Experimental results show that the full width at half-maximum (FWHM) of AlN(0Â 0Â 2) in the X-ray rocking curve measurements decreases with increasing RF gun power. The optimum condition is at 500Â W, where the FWHM of the AlN films deposited on Si(1Â 1Â 1) with and without B+ implantation are 2.77 and 3.17, respectively. In average, the FWHM of the AlN films on B+ implanted Si(1Â 1Â 1) are less than those on Si(1Â 1Â 1) by a factor of â¼10%. The enhancement of c-axis of AlN films due to B+ implantation is attributed to the reduction of AlN grains. Raman spectra also suggest that ion implantation plays a role in reducing the tensile stress in AlN films deposited on B+ implanted Si(1Â 1Â 1).
