- Alternate Title: Effect of silicon doping on aluminum nitride films with different substrates. (English)
- Abstract: Silicon is selected as the N-type impurity. Experimental study was performed by high temperature thermal diffusion. Pure silicon is deposited on the prepared AlN thin films on Si/Al
2 O3 substrate by magnetron sputtering. The sputtering time of silicon determines the thickness of the silicon layer, thereby determining the doping dose of silicon. After high temperature (1150℃) thermal diffusion under nitrogen atmosphere for 4 hours, silicon atoms on the surface of the AlN thin films are forced into the AlN lattice to replace the position of aluminum atoms to form silicon doped AlN thin films. Effective silicon doping causes the AlN (002) diffraction peak to shift towards a large angle. Higher silicon dose makes greater shift angle. Energy Dispersive Spectrometer tested results indicate that the substrate silicon will act as a fixed diffusion source and diffuse into the film, increasing the unintentional doping concentration, so the silicon element can be measured in the whole area of the film cross section. The sample of the sapphire substrate shows cracks after thermal diffusion.
