摘要: 研究了扩散源的浓度与掺杂后硅材料补偿度之间的关系。以MnCl2·4H2O乙醇溶液为扩散源,涂在初始电阻率为3.8?·cm的p型单晶硅片表面,在高温(1200℃)下掺杂锰后,在室温避光条件下,用SDY—5型双电测四探针仪测样品电阻率ρ。改变扩散源的浓度重复实验,用XRD对扩散后的样品进行分析,结果表明:当硅片表面浓度为23.4×10 8mol/cm2时,扩散后样品体电阻率的径向不均匀度在5%以内,扩散后硅片的补偿度最大。
英文摘要: MnCl2 ? 4H2O ethanol solution was daubed to a surface of p-type single crystal Si disc of 3.8 Q. ? cm as a Mn dopant source, and the sample was heated at 1 200 °C to do Mn diffusion. Experiments were repeated by changing concentration of the solution and obtaining different surface density of daubed source. Resistivities of the doped samples were measured with SDY-5 four-probe device at room temperature and photophobic condition. The samples were also analyzed using X-ray diferaction method. Experimental results show that resistivity and compensation degree of the doped samples both obtain maximum values when surface density of the daubed source is 23.4xlO"8 mol/cm2, while radial uniformity of resistivity of the sample is within 5%.
