【摘要】 提出用激光诱导扩散法在室温电阻率大于15,000(Ω·cm)的P型高阻硅上制备低温欧姆接触(77—300K).研究了激光参数对低温比接触电阻值的影响关系,结合诱导区表面热学性质的理论计算讨论了实验结果.比较了二种不同的铟焊引线方法.

【Abstract】 The method to employ the laser-induced diffusion is developed to make the low tempera-ture ohmic contacts (77-300 K) on high resistivity P-type silicon (the room temperature resis-tivity greater than 15,000 Ohm-cm).The effect of laser parameters on the low temperaturespecific contact resistance of ohmic contacts is discussed in combination with the theoretic calcu-lation of the laser-induced regions.Two different welding ways are compared.
