摘要
本文采用各向异性腐蚀和干-湿-干氧化锐化工艺,在n型,(100)晶向、电阻率为3~5Ωcm、3英寸硅片上均匀制备了三种结构硅尖阵列场致发射二极管。锥尖密度达15000个/mm ̄2,硅尖曲率半径小于30nm;在35V收集极电压下,单尖发出电流达0.14μA,其Ⅰ—Ⅴ曲线与F—N公式类似。
Three types of diodes of silicon field emission arrays have been succssfuly fabricated on the Si (100)substrate(n type.ρ=3~5Ω·cm)The density of tips is up 15000tips/mm ̄2,and the radii of tips are less than 30nm,At 35V on the anode ,Currents averaging to o.14μA/tip have been measured,The Characteristion of I-V curves are simillar to the F-Nformula.
