摘要
介绍了以激光干涉法形成正弦调制起伏图形,结合电镀图形转移工艺获得了图形模板,采用旋转涂覆等工艺将调制图形转移至掺溴聚苯乙烯薄膜的表面,获得了掺溴聚苯乙烯平面调制箔靶。研究了调制起伏图形的精确转移工艺,以SEM和台阶仪监控图形转移过程,控制耦合在调制图形上的表面粗糙度。
Abstract
The preparation process of a surface perturbation target on a brominated polystyrene foil was introduced in this paper. Through a laser interference process and Nickel-electroplate figure-transfer process, a Ni-plate with sine modulated perturbation figure was obtained. Taking further steps to transfer the sine perturbation figure on the brominated polystyrene foil by spin-coating, doctor-blade casting and the thermal press process were studied. The transfer-precision of sine perturbation figures on the brominated polystyrene foil was measured by SEM and an α-step apparatus. The Bromine content in the brominated polystyrene was controlled. The surface roughness on the surface perturbation target of the brominated polystyrene foil was analysed.
