Abstract: An improvement in the method of ion implantation into a semiconductor substrate through a photoresist mask wherein the photoresist mask is subjected to an RF gas plasma oxidation prior to the ion implantation step for a period sufficient to reduce the thickness of the photoresist layer. The ion implantation is then carried out through the treated photoresist mask.

Abstract translation: 通过光致抗蚀剂掩模将离子注入半导体衬底的方法的改进，其中在离子注入步骤之前对光致抗蚀剂掩模进行RF气体等离子体氧化一段足以减小光致抗蚀剂层厚度的时间。 然后通过经处理的光致抗蚀剂掩模进行离子注入。
