Selective Bias Compensation for Patterning Steps in CMOS Processes

Abstract:

A method includes forming a photo resist pattern, and performing a light-exposure on a first portion of the photo resist pattern, wherein a second portion of the photo resist pattern is not exposed to light. A photo-acid reactive material is coated on the first portion and the second portion of the photo resist pattern. The photo-acid reactive material reacts with the photo resist pattern to form a film. Portions of the photo-acid reactive material that do not react with the photo resist pattern are then removed, and the film is left on the photo resist pattern.

Abstract(Chinese):

一种方法包括形成光致抗蚀剂图案，并对光致抗蚀剂图案的第一部分进行曝光，其中光致抗蚀剂图案的第二部分不暴露于光。在光致抗蚀剂图案的第一部分和第二部分上涂覆光酸反应性材料。光酸反应性材料与光致抗蚀剂图案反应形成膜。然后除去与光致抗蚀剂图案不反应的光酸反应性材料的部分，并且将膜留在光致抗蚀剂图案上。
