Methods for protecting the bottom of trenches using photoresist partial filling process in wet etching

This invention discloses a method for protecting the bottom of trenches in wet etching using a photoresist partial filling process. The method includes: fabricating a trench structure on a predetermined area of ​​the wafer surface using plasma etching; applying photoresist to the entire trench structure and the entire wafer surface using spin coating; performing exposure and development on the entire surface of the wafer covered with photoresist using a photolithography machine without a photomask, thereby removing some of the photoresist on the upper surface of the wafer oxide layer and in the upper region of the trench structure, leaving the remaining photoresist in the trench area in a partially filled state; and removing the exposed oxide layer on the wafer surface, thus protecting the bottom of the trench from damage using the remaining photoresist in the trench area. This invention is applicable to both plasma etching and wet etching, effectively reducing the difficulty, cost, and time of etching processes, achieving low cost and a simple process. It is a novel method for eliminating damage to the bottom of deep trenches by using photoresist filling in deep trenches, suitable for wet etching.
