Photoresist coating
This process uniformly coats a wafer surface with a photosensitive agent called photoresist.
Photoresist coating is a pivotal step in semiconductor manufacturing, specifically within the photolithography process. In this process, a semiconductor wafer undergoes spinner coating, where liquid photoresist is evenly spread across its surface through rapid spinning. Following this, a soft bake removes solvents and enhances adhesion. The success of semiconductor fabrication heavily relies on the precision and uniformity achieved during photoresist coating. The choice between positive and negative photoresists, as well as the careful execution of soft and hard bake steps, plays a crucial role in determining the effectiveness of subsequent processes.
