Understanding Resist Processing Equipment in Photolithography

Resist processing equipment is a vital component in the semiconductor fabrication process, specifically in photolithography, where intricate patterns are transferred onto silicon wafers. The process involves several key steps:

1. Coating – Applying a uniform layer of photoresist on the wafer.
2. Soft Baking – Pre-baking the resist to remove solvents and improve adhesion.
3. Exposure – Using a photomask and light source (e.g., deep ultraviolet or extreme ultraviolet) to define patterns.
4. Post-Exposure Bake (PEB) – Enhancing pattern fidelity and controlling chemical reactions.
5. Development – Removing unexposed or exposed photoresist, depending on the resist type (positive or negative).
6. Hard Baking – Strengthening the developed resist for subsequent etching or implantation.

Each of these steps demands high-precision equipment to ensure accurate patterning, which directly affects chip performance and yield.
