Tuning Photoresist Adhesion with HMDS: Deep Dive into Photolithography

In the fields of semiconductor manufacturing and microfabrication, photolithography is an essential technique that creates intricate patterns on substrate surfaces. The patterning process is used frequently in electronics, microfluidics, and sensors and creates a protective layer from additional manufacturing processes and mechanical wear during its final application. To create these patterns, a mask and photoresist are applied to the substrate and exposed to light. After exposure, the photoresist is developed using a chemical solution, and the unexposed sections of the photoresist are dissolved, resulting in the desired pattern.

How HMDS is Used in Surface Science

Hexamethyldisilazane (HMDS) is a colorless, flammable liquid with a unique chemical structure. It is frequently used in surface science as a primer agent to treat the surfaces of silicon wafers and make them more suitable for adhesion with a photoresist. Using HMDS is also common as a pre- and post-treatment method for surface coating applications. In this blog post, we will look at how HMDS is used in surface science and the benefits of doing so.
