3D microfabrication

3D microfabrication is a collection of techniques used to create three-dimensional structures at the microscale, typically in the range of micrometers to millimeters. This technology plays a crucial role in various fields, including electronics, biotechnology, materials science, and engineering. The process often involves: 1. **Photolithography**: Utilizing light to transfer patterns onto a substrate coated with a photosensitive material.
