Negative Photoresists: Tailored Solutions for Complex Designs

As the electronics and semiconductor industries continue to advance, the demand for high-resolution, precise, and reliable patterning techniques is greater than ever. At the heart of many of these advancements lies photoresist technology, specifically negative photoresists, which play a critical role in photolithography and microfabrication processes. These materials are essential in creating intricate circuit designs, microfluidic channels, and other complex microstructures. This article explores how negative photoresists are tailored to meet the demands of increasingly complex designs, their advantages, applications, and why they are vital for cutting-edge manufacturing in the UK’s high-tech industries. What Are Negative Photoresists? Photoresists are light-sensitive materials used to transfer patterns onto substrates during processes such as semiconductor manufacturing, MEMS fabrication, and printed circuit board (PCB) production. They are broadly categorised into two types: pos...
