Photoresist ancillaries refer to a range of chemicals and materials used in conjunction with photoresists during the lithography process in semiconductor manufacturing. These ancillaries play crucial roles in enhancing the performance and efficiency of the lithographic techniques employed to create intricate patterns on substrates.

Types of Photoresist Ancillaries

1. Developers:

Developers are used to create patterns by exploiting the differences in solubility between exposed and unexposed areas of the photoresist. This process is essential for transferring the desired patterns onto the substrate.
