Developer Configurations
The use of immersion tank processes in photolithography has decreased due to excessive material consumption, non-uniform resolution, and poor clearing from high-aspect-ratio features. Spin developing has become the more popular method for development of features in photolithography, with three main methods emerging: puddle/stream dispense, side spray dispense, and direct spray dispense. The side spray dispense […]
Multi-Stage Baking with Programmable Lift Pins
Smart-Pin technology enables flexible temperature ramping and uniform baking for thermal shock sensitive materials. The lift pin height recipe utilizes a temperature matrix for soft bake, PEB, and post-develop hard bake. The programmable system eliminates the need for multiple bake plates and is suitable for thick-film materials and mitigating the “skin” effect. Multi-Stage Baking with […]
