Abstract

Microelectronics manufacturing of modern devices has required the use of polymer photoresists in several essential steps. The traditional limitation in device capability has been dependent on the minimum feature size attainable by the wavelength of light and materials used in photolithography. In this thesis the study of polymer thin films in single and bilayer stacks is described. Three scientific concepts are fundamental to this study: (1) the diffusion and (2) reaction of acid and small molecules that change polymer (3) solubility. In this thesis, two chemical systems are designed and used to study these three scientific concepts.
