The microelectronic market imposes tight requirements upon thin film properties, such as surface roughness and film thickness. Thin film deposition is a batch process where the microscopic events determine the configuration of the thin film surface. However, manipulating the process at the macroscopic level is essential to the product quality. There are three major obstacles for developing efficient control methodologies for thin film deposition in the semiconductor industry: i) development of fundamental mathematical models describing the multiscale nature of this process, ii) lack of practical in-situ sensors that provide real-time measurements for online control, and iii) uncertainties in the microscale mechanisms and parameters of the system. The main goal of my research is to address these challenges for robust control and optimization purposes in the multiscale thin film deposition process. The respective publications of this project is available in  here.
