  • Patent number: 9360755
    Abstract: Among other things, one or more techniques and systems for performing a spin coating process associated with a wafer and for controlling thickness of a photoresist during the spin coating process are provided. In particular, a thickening phase is performed during the spin coating process in order to increase a thickness of the photoresist. For example, air temperature of down flow air, flow speed of the down flow air, and heat temperature of heat supplied towards the wafer are increased during the thickening phase. The increase in down flow air and heat increase a vaporization factor of the photoresist, which results in an increase in viscosity and thickness of the photoresist. In this way, the wafer can be rotated at relatively lower speeds, while still attaining a desired thickness. Lowering rotational speed of wafers allows for relatively larger wafers to be stably rotated.
