Impact of wettability onto the growth of air bubbles at micro-cavities on silicon wafers: Experiments, simulations, and analytical solutions
The bubble growth at micro-cavities can be separated into a pinning stage and an expansion stage. On more hydrophobic surfaces, the duration of the pinning stage is shorter, and the bubble grows with a larger contact angle during the expansion stage, both contributing to faster bubble growth. A shape-dependent factor derived from simulations vividly describes the average mass flux into the bubble caps of given contact angles, providing a clear explanation of the impact of wettability on bubble growth.
