We analyze the wetting behavior of a solid adsorbate island on a substrate with parallel grooves. The island is found in three main states, with different shapes and positions: a lifted Cassie-Baxter–like state, a collapsed Wenzel-like state, and a capillary filling state. The stability of these states is summarized in a two-loop–hysteresis diagram. Quantitative agreement is found between kinetic Monte Carlo simulations and a simple analytical model.
