Abstract
Systems and methods for providing MEMS devices with integrated desiccant are provided. In one embodiment, a dry composition comprising desiccant is impact sprayed onto the backplate or substrate of a MEMS device, and becomes fused with the substrate. In another embodiment, the desiccant is impact sprayed such that the desiccant adheres to the impact sprayed surface. In yet another embodiment, the impact-sprayed surface is impregnated with the desiccant. In still another embodiment, the desiccant is combined with a suitable inorganic binder, then impact sprayed such that the desiccant adheres to the impact sprayed surface. In yet a further embodiment, the desiccant is micronized or pulverized into a powder of desired particle size, and then impact sprayed onto a surface. Thus, the desiccant particles or powder are fused onto the target surface through the impact spraying process.
