Moisture protection of fluid ejector

A fluid ejector, comprising:

• a fluid ejection module comprising a substrate having a plurality of fluid paths and a plurality of actuators, each actuator configured to cause a fluid to be ejected from a nozzle of an associated fluid path;
• a plurality of integrated circuit elements, wherein the integrated circuit elements are microchips other than the substrate, wherein the plurality of integrated circuit elements are mounted on the substrate of the fluid ejection module and positioned above the plurality of actuators, and wherein the plurality of integrated circuit elements comprises transistors;
• and
• a housing positioned to form a cavity above the fluid ejection module, the housing having a channel, wherein the channel connects the cavity with a chamber, the chamber comprising an absorbent material.
