Provided is a nozzle arrangement for an inkjet printhead. The arrangement includes a substrate defining an ink inlet channel and ink chamber with a CMOS layer deposited on top of the substrate, and a nozzle wall, roof and rim positioned on top of the substrate via which ink is operatively ejected from the chamber. The arrangement also includes an anchor atop the CMOS layer, said anchor linked to a stiffening beam by means of an actuator beam, the stiffening beam suspended from the CMOS layer by means of a passive beam and a carrier. Further included is a diffusion barrier about the ink chamber to inhibit the diffusion of hydroxyl ions through the CMOS layer.
