Abstract
A method of forming an inkjet printhead. The method includes the steps of: providing a metal alloy shim having a plurality of shim apertures; nitriding a surface of the shim; bonding the shim to a rigid elongate manifold having ink supply channels, such that each shim aperture is in fluid communication with a respective ink supply channel; and bonding printhead chips to the shim, thereby forming the inkjet printhead.
