Abstract
An inkjet printhead includes a substrate having an ink feed slot formed therein. The inkjet printhead includes drop generators and ink feed channels. Each drop generator has a nozzle and a vaporization chamber. At least one ink feed channel is fluidically coupled to each vaporization chamber and is fluidically coupled to the ink feed slot. A thin-film structure is supported by the substrate and defines a first portion of each ink feed channel. An orifice layer supported by the substrate defines the nozzles and the vaporization chambers in the drop generators. The orifice layer defines a second portion of each ink feed channel.
