METHODS OF MAKING AN INKJET PRINT HEAD BY SAWING DISCONTINUOUS SLOTTED RECESSES

摘要

A method of making an inkjet print head may include forming, by sawing with a rotary saw blade, first discontinuous slotted recesses in a first surface of a wafer. The first discontinuous slotted recesses may be arranged in parallel, spaced apart relation. The method may further include forming, by sawing with the rotary saw blade, second discontinuous slotted recesses in a second surface of the wafer aligned and coupled in communication with the first continuous slotted recesses to define through-wafer channels. In another embodiment, the first and second plurality of discontinuous recesses may be formed by respective first and second rotary saw blades.
