Abstract:
A method of fabricating a MEMS inkjet type print head and the resulting device is disclosed. The method includes providing a driver component and separately providing an actuatable membrane component, the actuatable membrane component being formed in the absence of an acid etch removing a sacrificial layer. The separately provided actuatable membrane component is bonded to the driver component and a nozzle plate is attached to the actuatable membrane component subsequent to the bonding. Separately fabricating the components removes the need for hydrofluoric acid etch removal of a sacrificial layer previously required for forming the actuatable membrane with respect to the driver component.
