Abstract: The present disclosure is directed to a microfluidic die that includes ejection circuitry and one time programmable memory with a minimal number of contact pads to external devices. The die includes a relatively large number of nozzles and a relatively small number of contact pads. The die includes decoding circuitry that utilizes the small number of contact pads to control the drive and ejection of the nozzles and the reading/writing of the memory with the same contact pads.

Abstract: Embodiments are directed to microfluidic refill cartridges and methods of assembling same. The microfluidic refill cartridges include a microfluidic delivery member that includes a filter for filtering fluid passed therethrough. The filter may be configured to block particles above a threshold size to prevent blockage in the nozzles. For instance, particles having a dimension that is larger than the diameter of the nozzles can block or reduce fluid flow through the nozzle.

Abstract: An ink jet printhead device includes a substrate and at least one first dielectric layer above the substrate. A resistive layer is above the at least one first dielectric layer. An electrode layer is above the resistive layer and defines first and second electrodes coupled to the resistive layer. At least one second dielectric layer is above the electrode layer and contacts the resistive layer through the at least one opening. The at least one second dielectric layer has a compressive stress magnitude of at least 340 MPa.
