Zusammenfassung:	A method of manufacturing a printhead includes providing a substrate and a filter membrane structure. A first portion of the substrate defines a plurality of nozzles and a second portion of the substrate defines a plurality of liquid chambers. Each liquid chamber of the plurality of liquid chambers is in fluid communication with a respective one of the plurality of nozzles. The filter membrane structure is adhered, for example, laminated, to the second portion of the substrate. Each liquid chamber of the plurality of liquid chambers is in fluid communication with a distinct portion of the filter membrane structure. Pores are formed in the filter membrane structure using a photo-lithography process.
