A method of producing an ink jet printhead is provided so that the printhead has a structure with a plurality of nozzles, each having a nozzle opening through a single surface layer of the structure, with the areal density of the nozzles being greater than 10 nozzles per square centimeter of the surface layer. In the method, the structure is formed in-situ on an underlying substrate so that the surface layer has a thickness of ten microns or less and so that each nozzle opening is defined as a hole through the surface layer. The substrate has at least one heater element corresponding to each of the nozzles respectively. The heater elements thermally contact a bubble forming liquid to heat at least part of it above its boiling point thereby forming a gas bubble to eject a drop of the liquid through the nozzle openings in a predetermined direction.
