Patent abstract
An improved structure of a liquid drop emitter is provided which works to emit minute drops of liquid to deposit them in a dense array of dots on a substrate to produce a DNA chip, for example. The liquid drop emitter has a plurality of liquid inlets formed in rows in a staggered fashion, thereby allowing the liquid inlets to have a maximum possible area without any physical interference between adjacent two of them and also allowing outlet nozzles to be arranged in a dense array.
