Abstract
A liquid material jetted from a nozzle is supplied onto a surface of the semiconductor substrate with use of an ink-jet mechanism comprising a liquid material receiving section, a driving section and a nozzle section. Since a film material (liquid material) is supplied by an ink-jet method, not only the film material only be supplied to a desired region of the semiconductor substrate surface and a supply to an unnecessary region is prevented, but also a variation of a film thickness comes not to be dependent on a pattern on the semiconductor substrate. Therefore, in forming a thin film on a semiconductor substrate, a thin film formation is realized so that utilization efficiency of a film material is increased with reduction in loss thereof and a variation of a thickness of the film formed is not influenced by a pattern on the semiconductor substrate.
