    • An injection molding apparatus for injection molding a multi-layered article is disclosed. The apparatus comprises; (a) a mold having a cavity block provided with a cavity and a hot runner block, (b) at least a first injection cylinder and a second injection cylinder, (c) a first resin-flow-passage for connecting an inside of the first injection cylinder and the cavity, and (d) a second resin-flow-passage for connecting an inside of the second injection cylinder and the cavity. The injection molding apparatus has a structure in which those portions of the first and second resin-flow-passages which are located within the mold are provided in the hot runner block, and the first resin-flow-passage and the second resin-flow-passage meet with each other in a junction portion upstream to a gate portion opened to the cavity. The injection molding apparatus is provided with a back flow device for letting first molten resin in the first resin-flow-passage flow into the second resin-flow-passage after second molten resin is injected into the cavity through the second resin-flow-passage. The back flow device is operable in response to pressure which the first molten resin in the first resin-flow-passage exerts on second molten resin in the second resin-flow-passage.

    • A production method of a semiconductor element having a channel includes forming a resist pattern film on a thin film formed on a substrate, and pattering the thin film by etching. The production method also includes forming a second resist pattern film by applying a fluid resist material inside a channel groove after channel etching or inside a resist groove formed above a channel region before channel etching. The production method may also include forming a gate electrode, a gate insulating film, a semiconductor film, and a conductive film on an insulating substrate. The method may include applying the fluid resist material inside the channel groove, thereby forming the second resist pattern film, and patterning the semiconductor film using at least the second resist pattern film.
