  • Publication number: 20170243737
    Abstract: Disclosed is a method for manufacturing a semiconductor device, including a step of yielding a pattern 2a of a polysiloxane-containing composition over a substrate 1, and a step of forming an ion impurity region 6 in the substrate, wherein, after the step of forming an ion impurity region, the method further includes a step of firing the pattern at a temperature of 300 to 1,500° C. This method makes it possible that after the formation of the ion impurity region in the semiconductor substrate, the pattern 2a of the polysiloxane-containing composition is easily removed without leaving any residual. Thus, the yield in the production of a semiconductor device can be improved and the tact time can be shortened.

  • Publication number: 20120237873
    Abstract: Disclosed is a positive photosensitive resin composition which contains a polisiloxane, a naphthoquinone diazide compound, and a solvent. The positive photosensitive resin composition is characterized in that the polysiloxane has: an organosilane-derived structure represented by the general formula (1): at a content ration of 20-80% inclusive of Si relative to the overall number of moles of Si atoms in the polysiloxane; and an organosilane-derived structure represented by general formula (2): The positive photosensitive resin composition exhibits high heat resistance, high transparency, and enables high sensitivity, high resolution patterning. The positive photosensitive resin composition can be used to form cured films such as planarization films used in TFT substrates, interlayer insulating films, core materials and cladding materials, and can be used in elements having cured films such as display elements, semiconductor elements, solid-state imaging elements, and optical waveguide elements.
