This application discloses a spin-coating carbon composition, a semiconductor fabrication method, and a semiconductor device. The spin-coating carbon composition comprises a cyclic phenolic resin. The cyclic phenolic resin used in this invention has the characteristics of small molecular weight, narrow molecular weight distribution, and active crosslinking groups distributed on the resin periphery. The spin-coating carbon composition based on the cyclic phenolic resin of this invention, while maintaining excellent coating performance, can significantly improve the thermal stability, etching resistance, and pattern fidelity of the thin film, providing a new generation of hard mask materials for advanced semiconductor manufacturing.

The application provides a plugging-preventing fluid for resin cementing fluid and a preparation method and use method thereof. The plugging-preventing fluid comprises the following components in parts by weight: water 100 parts, epoxy resin diluent 15-100 parts, emulsifier 5-15 parts, and suspension stabilizer 0-3 parts. The epoxy resin diluent has good compatibility with the epoxy resin, which can delay the curing time of the epoxy resin. The emulsifier can effectively reduce the interfacial tension of each component of the mixed system of the epoxy resin and the water phase of the plugging-preventing fluid, and form a relatively strong film on the surface of the epoxy resin droplets or a double electric layer on the surface of the epoxy resin droplets, so as to prevent the droplets from gathering with each other, and keep the uniform emulsion to prevent the epoxy resin from gathering and curing to leave a plug. The suspension stabilizer can make the plugging-preventing fluid better suspend the resin droplets, prevent the suspended resin droplets from settling and gathering, and hinder the epoxy resin from gathering and curing.
