[Object] To provide a composition capable of forming a cured film having low permittivity and excellence in chemical resistance, in heat resistance and in resolution; and further to provide a production process employing the composition. [Means] The present invention provides a composition comprising: an alkali-soluble resin, namely, a polymer comprising a carboxyl-containing polymerization unit and an alkoxysilyl-containing polymerization unit; a polysiloxane; a diazonaphthoquinone derivative a compound generating acid or base when exposed to heat or light; and a solvent.
