Abstract
A method of producing a thin film transistor comprises the steps of preparing a structure having a substrate, an active layer and a diffusion layer formed on the substrate, and a gate electrode formed on the active layer, forming on the structure an interlayer insulator layer made of a silicon oxide hydrate (SiO.sub.x H.sub.y) having a predetermined composition, forming contact holes in the interlayer insulator layer, forming a wiring layer on the interlayer insulator layer, and carrying out a thermal process thereby diffusing hydrogen atoms within the interlayer insulator layer into at least the active layer and the diffusion layer.
