Abstract:
1. A method for manufacturing a semiconductor device comprising: forming a base film over an insulating substrate; forming a thin film transistor over the base film, wherein the thin film transistor includes a semiconductor layer, a gate insulating film and a gate electrode; forming a first interlayer insulating film over the gate insulating film and the gate electrode; forming a first contact hole in the first interlayer insulating film; forming a wiring over the first interlayer insulating film, wherein the wiring is electrically connected to the semiconductor layer through the first contact hole; forming a resin containing siloxane polymer over the first interlayer insulating film and the wiring; heating the resin in an atmosphere containing an inert gas to form a second interlayer insulating film, wherein the atmosphere has an oxygen concentration of 5% or less and a water concentration of 1% or less; forming a second contact hole in the second interlayer insulating film; and forming an electrode over the second interlayer insulating film, wherein the electrode is electrically connected to the wiring through the second contact hole.
