Patent ID: 7633085

Claim:
A semiconductor device comprising: an insulating substrate; at least one thin film transistor formed over the insulating substrate, the thin film transistor including at least a channel region, source and drain regions with the channel region therebetween, a gate insulating film adjacent to the channel region, and a gate electrode adjacent to the channel region with the gate insulating film interposed therebetween; a first conductive film formed over the thin film transistor and connected with one of the source region and drain region; a first inorganic insulating film covering said first conductive film; a second inorganic insulating film covering the first inorganic insulating film; an organic resin film covering the second inorganic insulating film; a contact hole that goes through the first inorganic insulating film, the second inorganic insulating film and the organic resin film; an inner side surface of the contact hole of the first and the second inorganic insulating films being a taper like having an angle range of 30 degree to 80 degree from a horizontal surface, the inner side surface being in contact with a bottom surface of the contact hole; and a second conductive film formed over the organic resin film and connected to said first conductive film at the bottom surface of the contact hole; wherein the second conductive film is a pixel electrode, and wherein a lower side end portion of the organic resin film in the contact hole is aligned with an upper side portion of the second inorganic insulating film in the contact hole.
