Abstract: There is disclosed a structure for radiating heat generated by TFTs in a liquid crystal panel. A DLC film 125 is provided on a resin interlayer film 123 disposed on the TFTs 105, 109, and 113. The DLC film 125 can be easily formed on the resin film, and has high heat conductivity, so that the film can be made to function as a heat radiating layer.

Abstract: A process reduced in mask steps for use in the fabrication of a thin film transistor having an LDD structure, comprising anodically oxidizing a gate electrode of a thin film transistor and performing ion implantation using the thus formed anodic oxide film as the mask. Also claimed is a similar process for fabricating a p-channel transistor and an n-channel transistor on a single substrate, comprising performing ion implantation of an impurity of the first conductive type to both of the transistor regions by using the anodic oxide film as a mask, and then performing ion implantation of an impurity of the second conductive type while masking one of the transistor regions with a resist.
