Abstract: PURPOSE:To lower capacity between electrodes and to stabilize the interface between a gate insulating film and a semiconductor thin film, by utilizing step covering property of the deposition of a conducting thin film on a stepped part having overhung parts, and automatically isolating the upper and lower parts of the stepped part. CONSTITUTION:On an insulating substrate 1, a semiconductor thin film 4, a gate insulating film 3 and a first conducting film 21 are sequentially deposited. Then, the first conducting film 21, the gate insulating film 3 and the semiconductor thin film 4 are made to remain as the approximately same island shape. The semiconductor thin film 4 is over-etched so that the edge parts of the film 4 are located at the inner part from the edge parts of the first conducting film 21 or the gate insulating film 3. Then, a second conducting film 9 is deposited on the entire surface. The thickness of the second conducting film 9 is less than that of the semiconductor thin film 4 and is constituted so that the film 9 is completely isolated by a stepped part. Then, the unnecessary part of the second conducting film 9 is selectively etched, and a source electrode 5 and a drain electrode 6 are formed. Thus the thin film transistor is completed.

Recording and reproduction of data by the recording light and reproducing light is enabled from the rear side of the substrate 2. The intermediate layer 4 contains at least one kind of compound among the metallic elements constituting the reflecting layer 5, and is substantially composed of the compound alone. Because of the presence of the intermediate layer 4, the reflecting layer 5 is not necessary to be formed only of Au and may be selected from metallic elements. An alloy corresponding to the required reflectance or color is used. Accordingly, the intermediate layer 4 eases the potential difference between the recording layer 3 and the reflecting layer 5, preventing a reaction between the coloring matter of the recording layer 3 and the reflecting layer 5, whereby the optical recording disc becomes inexpensive and highly reliable.
