Abstract: PURPOSE: A method for manufacturing a dual gate oxidation layer of a semiconductor device is provided to simplify a manufacturing process, by eliminating the need to control etching quantity of an oxidation layer, and by securing a uniform thickness. CONSTITUTION: An oxidation layer and a nitride layer are sequentially formed on the entire surface of a semiconductor substrate(21) having a gate insulating layer formation region with the first and second thickness. The surface of the nitride layer is thermally oxidized to form a thin nitride/oxidation layer. A photoresist pattern layer remaining only in the gate insulating layer formation region with the second thickness is formed. The exposed nitride/oxidation layer of the first thickness and the nitride layer are removed by using the photoresist pattern layer as a mask. The photoresist pattern layer is eliminated, and the oxidation layer in the gate insulating layer formation region with the first thickness is removed. An oxidation layer is formed on the substrate by using as a mask the nitride layer in the gate insulating layer formation region with the second thickness, to form a gate insulating layer(26) with the first thickness. A second gate insulating layer(27) with the second thickness consisting of a stack structure of an oxidation layer and a nitride layer is formed in the gate insulating layer formation region with the second thickness.
