Abstract: PURPOSE: A method for forming a CMOS transistor is provided to simplify process and reduce costs by removing an etching process for forming a spacer. CONSTITUTION: The method forms a CMOS transistor to a peripheral area of a semiconductor substrate(100) on which a P-well and a N-well are formed. The first step of the method is to form a gate oxide film(140) on a semiconductor substrate in which each well is formed. The second step is to form gate patterns for a PMOS and a NMOS on the upper of the N- and P-wells respectively. The third step is to form an insulating film for a conformal spacer on each of the gate patterns and the gate oxide film. The fourth step is to form a conductive film for forming a cell pad on the insulating film for the spacer. The fifth step is to remove the conductive film for forming the cell pad using an anisotropic etch and simultaneously leave the conductive film to thickness less than about 200Å by etching a part of the conductive film for the spacer on the gate insulating film(240b). The sixth step is to complete PMOS and NMOS transistors by implanting ions on the insulating film for the spacer remaining on the gate insulating film using the insulating film for the spacer formed on the each gate pattern, side wall thereof and upper thereof as a mask.
