Publication number: 20100227469Abstract: A method of manufacturing a flash memory device. According to the invention, a floating gate can be formed and a distance between cells can be secured sufficiently by using one conductive layer without using a SA-STI process that cannot be applied to the manufacture process of high-integrated semiconductor devices. It is therefore possible to minimize an interference phenomenon between neighboring cells. Furthermore, an isolation film is etched after a photoresist film covering only a high-voltage transistor region is formed, or a gate oxide film is formed after a semiconductor substrate is etched at a thickness, which is the same as that of the gate oxide film of the high-voltage transistor region, so that a step between the cell region and the high-voltage transistor region is the same. Accordingly, the coupling ratio can be increased even by the gate oxide film of the high-voltage transistor region, which is thicker than the tunnel oxide film of the cell region.Type: ApplicationFiled: May 14, 2010Publication date: September 9, 2010Applicant: HYNIX SEMICONDUCTOR INC.Inventors: Joo Won Hwang, Byung Soo Park, Ga Hee Lee
