发明名称 Herstellungsverfahren in Spacer-Technik für einen Festwertspeichertransistor mit Auswahlgate an einer Seite eines Kontrollgate-Floating-Gate-Stapels
摘要 Consistent with an example embodiment, there is a method for manufacturing a semiconductor device. The semiconductor device comprises a semiconductor body provided at a surface with a non-volatile memory including a memory cell with a gate structure with an access gate and a gate structure with a control gate and a charge storage region situated between the control gate and the semiconductor body. In the method, on the surface of the semiconductor body a first one of said gate structures is formed with side walls extending substantially perpendicular to the surface, a conductive layer is deposited on and next to said first gate-structure, the conductive layer is subjected to a planarizing treatment until the first gate structure is exposed and the so planarized conductive layer is patterned so as to form at least a part of the other gate structure adjoining only a first one of the side walls of the first gate structure.
