Methods of manufacturing a semiconductor integrated circuit using selective disposable spacer technology and semiconductor integrated circuits manufactured thereby: The method includes forming a plurality of gate patterns on a semiconductor substrate. Gap regions between the gate patterns include first spaces having a first width and second spaces having a second width greater than the first width. Spacers are formed on sidewalls of the second spaces, and spacer layer patterns filling the first spaces are also formed together with the spacers. The spacers are selectively removed to expose the sidewalls of the first spaces. As a result, the semiconductor integrated circuit includes wide spaces enlarged by the removal of the spacers and narrow and deep spaces filled with the spacer layer patterns.

Semiconductor integrated circuit using a selective disposable spacer

Disclosed is a method for fabricating a NOR flash memory device where a buried common source line made of an impurity diffusion layer has an even surface or a lower step difference. The method includes forming adjacent isolation layers that define an active region there between within a semiconductor substrate. Then, a floating gate pattern is formed overlying the active region. An inter-gate dielectric film and a control gate film are sequentially formed overlying the floating gate pattern. The control gate film, the inter-gate dielectric film, and the floating gate pattern are sequentially patterned, thereby forming a plurality of word lines extending across the active region. The active region between the adjacent isolation layers and the isolation layers are removed, adjacent to one sidewall of the word lines, thereby forming a common source line region. Next, impurities are implanted into the common source line region, thereby forming a common source line made of an impurity diffusion layer.
