InactiveUS7029989B2Improve level of integrationHighly integratedTransistorSolid-state devicesImpurity diffusionSemiconductor
The present invention relates to a semiconductor device and a method of manufacturing the same. The minimum marginal width of an impurity diffusion layer is defined to reduce by a given width. The reduced width of the impurity diffusion layer is compensated for through a silicon growth layer formed on the top of a device isolation film having a relatively higher degree of freedom than the bottom of the device isolation film. Thus, the degree of integration in the semiconductor device can be improved while keeping intact the minimum marginal width of the impurity diffusion layer.
