Abstract
A semiconductor device includes a substrate including a memory cell region and a peripheral region and a field pattern including an insulating region disposed on a nitride liner in a trench in the substrate adjacent an active region. The field pattern and the active region extend in parallel through the cell and peripheral regions. The device also includes a transistor in the peripheral region including a source/drain region in the active region. The device further includes an insertion pattern including an elongate conductive region disposed in the substrate and extending along a boundary between the field pattern and the active region in the peripheral region. Fabrication methods are also described.
