Abstract
Methods of forming integrated circuit devices include forming first and second gate electrodes at side-by-side locations on a substrate and forming first and second sidewall spacers on sidewalls of the first gate electrode and the second gate electrode, respectively. The first and second gate electrodes are covered with a first electrically insulating layer of a first material. A second electrically insulating layer of a second material is deposited on the first electrically insulating layer. The second electrically insulating layer is patterned to define a first opening therein that exposes an underlying first portion of the first electrically insulating layer.
