  • Patent number: 4686000
    Abstract: An improved process for self-aligned contact window formation in an integrated circuit leaves a "Stick" of etch stop on vertical sidewall surfaces to be protected. The technique includes, in the preferred embodiment, a layer of oxide over active areas and on top of the gate electrode of a transistor. The oxide is thicker on top of the gate electrode than over the active area. A silicon nitride layer acting as an etch stop is included between the oxide and interlevel dielectric such as BPSG. Contact windows may deviate from their intended position and partially overlie a poly edge such as a gate electrode or an isolation (field-shield) or field oxide edge. Two-step etching comprises first etching the BPSG down to the etch stop layer, then etching the etch stop and underlying oxide, leaving a "stick" of etch stop on the side of the layer to be protected.
