  • Method for manufacturing semiconductor device by forming insulator-layer to suppress bubble formation
    Patent number: 5444026
    Abstract: The present invention forms a intermediate layer between a conductive layer and BPSG layer. In one embodiment, this intermediate layer is a buffer layer that absorbs excess P ions from the BPSG layer to suppress the formation of bubbles and thereby prevent short circuits that may be caused due to the presence of bubbles in the BPSG layer. In the second embodiment the intermediate layer is a thin nitride layer, which prevents the conductive layer and BPSG layer from being in direct contact with each other to suppress the formation of bubbles and also prevent short circuits that may be caused due to the presence of bubbles in the BPSG layer.
