    摘要: A method of fabricating trench isolation for trench-capacitor DRAM devices. After the formation of deep trench capacitors, an isolation trench is etched into a substrate. The isolation trench is initially filled with a first insulating layer, which is then recessed into the isolation trench to a depth that is lower than the substrate main surface. An epitaxial layer is grown from the exposed sidewalls of the isolation trench. The isolation trench is then filled with a second insulating layer.

    摘要: Disclosed is a method for forming a shallow trench. The method of the present invention comprises steps of providing a substrate; forming a plurality of operation layers on the substrate; forming photoresist on the uppermost one of the operation layers to define a position to be etched; etching a portion of the operation layers at said position to form an opening; forming a spacing layer on the sidewall of the opening; and etching a portion of the substrate corresponding to the opening to form a shallow trench. By the etching method of the present invention, a striation phenomenon caused by the common mask etch is avoided.
