摘要: The present invention related to a method of fabricating a semiconductor device which prevents short channel hump due to the moisture in an insulating interlayer. The present invention includes the steps of forming a trench typed field oxide layer defining an active area in a field area of a semiconductor substrate of a first conductive type, forming a gate to the direction of device width wherein a gate oxide layer is inserted between the gate and semiconductor substrate, forming impurity regions in the semiconductor substrate at both sides of the gate by ion implantation with impurities of a second conductive type, forming an insulating interlayer covering the gate on the semiconductor substrate, and removing moisture contained in the insulating interlayer by thermal treatment.

摘要: A semiconductor device isolation structure and a fabricating method therefor are disclosed. The isolation structure includes a trench which is formed on an isolating region to define an active region. First, second, and third insulating layers are deposited in the trench. The second insulating layer has an etch selection ratio different from those of the first and third insulating layers. The edge portions of the third insulating layer which contact the side walls of the trench characteristically do not show any collapse. Therefore, when supplying a subthreshold voltage, a hump phenomenon does not occur. As a result, leakage current is kept from increasing, and the device refresh characteristic can be kept from deteriorating. Further, the third insulating layer covers the top edge portions of the trench. Therefore, the gate insulating layer (which is formed later) has a sufficient thickness. Therefore, yield voltage characteristics can be kept from deteriorating.
