  • Method for fabricating semiconductor memory
    Patent number: 6297084
    Abstract: A method for fabricating a semiconductor memory, in which a resistive layer is formed of a material identical to a material of a cell plug layer at a time of formation of the cell plug layer.
    Type: Grant
    Filed: August 26, 1999
    Date of Patent: October 2, 2001
    Assignee: Hyundai Electronics Industries Co., Ltd.

  • Method of fabricating semiconductor device
    Patent number: 6100164
    Abstract: A semiconductor device and a method of fabricating the same are disclosed. The method includes the steps of forming an anti-oxidation layer on a substrate, forming an oxidizable layer on portions of the anti-oxidation layer to expose a portion of the anti-oxidation layer, varying a size of the exposed portion of the anti-oxidation layer by oxidizing at least a portion of the oxidizable layer, and forming a trench in the substrate according to the size of the exposed portion of the anti-oxidation layer. The semiconductor device includes an anti-oxidation layer formed on a substrate an oxidation layer formed on portions of the anti-oxidation layer by oxidizing at least a portion of an oxidizable layer, so as to define an isolation region of the semiconductor device, a trench formed in the substrate using the oxidation layer, and a field oxide layer formed in the trench.
