    Abstract: Methods and apparatus for oxygen radical annealing or plasma annealing various layers (e.g., a lower electrode, a dielectric layer, or an upper electrode) of a microelectronic capacitor on a substrate are provided. By oxygen radical or plasma annealing the lower electrode of the capacitor, the leakage current characteristic of the capacitor may be improved such that the leakage current is reduced, for example, by a factor of 100 or more. The amount of impurities on the lower electrode may also be reduced. Oxygen radical or plasma annealing the dielectric layer of the capacitor may improve the leakage current characteristics of the capacitor and may reduce the amount of impurities in the dielectric layer.

  • Publication number: 20020163026
    Abstract: A capacitor in which a generation of a bad storage node can be reduced and a method of manufacturing the same. An opening is formed at a portion of an insulating layer on a semiconductor substrate for exposing a conductive structure under the insulating layer. A polysilicon film is formed on a top surface of the insulating layer and a sidewall and a bottom surface of the opening. A supporting film is formed on the polysilicon film. The polysilicon film and the supporting film are partially etched so that the polysilicon film and the supporting film remain only on the sidewall and the bottom surface of the opening, thereby forming a storage electrode. A dielectric film and a plate electrode are formed on the storage electrode. The generation of a bad capacitor can be reduced by using the supporting film to keep the node of the storage electrode from being inclined.

  • Publication number: 20010007366
    Abstract: A ferroelectric random access memory (FRAM) device, and a fabrication method therefor, includes seed layers above and below a ferroelectric layer. The seed layers formed above and below faces of the ferroelectric layer can prevent an imprint phenomenon from being generated in a ferroelectric capacitor by making the characteristics of the upper and lower interfaces of the ferroelectric layer be the same. This is accomplished by providing upper and lower seed layers that are crystallized prior to the ferroelectric layer during a thermal treatment. This results in crystallization occurring from the upper and lower faces to the center of the ferroelectric layer, making the characteristics of the upper and lower interfaces of the ferroelectric layer the same, thereby improving ferroelectric capacitor characteristics.

  • Patent number: 6218229
    Abstract: The method of fabricating a semiconductor device having a dual-gate provides a semiconductor substrate with a gate insulating film formed on a first portion and a second portion thereof and a polysilicon layer formed on the gate insulating film. A first dopant of a first conductive type is implanted in the polysilicon layer covering the first portion, and a second dopant of a second conductive type is implanted in the polysilicon layer covering the second portion. Then, the polysilicon layer covering the first portion is selectively etched using a first mask to form a first gate, and a third dopant of the first conductive type is implanted to form source/drain LDD regions on both sides of the first gate. Thereafter, the polysilicon layer covering the second portion is selectively etched using a second mask to form a second gate, and a fourth dopant of the second conductive type is implanted to form source/drain LDD regions on both sides of the second gate.

  • Patent number: 6146935
    Abstract: A method for forming a capacitor of a semiconductor device. A lower electrode is prebaked before a dielectric layer is formed on the lower electrode. As a result, moisture or contaminants are removed from the lower electrode, increasing adhesion between the lower electrode and the dielectric layer formed on the lower electrode, thereby preventing the dielectric layer from being lifted and cracked due to inferior coating properties.
