Zusammenfassung: | This invention relates to improved semiconductor capacitors that are particularly useful for manufacturing improved dynamic random access memory (DRAM), among other semiconductor devices.
Described is a method of increasing the capacitance of semiconductor capacitors by providing a first solid-state electrode pattern on a semiconductor medium, etching topographic features on said first electrode pattern in a manner effective in increasing the surface area of said first electrode pattern, depositing a dielectric layer upon said electrode pattern that substantially conforms to said topographic features, and depositing a second solid-state electrode pattern upon said dielectric layer and sufficiently insulated from said first solid-state electrode pattern so as to create a capacitance with said first solid-state electrode pattern. |
