Latest Patents

Förster's latest patents include a method for fabricating a trench capacitor for a semiconductor memory. This innovative method involves forming a masking layer in a trench disposed in a substrate. Nanocrystallites are deposited on the masking layer to pattern it. Microtrenches are then etched into the substrate in the lower region of the trench by the patterned masking layer, resulting in a roughened trench sidewall. This design allows the outer capacitor electrode to have a larger surface area, thereby increasing the capacitance of the trench capacitor. Another patent focuses on a method for fabricating a trench capacitor, which includes providing a silicon substrate and forming a trench with a lower region and surface. A doped layer is formed in the silicon substrate in the lower region of the trench, and a roughened silicon layer with grains ranging from 10 to 100 nm is produced. A dielectric intermediate layer is applied on this roughened silicon layer, and the trench is filled with a doped layer.
