Abstract:
In a semiconductor device, capacitors may be formed so as to be in direct contact with a transistor by using a shared transistor region, such as a drain region or a source region of closely spaced transistors, as one capacitor electrode, while the other capacitor electrode is provided in the form of a buried electrode in the dielectric material of the contact level. To this end, dielectric material may be deposited so as to reliably form a void, wherein, at any appropriate manufacturing stage, a capacitor dielectric material may be provided so as to separate the capacitor electrodes.
