Abstract: The present invention relates to metal-insulator-metal (MIM) capacitors and field effect transistors (FETs) formed on a semiconductor substrate. The FETs are formed in Front End of Line (FEOL) levels below the MIM capacitors which are formed in upper Back End of Line (BEOL) levels. An insulator layer is selectively formed to encapsulate at least a top plate of the MIM capacitor to protect the MIM capacitor from damage due to process steps such as, for example, reactive ion etching. By selective formation of the insulator layer on the MIM capacitor, openings in the inter-level dielectric layers are provided so that hydrogen and/or deuterium diffusion to the FETs can occur.

Abstract: A patterned mask can be formed as follows. A first patterned photoresist is formed over a masking layer and utilized during a first etch into the masking layer. The first etch extends to a depth in the masking layer that is less than entirely through the masking layer. A second patterned photoresist is subsequently formed over the masking layer and utilized during a second etch into the masking layer. The combined first and second etches form openings extending entirely through the masking layer and thus form the masking layer into the patterned mask. The patterned mask can be utilized to form a pattern in a substrate underlying the mask. The pattern formed in the substrate can correspond to an array of capacitor container openings. Capacitor structure can be formed within the openings. The capacitor structures can be incorporated within a DRAM array.
