  • Patent number: 10756164
    Abstract: A system and method for fabricating metal insulator metal capacitors while managing semiconductor processing yield and increasing capacitance per area are described. A semiconductor device fabrication process places an oxide layer on top of a metal layer. A photoresist layer is formed on top of the oxide layer and etched with repeating spacing. One of a variety of lithography techniques is used to alter the distance between the spacings. The process etches trenches into areas of the oxide layer unprotected by the photoresist layer and strips the photoresist layer. The top and bottom corners of the trenches are rounded. The process deposits a bottom metal, a dielectric, and a top metal on the oxide layer both on areas with the trenches and on areas without the trenches. The process completes the metal insulator metal capacitor with metal nodes contacting each of the top plate and the bottom plate.

Pressure that builds up under the lid from gas escaping from the liquid may be relieved by outgassing through the passageway. The cover includes latches on the base that engage in notches on the lid to help lock the lid in place. The lid is rotated relative to the base to release the latches and permit the lid to be opened.
