Abstract:
1. A method of forming a plurality of capacitors, comprising: forming a plurality of individual capacitor electrodes comprising using two masking steps, an earlier of the two masking steps being used to form an array of first openings over a plurality of storage node contacts, a later of the two masking steps being used to form an array of second openings received partially over and partially offset from the array of first openings, overlapping portions of the first and second openings being received over the storage node contacts, individual of the first openings being no greater than 3.5F×5.5F in horizontal size, where “F” is the minimum feature size measured orthogonally; after both of the two masking steps, depositing conductive material of the individual capacitor electrodes into the overlapping portions of each of the first and second openings; and incorporating the individual capacitor electrodes into a plurality of capacitors.
