Patent ID: 7170178

Claim:
A capacitive structure produced in levels of an integrated circuit, said capacitive structure comprising: secondary stacks of superposed secondary electrodes arranged in at least two longitudinal rows and transversely facing one another, each of the secondary electrodes including transverse branches connected by a longitudinal branch such that the longitudinal branches are facing one another; third connection means for connecting the superposed secondary electrodes of each of the secondary stacks; first and second connection means for successively and alternately connecting the secondary stacks of one row to the secondary stacks of another row so as to constitute a first secondary group of secondary stacks that are connected together and a second secondary group of secondary stacks that are connected together, such that the secondary stacks of the first secondary group are located transversely facing the secondary stacks of the second secondary group and such that, in each row, the secondary stacks of the first secondary group and the secondary stacks of the second secondary group are arranged alternately; at least two principal stacks of superposed principal electrodes, each of the principal electrodes including transverse branches that are connected by a longitudinal branch, such that the longitudinal branches of the principal electrodes extend in front of and at a certain distance from the ends of the transverse branches of the rows of secondary electrodes, and such that the transverse branches of the principal electrodes and the transverse branches of the secondary electrodes of the rows extend opposite one another and between one another in an alternating fashion; fourth connection means for connecting the superposed principal electrodes of each of the principal stacks; fifth connection means for connecting the principal stacks so as to constitute a principal group of principal stacks of principal electrodes; and electrical connection branches, a first of the electrical connection branches being connected to the first secondary group of secondary stacks, a second of the electrical connection branches being connected to the second secondary group of secondary stacks, and a third of the electrical connection branches being connected to the principal group of principal stacks.
