摘要： The invention is directed to an integrated circuit comb capacitor with capacitor electrodes that have an increased capacitance between neighboring capacitor electrodes as compared with other interconnects and via contacts formed in the same metal wiring level and at the same pitches. The invention achieves a capacitor that minimizes capacitance tolerance and preserves symmetry in parasitic electrode-substrate capacitive coupling, without adversely affecting other interconnects and via contacts formed in the same wiring level, through the use of, at most, one additional noncritical, photomask.

摘要： Methods of fabricating a passive element and a semiconductor device including the passive element are disclosed including the use of a dummy passive element. A dummy passive element is a passive element or wire which is added to the chip layout to aid in planarization but is not used in the active circuit. One embodiment of the method includes forming the passive element and a dummy passive element adjacent to the passive element; forming a dielectric layer over the passive element and the dummy passive element, wherein the dielectric layer is substantially planar between the passive element and the dummy passive element; and forming in the dielectric layer an interconnect to the passive element through the dielectric layer and a dummy interconnect portion overlapping at least a portion of the dummy passive element. The methods eliminate the need for planarizing.

摘要： A method is provided for fabricating a microelectronic chip which includes a passive device such, as an inductor, overlying an air gap. In such method, a plurality of front-end-of-line (“FEOL”) devices are formed in a semiconductor region of the microelectronic chip, and a plurality of stacked interlevel dielectric (“ILD”) layers are formed to overlie the plurality of FEOL devices, the plurality of stacked ILD layers including a first ILD layer and a second ILD layer, where the second ILD layer is resistant to attack by a first etchant which attacks the first ILD layer. A passive device is formed to overlie at least the first ILD layer. Using the first etchant, a portion of the first ILD layer in registration with the passive device is removed to form an air gap which underlies the passive device in registration with the passive device.
