Methods of forming a three-dimensional capacitor network may include forming a first horizontal MIM capacitor on a semiconductor substrate and forming a first interlayer insulating layer on the first horizontal MIM capacitor. A first vertical capacitor electrode is then formed in the first interlayer insulating layer and a second horizontal MIM capacitor is formed on the first interlayer insulating layer. This second horizontal MIM capacitor may be formed by forming an upper capacitor electrode and a lower capacitor electrode. The upper capacitor electrode may be electrically connected by the first vertical capacitor electrode to an upper capacitor electrode of the underlying first MIM capacitor. The lower capacitor electrode, which may be formed in the first interlayer insulating layer, may extend opposite the upper electrodes of the first and second MIM capacitors.
摘要:
An oxide layer is used to seal pores in porous low-dielectric constant materials, thus preventing the migration of subsequently deposited copper materials into the porous low-dielectric constant materials in damascene processes. The oxide layer is deposited over the inner surface of at least one pore along a sidewall of the patterned low-dielectric constant material. In one embodiment, the oxide layer is deposited using atomic layer deposition (ALD), and the oxide layer comprises SiO2.
