摘要:
A novel method for forming electrodes in the fabrication of an MIM (metal-insulator-metal) capacitor, is disclosed. The method improves MIM capacitor performance by preventing plasma-induced damage to a dielectric layer during deposition of a top electrode on the dielectric layer, as well as by reducing or preventing the formation of an interfacial layer between the dielectric layer and the electrode or electrodes, in fabrication of the MIM capacitor. The method typically includes the patterning of crown-type capacitor openings in a substrate; depositing a bottom electrode in each of the crown openings; subjecting the bottom electrode to a rapid thermal processing (RTP) or furnace anneal step; depositing a dielectric layer on the annealed bottom electrode; depositing a top electrode on the dielectric layer using a plasma-free CVD (chemical vapor deposition) or ALD (atomic layer deposition) process; and patterning the top electrode of each MIM capacitor.

A system and method for manufacturing a semiconductor device is provided. An embodiment comprises forming a deposited layer using an atomic layer deposition (ALD) process. The ALD process may utilize a first precursor for a first time period, a first purge for a second time period longer than the first time period, a second precursor for a third time period longer than the first time period, and a second purge for a fourth time period longer than the third time period.
摘要:
A method is described for progressively forming a fuse access openings in integrated circuits which are built with redundancy and use laser trimming to remove and insert circuit sections. The fuses are formed in a polysilicon layer and covered by one or more relatively thin insulative layers. An etch stop is patterned over the fuse in a higher level polysilicon layer or a first metallization layer. Additional insulative layers such as inter-metal dielectric layers are then formed over the etch stop. A first portion of the laser access window is then etched during the via etch for the top metallization level. The etch stop prevents removal of the insulation subjacent to it. Cumulative thickness non-uniformities in the relatively thick upper insulative layers are thus removed from the fuse window. The etch stop is removed during patterning of the top level metallization. A passivation layer is applied and patterned to exposed bonding pads and, at the same time complete the etching of the laser access window to a desired thickness over the fuses. The passivation layer over etch required to penetrate the insulation layer over the fuses also removes an ARC over the bonding pads. The process fit conveniently within the framework of an existing process and does not introduce any additional steps. In addition, the passivation layer can be patterned to form final access to both bonding pads and laser access openings with a single photolithographic mask.
