20120075767 | Method for Producing a Metal-Insulator-Metal Capacitor for Use in Semiconductor Devices - Methods of manufacturing metal-insulator-metal capacitor structures, and the metal-insulator-metal capacitor structures obtained, are disclosed. In one embodiment, a method includes providing a substrate, forming on the substrate a first metal layer comprising a first metal, and using atomic layer deposition with an H | 03-29-2012 |
20120092807 | Metal-Insulator-Metal Capacitor and Method for Manufacturing Thereof - The disclosure provides a method for producing a stack of layers on a semiconductor substrate. The method includes producing a substrate a first conductive layer; and producing by ALD a sub-stack of layers on said conductive layer, at least one of said layers of the sub-stack being a TiO | 04-19-2012 |
20130084700 | Method for Selectively Depositing Noble Metals on Metal/Metal Nitride Substrates - A method for forming a noble metal layer by Plasma Enhanced Atomic Layer Deposition (PE-ALD) is disclosed. The method includes providing a substrate in a PE-ALD chamber, the substrate comprising a first region having an exposed first material and a second region having an exposed second material. The first material comprises a metal nitride or a nitridable metal, and the second material comprises a non-nitridable metal or silicon oxide. The method further includes depositing selectively by PE-ALD a noble metal layer on the second region and not on the first region, by repeatedly performing a deposition cycle including (a) supplying a noble metal precursor to the PE-ALD chamber and contacting the noble metal precursor with the substrate in the presence of a carrier gas followed by purging the noble metal precursor, and (b) exposing the substrate to plasma while supplying ammonia and the carrier gas into the PE-ALD chamber. | 04-04-2013 |
20130102121 | Oxygen Diffusion Barrier Comprising Ru - A method for forming a MIM capacitor structure includes the steps of obtaining a base structure provided with a recess, the recess exposing a conductive bottom electrode plug; selectively growing Ru on the bottom electrode plug, based on a difference in incubation time of Ru growth on the bottom electrode plug compared to the base structure material; oxidizing the selectively grown Ru; depositing a Ru-comprising bottom electrode over the oxidized Ru; forming a dielectric layer on the Ru-comprising bottom electrode; and—forming a conductive top electrode over the dielectric layer. | 04-25-2013 |
