Patent
Gate structure for integrated circuit fabrication
TL;DR: In this paper, a gate stack structure has a dielectric material layer disposed on a substrate with a gate electrode disposed thereon, which enables device scaling and provides improved tunneling voltage.
Patent
Methods of fabricating an integrated circuit device with composite oxide dielectric
TL;DR: In this article, a method of fabricating an integrated circuit device includes forming a first metal oxide layer adjacent a semiconductor substrate, and a metal nitride layer, such as titanium nitride, is formed on the metal oxide surface opposite the first metal dioxide layer.
Patent
Polishing pads from closed-cell elastomer foam
TL;DR: A polishing pad formed from closed-cell elastomer foam includes a population of bubbles within the pad as the pad wears due to polishing and recedes, the freshly formed polishing surface includes pores formed of the newly exposed bubbles as discussed by the authors.
Patent
CMP system and slurry for polishing semiconductor wafers and related method
TL;DR: A chemical mechanical polishing (CMP) system includes a polishing device including polishing article as discussed by the authors, which provides relative movement between the semiconductor wafer and the polishing piece with a slurry there between.
Patent
Multi-layered titanium nitride barrier structure
TL;DR: In this paper, a multi-layer titanium barrier within an integrated contact structure is formed as multi-layered stack, which can be used as either a conventional interconnect metallization or as a nucleation structure within a tungsten plug.
