Title: Integrated circuit metallisation process with improved step covering - uses same metal, with preferential deposition on polycrystalline silicon@, for contact plus and interconnection pattern
Inventor: OHNO YOSHIKAZU
IPC: H01L27/108
Filed: 1991-04-26
Abstract: The metallisation pattern for a semiconductor device with insulating layer (12) and contact windows (12a) features deposition of a polySi layer (13) by Chemical Vapour Depsn. (CVD), which is then etched into an interconnection pattern. On the polySi pattern a metal layer (15) is deposited preferentially, using pref. W, Mo or Cu. Also claimed is the process for the metallisation of DRAMs, especially to form the bitlines. USE/ADVANTAGE - The process reduces the danger of partial or open contacts between contact plugs and interconnection pattern, and makes use of the excellent step-coverage features of polySi layers. In currently available IC's the plugs and interconnection are made of different metals and require other processing steps between depositions. which can cause formation of oxide layers. This may result in partial or complete open circuits. The process is especially useful in high density and large scale IC's with reduced dia. contact windows e.g. large capacity DRAMs.
