Filed: 1999-12-31
Abstract: PURPOSE: A method of manufacturing an interconnect is to remove the process of forming a tungsten contact plug, thereby reducing an operating time. CONSTITUTION: The first interconnect(11) is formed on a source region and a drain region. An IMD(inter metal dielectric) layer(12) is formed on the first interconnect. The IMD layer is made of a conductive material such as SiO2, using a CVD(chemical vapor deposition) process. A contact hole is then formed by photo-etching. The IMD layer is etched to form a new contact hole, using a photoresist pattern(13) as a mask. By this etching, the surface of the first interconnect is exposed. If the later contact hole is doped with the conductive material, a barrier layer(15a) is formed. To obtain the second interconnect layer(16a) and an upper interconnect layer(16b), the barrier layer is subjected to sputtering. To connect MOSFET with each other electrically, the second barrier layer(16) is formed by etching sequentially the second interconnect layer, the upper interconnect layer and the barrier layer.

Abstract: A safe, reliable SCR system for reducing NO x emissions from a lean-burn internal combustion engine utilizes urea in aqueous solution. Overheating and hydrolysis of the solution are prevented by maintaining the temperature of the urea solution sufficiently low that it is not permitted sufficient time at elevated temperature to hydrolyze the urea to such an extent that solids precipitate. In a preferred embodiment, an injector system similar to those used for fuel injection provides a constant feed to injectors (32) and a return line (33). The feed and injection can be controlled to provide sufficient urea for NO x reduction and sufficient cooling capacity for the feed and injection system to avoid hydrolysis and deposits of hydrolysis products.
