## Abstract Erosionβcorrosion tests on copper and three types of copper alloys in a 1 wt% solution of CuCl~2~ were carried out at various flow velocities using a jetβinβslit testing apparatus, which is capable of reproducing various hydrodynamic conditions. A damage profile of a specimen was develo
When copper interconnection is applied in practical ULSI devices, it is required to fill holes and trenches with high aspect ratios with copper. A high deposition rate of 100 nm/min as well as complete gap filling at an aspect ratio of 3 was obtained in deposition of copper by chemical vapor deposit
