WebAnnealing and Planarizing. David J. Elliott, in Ultraviolet Laser Technology and Applications, 1995 Metal Interconnection Layers. There are several metals used or interconnection layers in electronic circuits that require or can benefit from planarization in multilevel IC interconnection schemes; aluminum and aluminum alloys are commonly used. Device yield or die yield is the number of working chips or dies on a wafer, given in percentage since the number of chips on a wafer (Die per wafer, DPW) can vary depending on the chips' size and the wafer's diameter. Yield degradation is a reduction in yield, which historically was mainly caused by dust particles, however since the 1990s, yield degradation is mainly caused by process variation, the process itself and by the tools used in chip manufacturing, although dust still rema…
