Measurement of Axisymmetric Crystallographic Texture

January 1, 2009
Author(s)
Mark D. Vaudin
Crystallographic texture has for many years been the fiefdom of metallurgists and geologists, who have developed elegant methodologies for the analysis of highly complex textures and texture evolutions. Over the past two decades, the importance and

Micrometer-width damascene copper conductors at e10 MA/cm2

January 1, 2009
Author(s)
David T. Read, Roy H. Geiss
We have applied high amplitude (~10 MA/cm2) alternating current (AC) at 100 Hz and direct current (DC) to copper interconnect lines with widths in the few-micrometer range covered with a thick layer of SiO2. Under our test conditions of Joule heating, the
