Title: Sputtering target
Inventor: ISHIGAMI TAKASHI
IPC: C23C14/14
Filed: 2000-03-10
Abstract: PROBLEM TO BE SOLVED: To obtain a highly reliable semiconductor element, and at the same time, make increase in the degree of integration of the element sufficiently capable by suppressing the leakage current of the element, through formation of a high-purity conductive film the Al content of which is adjusted to a specific number of atoms or lower. SOLUTION: A high-purity conductive film, the Al content of which is suppressed to about 1×1018 atoms/cm3 or lower expressed in terms of number of atoms is formed. The reason why the Al content is suppressed to the value is that the leakage current in a semiconductor element increases as the Al content increases beyond the specifications, and as the junction depth between the source and the drain regions becomes deeper, because currents are apt to be affected by the Al contained in a contact barrier layer, but when the Al content is suppressed to about 1×1018 atoms/cm3 or lower, the leakage currents can be suppressed to nearly constant low values, regardless of the junction depth of the source and drain region.
