Measurement Capabilities of X-ray Fluorescence for Bpsg Films
Deposition of borophosphosilicate glass (BPSG) films as dielectrics is one of the many steps involved in semiconductor device manufacturing. Accurate control of boron and phosphorus concentrations in these films, is essential in maintaining desired film properties. The narrowing process specification limits with the industry trend towards shrinking device sizes, is putting an increasing demand ...
متن کاملThe Bionanoprobe: hard X-ray fluorescence nanoprobe with cryogenic capabilities
Hard X-ray fluorescence microscopy is one of the most sensitive techniques for performing trace elemental analysis of biological samples such as whole cells and tissues. Conventional sample preparation methods usually involve dehydration, which removes cellular water and may consequently cause structural collapse, or invasive processes such as embedding. Radiation-induced artifacts may also bec...
متن کاملFusion Monitors For X-Ray Fluorescence X Analysis
Modern analytical laboratories require tools to assess uncertainties at every step of the analytical process. Borate fusion combined with X-Ray fluorescence has often been demonstrated to be essential for the determination of major elements in cements, ores and a large number of other matrixes. However, drift and bias contributions from the fusion technique, burner position, fluxer to fluxer, m...
متن کاملX-Ray Fluorescence Analysis of Gemstones
The energy dispersive X-ray fluorescence analysis (ED-XRFA) is a well-established tool for multielement composition analysis in different fields/1/. It works non-conducting and it is non-destructive. No particular sample preparation is necessary if the specimens have an almost planar and smooth surface. For the characterization of precious gemstone material it is also important that the deposit...
متن کاملComplexing membrane for uranium detection by total reflection X-ray fluorescence.
Selective membranes containing a few micrograms of various complexing reagents in a polyvinyl chloride (PVC) matrix were produced in order to determine low uranium concentrations in water. The membranes were produced on the surfaces of quartz glasses, and immersed in water solutions containing uranium salts (5 - 50 ng/mL). By the end of the equilibration time, the membranes were left to dry and...
