Electronics

Every year, hundreds of consumer electrical and electronic goods get recalled, dealing serious reputational and financial damages to brands and retailers. Electronics testing is done to not only determine the quality and safety of an electronic, as well to comply with international regulations. 

Typical materials involved in advanced thin-film devices are semiconductors, metal alloys, dielectrics, oxides, and polymers. This mandates accurate monitoring and control of the device parameters using multiple investigation techniques. X-ray fluorescence (XRF) and X-ray diffraction (XRD) are an integral part of any such manufacturing process to monitor and control critical thin film parameters at every step equally important is the fine control over the process materials, like CMP slurry, which is an indispensable part of any thin-film device manufacturing. In most of these, the particle size and shape play an important role and need reliable characterization.

Measurement types

Particle size distribution

Particle size analysis in the range 0.01-3500 microns. For nanoparticle analysis see dedicated section.

Morphology

Morphological analysis of particles in the range 0.5-10000 microns (size, shape and transparency of particles). Integrated Raman chemical analysis with MDRS (Morphologically Directed Raman Spectroscopy).

Nanoparticle characterization

Size, concentration and zeta potential anlysis of nano-systems using light scattering techniques such as DLS, ELS and NTA techniques.

Rheology, Viscosity and Powder Flowability

Viscosity measurement and visco-elastic properties characterization of liquid dispersions, complex fluids and semi-solid materials.

Elemental analysis

XRF provides both qualitative and quantitative information on a wide variety of sample types. It can quantify elements from beryllium (Be) up to americium (Am) in concentrations from 100% down to sub-ppm level.

Phase identification

Phase identification is the most important application of X-ray diffraction (XRD). It is not only applied on powder samples but also on polycrystalline solids, suspensions and thin films.

Polymer characterization

Gel permeation chromatography (GPC) that separates analytes on the basis of size, typically in organic solvents. The technique is often used for the analysis of polymers.
