Freiberg Instruments GmbH, Freiberg, Germany
Delfter Str. 6, D-09599 Freiberg, Germany

Freiberg Instruments is now one of the world’s fastest growing, young and dynamic analytical instrumentation companies with products covering a broad spectrum of applications in fields/industries like Semiconductor, Microelectronics, Photovoltaic, Dosimetry, Medical Research, Luminescence Dating, X-ray diffraction, Material Research and Electron Spin Resonance.

Established in 2005 as an university spin off from TU Bergakademie – The University of Resources, Freiberg Instruments devoted the first few years to develop and test a whole family of fast, nondestructive, electrical characterization tools under production conditions, measuring parameters like minority carrier lifetime, photoconductivity and resistivity.

MDP Microwave-Detected Photoconductivity:
The advanced method MDP is well suited for both, defect investigation by e.g. injection dependent minority carrier lifetime measurements, as well as mapping of wafers or even ingots for inline metrology. MDP has a variety of advantages in sensitivity, speed and resolution.

MD-PICTS:
MD-PICTS is a modification of MDP, where temperature dependent measurements of the defect part of the transient are accomplished. This allows to do a spatial resolved defect characterization.

BaySpec, San Jose CA, USA
1101 McKay Drive, San Jose, CA 95131, USA

BaySpec, Inc., founded in 1999 with 100% manufacturing in the USA (San Jose, California), is a vertically integrated spectral sensing company. The company designs, manufactures and markets advanced spectral instruments, including UV-VIS-NIR-SWIR spectrometers, benchtop and portable NIR/SWIR and Raman analyzers, confocal Raman microscopes, hyperspectral imagers, mass spectrometers, and OEM spectral engines and components. R&D Applications include:

Materials: Material characterization is an ideal application area for Raman spectroscopy, due to its high chemical specificity and rapid, non-contact measurement. Solid, liquid, or gaseous, nearly all materials possess a unique Raman spectral fingerprint. The technique can be readily scaled to microscopic approaches, allowing interrogation of extremely small volumes and samples, such as nanomaterials. Characterization of nanomaterials is critical to determining structural and conformational properties. Raman spectroscopy is a highly efficient technique to study the electronic properties, compositions, and mechanical stresses in these materials, all of which can manifest in Raman band shape and frequency shift.

Semiconductor: Raman spectroscopy has proven to be one of the most effective tools for characterization of semiconductor properties and for manufacturing process/quality control because materials such as Si, SiGe, InGaAs, GaAs, GaN, and graphene exhibit precise, distinct Raman bands. Applied in a microscopic approach, the Raman technique has been successfully implemented to determine microstructure composition on thin-films, strain in the multilayer device, and to identify defects across the wafer surface.

Process/Reaction: Unlike conventional UV-Vis and NIR monitoring techniques, Raman spectroscopy provides molecular specificity in real-time measurements of gas, liquid, and solid samples, both natural and synthetic. These attributes are responsible for the emerging reliance on Raman spectroscopy for a number of online process and reaction monitoring applications. Numerous sampling options, including fiber optic probes with long reach and stand-off probes for measuring inside containers and vessels make the technique adaptable to a myriad of environments and conditions.

Surface-Enhanced Raman: Surface-enhanced Raman spectroscopy (SERS) utilizes specialized metal substrates to allow Raman signal enhancement up to 10 orders of magnitude. This phenomenon occurs when the molecules of interest are in very close proximity to the metal substrate, and is generally used for evaporated solutions or particle-surface characterization. The enhanced Raman signal with SERS has extended its applications in many fields, such as biological studies, to quantify trace substances or identify very small structures such as cell surface proteins. Intracellular SERS is also possible, via the injection of metallic nanoparticles, to study internal structures and analytes.

KP Technology Ltd., Wick, Highlands and Islands, UK
Burn St, Wick, Highlands and Islands, KW1 5EH, UK

The Kelvin Probe is a non-contact, non-destructive vibrating capacitor device used to measure the work function (wf) of conducting materials or surface potential (sp) of semiconductor or insulating surfaces. The wf of a surface is typically defined by the topmost 1-3 layers of atoms or molecules, so the Kelvin Probe is one of the most sensitive surface analysis techniques available. KP Technology Systems offer very high wf resolution of 1-3 meV, currently the highest achieved by any commercial device.

KP Technology Ltd was founded with the aim of bringing to the market new surface research tools. These tools have been designed to allow specialists to investigate surface phenomena, provided equipment pathways for non-specialists and educated scientists, engineers and technologists in the capabilities of these emerging technologies.
