Time Information

A feasibility test for real-time fine particle measurements in vacuum semiconductor processing equipment has been conducted. The approach in monitoring particles in process equipment is an installation of a sensor at a critical location inside the process equipment (hence the term ‘in-situ’) to track free particle levels in real-time. Common method for particle detection in a process chamber today is a use of test wafer with a laser wafer scanner. However, this method does not give a real time information of the particle status in the process chamber. In this paper, a new method has been developed to detect particles in real time in vacuum system for particles smaller than an optical method can detect. The system consists of a particle charging region and a particle detection region in a vacuum system. Particles with 50nm are successfully detected at about 10 torr region.

Particle Monitoring

Etching is the process where a layer is removed from a wafer surface through openings in a photoresist pattern. To monitor this process, a surface scan was employed. An in-situ particle monitor (ISPM) was installed on a plasma etch tool. The ISPM was incorporated so engineers and technicians could gain real-time information and notification of what is happening inside this tool during processing. Since ISPMs are real-time, they can catch problems as they are occurring. The ISPM detected two major problems on the plasma etch tool within a 3-wk period. The wafer scan data were monitored during this same time frame.

Observing the electronic structure, compositional change and morphological evolution of the surface and interface of a battery during operation provides essential information for developing new electrode materials for Li-ion batteries (LIBs); this is because such observations demonstrate the fundamental reactions occurring inside the electrode materials. Moreover, obtaining detailed data on chemical phase changes and distributions by analyzing an operating LIB is the most effective method for exploring the intercalation/de-intercalation process, kinetics and the relationship between phase change or phase distribution and battery performance, as well as for further optimizing the material synthesis routes for advanced battery materials. However, most conventionalin situelectrochemical techniques (other than by using synchrotron radiation) cannot clearly or precisely demonstrate structural change, electron valence change and chemical mapping information.In situelectrochemical-synchrotron radiation techniques such as X-ray absorption spectroscopy, X-ray diffraction spectroscopy and transmission X-ray microscopy can deliver accurate information regarding LIBs. This paper reviews studies regarding various applications ofin situelectrochemical-synchrotron radiation such as crystallographic transformation, oxidation-state changes, characterization of the solid electrolyte interphase and Li-dendrite growth mechanism during the intercalation/de-intercalation process. The paper also presents the findings of previous review articles and the future direction of these methods.

The Impact

The long-term performance of batteries depends strongly on the 3D morphology of electrode materials. Morphological changes, i.e., particle fracture and surface deterioration, are among the most prominent sources of electrode degradation. A profound understanding of the fracture mechanics of electrode materials in micro- and nanoscale dimensions requires the use of advanced in situ and operando techniques. In this paper, we demonstrate the capabilities of laboratory X-ray microscopy and nano X-ray computed tomography (nano-XCT) for the non-destructive study of the electrode material’s 3D morphology and defects, such as microcracks, at sub-micron resolution. We investigate the morphology of Na0.9Fe0.45Ti1.55O4 sodium iron titanate (NFTO) cathode material in Li-ion batteries using laboratory-based in situ and operando X-ray microscopy. The impact of the morphology on the degradation of battery materials, particularly the size- and density-dependence of the fracture behavior of the particles, is revealed based on a semi-quantitative analysis of the formation and propagation of microcracks in particles. Finally, we discuss design concepts of the operando cells for the study of electrochemical processes.
