Field Emission Scanning Electron Microscope Featuring Ultra-high Resolution Imaging
Hitachi High-Technologies Corporation (TOKYO: 8036, Hitachi High-Tech) announces the development and worldwide launch on April 19, 2011, of the SU9000, a new type of Field Emission Scanning Electron Microscope (FE-SEM) capable of ultra-high resolution imaging. The SU9000 is equipped with a newly developed electron source that enables ultra-high resolution observations, while minimizing sample damage caused by electron beams during observations.
SEMs are utilized in an array of fields, ranging from semiconductor devices, electronics, and advanced nanotechnology materials, to life sciences and medicine. SEMs from Hitachi High-Tech play an especially critical role in the field of semiconductor analysis, where they are indispensable for observing micro-level structures a) at the R&D stage, b) as part of production-floor process control, and c) in defect analysis. SEMs capable of supporting advanced technology of this kind require a number of important features beyond the capacity for outstanding high-resolution observations. These include the ability to perform observations using low accelerating voltages (Vacc), which minimize the sample damage caused by electron beams; throughput on the level of 100 or more observations a day; and stable operability that consistently allows for this performance.
The SU9000 is equipped with a new type of cold FE electron source for ultra-high resolution observations, an area of strength for Hitachi. Compared to previous versions, this new cold FE electron source is stable used for long periods, from right after startup with no wait times. The probe current within this stable range is approximately double that of earlier models, enabling bright images with superior S/N performance to be taken. Furthermore, Hitachi's unique in-lens technology improves resolution under low accelerating voltage (1 kV) to 1.2 nm, and guarantees STEM resolution (optional) that can image the lattice structure of graphite (C (002) d=0.34 nm) at an accelerating voltage of 30 kV.
The SU9000, while performing as an SEM boasting world-leading resolution of 0.4 nm (30 kV:SE image as of April 2011), also adopts a side-entry method for introducing samples for observation. This technique reduces the time for sample exchanges and the time to obtain a high-resolution photo to around 6 minutes or less*1, permitting high-throughput data acquisition. The SU9000 also employs proprietary signal detection that enables high-contrast observations that can be tailored to the observation task, such as evaluation of morphology or composition. This new FE-SEM also has a large 24.1-inch widescreen monitor offering a comfortable environment for operating the device, as well as a new interface that enhances usability. Together, these innovations have delivered an environment that facilitates user operations.
Shipments are scheduled to commence from the first half of 2011.
