The semiconductor market and technologies are developing rapidly, and so far several significant developments have taken place in the area of electronics, computers, optical devices such as lasers, light-emitting diodes, and solar panels. Following the Moore’s law, the computer chip has evolved from a simple integrated circuit to a microprocessor with millions of transistors. The demand for increasingly higher performance semiconductor products has stimulated the industry to respond by producing devices with increasingly complex circuitry, more transistors in less space.
Challenges for the Semiconductor Industry
As a result, the industrial fabrication of semiconductors has become extremely complex, involving high-purity materials, sophisticated equipment, and hundreds of steps. The semiconductor industry is confronted with a daunting task of managing and co-integrating an unprecedented confluence of innovative approaches. The introduction of these innovative approaches and the new materials pose new set of concurrent, multifarious challenges both for unit process development and for process integration.
Semiconductors Meet Nanotechnology
Additionally, the semiconductor industry tries increasingly to work at the nanometer scale, and advanced semiconductor processing is already taking place well below 100nm, the threshold for nanotechnology. As the size and properties of the semiconductor devices are shrinking, it has become incredibly complex to probe down to the device level for failure analysis and other testing. In turn, there is large demand for the advanced measuring instrumental analysis which can work at smaller geometrics for the better quality control purposes.
Analysis of Semiconductor Materials
Semiconductor materials exist in many different structural forms and therefore require large range of experimental techniques for their analysis.
Specifically, Electron Microscopy techniques are used to analyze the characteristics of nano & micro device features. The high image and spatial resolution scale analysis provided by electron microscopy is particularly well suited for solving materials problems encountered during research and development, production engineering, reliability testing for failure analysis in semiconductor industries.
Basically there are two types of electron microscopy techniques that are used in materials research:
- Scanning Electron Microscopy (SEM) and
- Transmission Electron Microscopy (TEM, STEM, EELS)
Areas in Which Electron Microscopy is Needed
Electron Microscopy analysis is required in the following areas:
- Surface characterization and surface analysis
- Growth phenomena of a material deposition on silicon,
- Micro/nano-structure determination of semiconductors,
- Inter-diffusion studies on silicon after deposition of conducting layer,
- Defect detection in layers that form on top of semiconductor chips
- Stress and Strain analysis between the two layers in semiconductors
- Failure studies and analysis in semiconductor device
- Surface chemical and elemental mapping, including impurities
- Thin film thickness detection
