4CeeD: Real-Time Data Acquisition and Analysis Framework for Materials and Semiconductor Fabrication Cyber-Physical Environments

4CeeD: Real-Time Data Acquisition and Analysis Framework for Materials and Semiconductor Fabrication Cyber-Physical Environments

Klara Nahrstedt (University of Illinois at Urbana-Champaign)


Materials and Semiconductor Fabrication research heavily depends on experimental laboratories equipped with scientific instruments such as Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM) and others. IN may laboratories these microscopes are stand-alone devices, producing extensive digital data and metadata and, yielding high volume, high variety and high velocity data. The scientific process at these instruments is as follows: The materials or semiconductor fabrication researcher brings a flash drive to the scientific instrument, copies the most important and clean data on his/her memory stick, and then walks to his/her office to put the data on his/her laptop for further processing. After the data evaluation, and publishing the scientific findings, the data is put on a tape and stored on a researcher’s bookshelf.

In this talk, I will discuss 4CeeD, the networked microscopes cyber-physical infrastructure, running a distributed service for real-time acquisition, streaming, and cloud-based real-time  analysis  of materials and semiconductor fabrication data, enabling scientists from Material Research Laboratory (MRL) and Micro-and-Nano-Technology Laboratory (MNTL) at UIUC to speed up  in multiple orders of magnitude their scientific discovery. We will discuss the unique cyber-physical requirements of networked microscopes, and their impact on digital data and metadata representations, analysis and architectural design of cloud storage to enable timely processing, communication and delivery of data to scientists. 4CeeD is a distributed infrastructure-as-a-service (IaaS) with an optimized real-time acquisition, transmission and analysis service architecture to break the ineffective process of scientists at the start of their scientific discoveries.
