Successful failure isolation from front side becomes very expensive and time consuming as the technology nodes becoming increasingly difficult. Electro Optical Techniques, composed of Electro Optical Frequency Mapping (EOFM) and Probing (EOP), are dynamic optical analysis techniques. Most EOP/EOFM applications have focused on design debug or design characterization of integrated circuits (ICs ...

The paper describes as integrated technique of Electro Optical Frequency Mapping (EOFM) and Electro Optical Probing (EOP) to localize open failure mode with traditional FA analysis approach. The technique was performed in analog devices on advanced SOI-based circuits.

2017年7月1日 · EOP (Electro Optical Probing) / EOFM (Electro Optical Frequency Mapping) is a dynamic optical probing technique widely used in IC level defect localization from backside. In this paper, a new method… Expand

2014年9月1日 · Electro-Optical Probing (EOP) technique is undeniably powerful in internal device’s signal studies. From the backside of the devices, the incident and reflected laser beam interact with each layer of the Device Under Test (DUT). More specifically, EOP can probe analog waveforms that cannot be measured by Time Resolved Imaging (TRI) [1].

Electro-optical techniques are the standard techniques for contactless fault isolation in modern IC's. And because these modern IC's are composed of FinFETs, th.

2017年7月1日 · Electro-optical frequency mapping (EOFM) is an optical probing technique that allows creating a 2-D activity map of circuits, showing nodes that are switching at a...
