Michael Lo at iMPACT 2025

Описание: Photothermal Spectroscopy Corp is proud to announce that Michael Lo has received the Best Paper Award at iMPACT 2025, recognizing outstanding technical contributions in advanced semiconductor packaging and materials analysis.

Mike’s award-winning paper, “Identifying Sub-10 μm Unknown Organic Foreign Matters by Laser-based Optical Detection of Infrared Photoinduced Localized Mirage Effect,” was selected as the top submission among this year’s iMPACT technical papers. The work highlights how Optical Photothermal Infrared (O-PTIR) spectroscopy is transforming defect detection and chemical identification in microelectronics manufacturing.

In the paper, Mike demonstrates how O-PTIR enables the detection and identification of unknown organic foreign materials as small as sub-10 μm, delivering submicron infrared spatial resolution and high-quality IR spectra. These capabilities address a critical challenge in advanced semiconductor packaging, where even trace-level contaminants can impact device performance, yield, and reliability.

The research showcases O-PTIR’s ability to:

Identify unknown foreign materials at the sub-10 μm scale

Detect contaminants on metal contacts and within molding compounds

Deliver submicron IR spatial resolution with enhanced sensitivity

Provide chemically specific, high-quality infrared spectra for confident material identification

This work underscores the growing importance of advanced analytical techniques in modern electronics manufacturing, where rapid root-cause analysis and precise chemical insight are essential for improving yield and reducing waste.
