High speed sub-micron thermal imaging system
Submicron spatial resolution
As semiconductor technology has advanced, the size of semiconductor elements has become very small, down to a few micrometers. To measure heat distribution accurately during operation, a resolution smaller than one micrometer is needed. Previous IR methods could not achieve better than 15 micrometers due to physical limits, but AccuOptotech’s new system uses visible light to reach sub-micrometer resolution.
High speed
The main issue with measuring temperature using visible light is that it’s very slow. A regular spectrometer takes about 200ms per point for Si and 2s per point for GaN.For a 100×100 µm² area, this means it would take 1 hour 10 minutes for Si and 22 hours for GaN to get a full temperature map.To fix this, AccuOptotech developed a new spectroscopic system that is 50 times faster
Simultaneous measurement of substrate and channel temperature in GaN on Si devices
IR thermal imaging can only measure surface temperature, so it cannot detect the temperature inside a substrate.AccuOptotech’s system solves this by simultaneously measuring the temperature of GaN (the active part) and Si (the substrate) in LEDs and power semiconductors. This works even with transparent GaN and opaque Si.This helps with thermodynamic analysis by providing both channel and substrate temperatures, making it easier to find and fix thermal issues.
SERS Membrane
A typical SERS template has metal nanoparticles on an opaque base, and the sample is placed on top for measurement. AccuOptotech’s SERS membrane is thin, transparent, and easy to transfer onto a sample using heat. This makes it possible to analyze semiconductor and plate-like samples, which were difficult to measure with traditional SERS templates. It allows for faster and easier SERS analysis. The membrane can be cut to any size and easily removed. Additionally, the Ag nanoparticles are protected by a special coating, preventing oxidation and keeping them stable for a long time. The membrane also provides consistent results, works across a wide range, and enhances Raman signals effectively.
