Hamamatsu develops rapid micro-LED inspection tool

MiNY PL tool detects abnormalities in external appearance, intensity and wavelength of micro-LED light emissions
Hamamatsu Photonics has developed a system for high-speed inspection of micro-LEDs on wafers. Called the MiNY PL, the tool is designed to detect abnormalities in the LED's external appearance, intensity and wavelength of their light emissions.
This inspection system uses a photoluminescence (PL) measurement technique that is based on the company's image processing technology and a newly developed imaging module.
According to the company, the MiNY PL makes fast pass/fail decisions when inspecting micro-LEDs, which will contribute to an increased product yield for use in display applications and will also help to increase the R&D efficiency of micro-LEDs.
Furthermore, the MiNY PL will also streamline the 100 percent inspection process of micro-LEDs in future mass production lines.
Secure Your Hydrogen Supply
A study supply of high-purity hydrogen is critical to semiconductor fabrication. Supply chain interruptions are challenging manufacturers, leading to production slowdowns and stoppages. On-site hydrogen generation offers a scalable alternative for new and existing fabs, freeing the operator from dependence on delivered gas.Plant managers understand the critical role that hydrogen plays in semiconductor fabrication. That important job includes crystal growth, carrier gas, wafer annealing, and in the emerging Extreme UV Lithography (EUV) that will enable new generations of devices. As the vast need for semiconductors grows across all sectors of world economies, so does the need for high-purity hydrogen.
