About This Product

This is a device that detects hydrogen contained in minute substrates and thin films using the thermal desorption method. By using a BeCu chamber with low hydrogen solid solution and efficiently heating only the sample substrate using an infrared laser, we can suppress the increase in hydrogen background during heating and increase the amount of hydrogen desorbed from the sample. This is a device that can measure with sensitivity. Additionally, since a quadrupole mass spectrometer is used for detection, it is possible to analyze desorbed substances other than hydrogen.

■Application

・Detection of low concentration hydrogen in semiconductor substrates ・Detection of hydrogen mixed in thin film ・Detection of thermal desorption of impurity elements in micro samples ・Determination of the binding state of absorption and adsorption

■Device principle

・Local heating with infrared heating ・Temperature measurement and control using a radiation thermometer ・Low hydrogen background with BeCu chamber ・Higher sensitivity with orifice installation
