Overview


LTA-2200EP/F is Kobelco Research Institute's carrier lifetime measurement system. It uses the μ-PCD (microwave photoconductivity decay) method.

It detects, by microwave reflection, how carriers (electrons and holes) injected into the wafer by a laser decrease over time. The differential μ-PCD method can also measure epitaxial layers grown on low-resistivity substrates.

It handles Si, SiC and GaN wafers and LTPS and IGZO thin films, producing maps quickly at a standard pitch of 0.5 mm. It is used to evaluate crystal perfection and heavy-metal contamination.
