Optical beam induced resistance change (OBIRCH) is an imaging technique which uses a laser beam to induce a thermal change in the device. Laser stimulation highlights differences in thermal characteristics between areas containing defects and areas which are defect-free. As the laser locally heats a defective area on a metal line which is carrying a current, the resulting resistance changes can be detected by monitoring the input current to the device. OBIRCH is useful for dete… WebMay 29, 2024 · Resistance Change: a term that has crossed over from optical probing techniques, which describes a condition where the total resistance measured across a sample is temporarily changed due to the action of the electron The origin of this reversible change may be local heating, charging or others. daihan hygro-thermo
