WebOct 28, 2004 · The OBIRCH (optical beam induced resistance change) method is an indispensable failure analysis tool in the semiconductor industry. The principle of the OBIRCH is very simple, heating and detecting resistance-change, but it has many features. The derivatives of the OBIRCH are also shown to be very useful in the failure analysis of ICs. WebThe basis of the method is the local temperature increase induced in electron-beam irradiated sample regions, given by Eq. (5) according to Castaing’s theory. The variation in temperature induces changes in the thermoelectromotive force and thermal resistance at defect sites, yielding current variations which are amplified and detected.
