Title:

LASER RADIATION -- A TOOL FOR INTEGRATED CIRCUIT EXAMINATION AND INTERFERENCE

This talk presents research results on the effects of irradiating semiconductor devices (SD) and integrated circuits (IC) with lasers. We show that the adequate simulation of the phenomena occuring requires the joint numerical solution of both the optical equations as well as the fundamental semiconductor physics equations in a two-dimensional approximation. Simulations with our "DIODE-2D" software have shown that laser irradiation can be an effective tool for SD and IC investigation and influencing. It may be used to ionize separate components to define their reaction or change state. The numerical simulation helps to identify optimal laser-beam parameters, such as the wavelength, pulse width, location etc. Numerous examples presented will illustrate the capabilities of SD and IC laser irradiation.
