WebOptical beam induced resistance change (OBIRCH) is a powerful tool for localization but has resolution limitations due to the diameter of the optical beam. The tool can be further improved by the lock-in technique. In this paper we demonstrate that the lock-in technique can also be applied for electron beam localization methods like electron ... WebAbstract: In this paper, cross-sectional TEM combined with plan-view TEM analysis was employed to investigate the gate oxide integrity (GOI) failure isolated using infrared optical beam induced resistance change (IR-OBIRCH) method. The cross-sectional TEM investigation only shows gate oxide breakdown and fused active under the spacer.

WebApr 1, 2024 · Conventional Optical Beam Induced Resistance Change (OBIRCH) uses a constant voltage bias and current detection configuration to monitor current changes by using a low noise and high gain current amplifier. Current changes are consequences of resistance variation when the voltage bias is maintained constant. WebMay 1, 1999 · Backside Optical Beam Induced Resistance Change (OBIRCH) [3] has been shown recently to localize shorted conductors, but the detection sensitivity is limited. To overcome the limitations of existing techniques, we have developed a new scanning optical microscopy (SOM) imaging method which directly localizes both open and shorted ...
