Abstract We describe a technique that is used to obtain timing information from laser assisted device alteration (LADA). The technique uses a non-pulsed laser scanning microscope to obtain timing information with a temporal resolution on the order of microseconds. Custom software is used to extract the timing information from the LADA images.

Abstract We present an upgraded time-resolved LADA system, with a 25ps pulsed laser, integrated into a commercial laser scanning microscope used in failure analysis. We demonstrate the use of this system on 14nm/16nm finfet devices.

Abstract In this paper, we describe improved hardware to connect a semiconductor tester or applications board to a laser scanning microscope (LSM) for performing dynamic laser stimulation (DLS). The hardware, called DXGlue, simplifies the DLS workflow and enables new applications. We describe its precise monitoring of the fail rate and fail mode, its use for time resolved DLS and the enabling of long test loops with short laser dwell times.

Light microscopic techniques for visualizing biomolecules and biochemical processes in situ have become indispensable in studies concerning the structural organization of supramolecular assemblies in cells and of processes during the cell cycle, transformation, differentiation, and development. Confocal laser scanning microscopy offers a number of advantages for the in situ localization and quantitation of fluorescence labeled targets and probes: (i) rejection of interfering signals emanating from out-of-focus and adjacent structures, allowing the “optical sectioning” of the specimen and 3-D reconstruction without time consuming deconvolution; (ii) increased spatial resolution; (iii) electronic control of contrast and magnification; (iv) simultanous imaging of the specimen by optical phenomena based on incident, scattered, emitted, and transmitted light; and (v) simultanous use of different fluorescent probes and types of detectors.We currently use a confocal laser scanning microscope CLSM (Zeiss, Oberkochen) equipped with 3-laser excitation (u.v - visible) and confocal optics in the fluorescence mode, as well as a computer-controlled X-Y-Z scanning stage with 0.1 μ resolution.
