    摘要： A medical imaging system and method. A UV/visible camera uses a back illuminated silicon imaging detector to observe a surface of a brain of a human subject in vivo during brain surgery for excision of a cancerous tumor. The detector can be a CCD detector or a CMOS detector. Under UV illumination, the camera can record images that can be processed to detect the location and extent of a cancerous tumor because the presence of auto-fluorescent NADH variations can be detected between normal and cancerous cells. The image data is processed in a general purpose programmable computer. In some instances, an image is also taken using visible light, and the identified cancerous region is displayed as an overlay on the visible image.

    摘要： A back-illuminated silicon photodetector has a layer of Al2O3 deposited on a silicon oxide surface that receives electromagnetic radiation to be detected. The Al2O3 layer has an antireflection coating deposited thereon. The Al2O3 layer provides a chemically resistant separation layer between the silicon oxide surface and the antireflection coating. The Al2O3 layer is thin enough that it is optically innocuous. Under deep ultraviolet radiation, the silicon oxide layer and the antireflection coating do not interact chemically. In one embodiment, the silicon photodetector has a delta-doped layer near (within a few nanometers of) the silicon oxide surface. The Al2O3 layer is expected to provide similar protection for doped layers fabricated using other methods, such as MBE, ion implantation and CVD deposition.

    摘要： A back-illuminated silicon photodetector has a layer of Al2O3 deposited on a region of a silicon oxide surface that is left uncovered, while deposition is inhibited in another region by a contact shadow mask. The Al2O3 layer is an antireflection coating. In addition, the Al2O3 layer can also provide a chemically resistant separation layer between the silicon oxide surface and additional antireflection coating layers. In one embodiment, the silicon photodetector has a delta-doped layer near (within a few nanometers of) the silicon oxide surface. The Al2O3 layer is expected to provide similar antireflection properties and chemical protection for doped layers fabricated using other methods, such as MBE, ion implantation and CVD deposition.
