Abstract: Some implementations described herein include systems and techniques for fabricating a wafer-on-wafer product using a filled lateral gap between beveled regions of wafers included in a stacked-wafer assembly and along a perimeter region of the stacked-wafer assembly. The systems and techniques include a deposition tool having an electrode with a protrusion that enhances an electromagnetic field along the perimeter region of the stacked-wafer assembly during a deposition operation performed by the deposition tool. Relative to an electromagnetic field generated by a deposition tool not including the electrode with the protrusion, the enhanced electromagnetic field improves the deposition operation so that a supporting fill material may be sufficiently deposited.

The first/second optical component set emits the second/third second-stage light to a first/second position of an eye and receives a first/second reflected light. The first/second detector receives a first/second detection light.

Abstract: An image-recognition assisting method includes the steps of using an examination instrument to generate an image having a split-image area formed thereon; setting a region-of-interest (ROI) around the split-image area of the generated image; performing a pixel luminance addition processing on the ROI, so that all pixels in the ROI have increased luminance contrast; and performing a contrast correction on the ROI having increased luminance contrast, so that the luminance contrast between the split-image area and the area surrounding the split-image area in the ROI is further increased. The image-recognition assisting method optimizes the image generated by the conventional ophthalmic examination instrument, such as a fundus camera, to increase the sharpness and the luminance contrast of the image output by the fundus camera, so that an examiner can easily recognize two offset rectangular image parts in the split-image area and align them with each other to focus the examination instrument.

Abstract: A fundus examination device aiding in gaze fixation and image focusing includes a light projecting device for projecting an examination light to illuminate an examinee's fundus; an illuminating system for transmitting the examination light to the examinee's eye and receiving a fundus image; an imaging system for showing the fundus image; and a focusing and gaze-fixation device located in the illuminating system and including a focus mask formed in a focusing zone, on which the examinee's eye focuses. The focus mask includes a split image screen surrounded by a light-penetrable structure, and gaze fixation devices for forming gaze-fixation images at examinee's eye focusing positions within the focusing zone, such that the split image screen and the gaze-fixation images are located at different focal positions corresponding to the examinee's eye curvature. Therefore, when a split image focusing is completed, the gaze-fixation images are also located at clearly recognizable focal positions.

From the intensity and position of the reflected light, x-, y- and z-axis relative positions between the examinee's pupil and the objective lens are obtained. An examiner adjusts the relative positions in three axes until they fall within an allowable deviation range, and a clear fundus image can be obtained.
