This invention belongs to the field of semiconductor device manufacturing and layout design technology. It provides a layout connection structure design method to improve the metal stripping process of indium gallium arsenide (IGaAs) detectors. The method employs an inverted trapezoidal stepped electrode edge optimization, forming a gradual slope along the direction perpendicular to the substrate. Rounded transitions are used at the corners of the electrode pattern. Small closed patterns to be stripped are connected to surrounding large patterns via connecting strips. The inverted trapezoidal slope of the connecting strips matches the electrode pattern. The connecting strips avoid the effective area of ​​the detector, with a minimum distance of ≥4µm from the effective electrode. The number of connecting strips is set according to the minimum area pattern distribution density, with one connecting strip shared by every 2-5 small closed patterns. This reduces contaminant generation by more than 98%, fundamentally lowering the risk of electrode contamination and scrapping. It is directly compatible with existing Ti / Pt / Au multilayer metal stripping processes. The connecting strip parameters can be flexibly adjusted according to different electrode sizes, making it suitable for detector production in various fields such as optical communication and spectral detection.
