What Is Undercut Etching at Will Bracy blog

What Is Undercut Etching. A considerable amount of research has been carried out to explain this convex corner. The possible reasons for the undercut problem is the diffusion of active species at the mask and silicon interface; In wet anisotropic etching, the etched profile of undercut convex corners depends on the type of etchant. Undercut is a critical nonideal effect that causes a higher lateral etching rate of the sidewalls beneath masks, which reduces the flatness and uniformity of the. Undercuts from etching can occur from two common causes. The most commonly way to remove the copper is through a process called etching. Get anisotropic etching and little undercutting because of directed ion flux. In pcb fabrication process, copper has to be removed from solid copper sheets for realizing conductive traces. Need both components for etching to occur. As figure 3 shows, the actual sides of a trace are curved, and an etching “undercut” is below the blue resist. Etch factor is the ratios of etch depth to the amount the resist is undercut during etching. The first is over etching, which means the etchant was applied too long.
