Isotropic Etching

Isotropic etching is a process used in manufacturing, especially in electronics, where material is removed uniformly in all directions. Imagine shaping a sculpture by gently erasing material equally from every surface, resulting in smooth, rounded edges. This technique uses chemicals or solutions that dissolve the material consistently, regardless of its orientation. It contrasts with anisotropic etching, which favors specific directions. Isotropic etching is useful for creating features with rounded shapes or when uniform material removal is desired for precise control in fabrication processes.
