Abstract: The present invention relates to the formation of multiple gettering structures within a semiconductive substrate by ion implantation through recesses in the semiconductive substrate. A preferred embodiment of the present invention includes forming the recesses by using a reactive anisotropic etching medium, followed by implanting a gettering material. The gettering material is implanted by changing the gettering material for the reactive anisotropic etching medium. An advantage of the method of the present invention is that gettering structures are formed without the cost of an extra masking procedure and without the expense of MeV implantation equipment and procedures. As a result, metallic contaminants will not move as freely through the semiconductive substrate in the region of an active area proximal to the gettering structures.
