Abstract

A stereolithographically fabricated marking for a semiconductor device component, such as a packaged or unpackaged semiconductor device or another substrate. When the marking is formed on a semiconductor device with a stereolithographically formed package structure, the marking may be integral with the package structure. The marking may be formed as apertures through or recessed areas in one or more stereolithographically fabricated layers of material. Alternatively, the marking may include one or more stereolithographically fabricated layers that protrude from a surface of a semiconductor device component. The marking may be formed directly on a surface of a packaged or bare semiconductor device component. As an alternative, the marking can be fabricated separately from a semiconductor device component, then secured thereto. Methods of stereolithographically marking semiconductor device components are also disclosed. The stereolithographic method may include use of a machine vision system including at least one camera operably associated with a computer controlling a stereolithographic application of material so that the system may recognize the position and orientation of a semiconductor device or other substrate that is to be stereolithographically marked.
