  • Two-dimensional to three-dimensional VLSI design
    Patent number: 6071315
    Abstract: An apparatus and a method for producing a mask, which was derived using two-dimensional design tools, for imparting circuit designs directly on a three-dimensional surface. The method for creating the mask includes the steps of creating a two dimensional design with at least one element, establishing a location coordinate for the element using a two-dimensional coordinate system, converting the location coordinate for the element into a spacial coordinate for the element using a three-dimensional spacial coordinate system, converting the spacial coordinate for the element into a positional coordinate, and generating the mask using the positional coordinate. The apparatus for implementing three-dimensional designs using a mask, which is generated from a two-dimensional design, includes a light source and an elliptical mirror. The elliptical mirror has two focal points so that the elliptical mirror can focus a beam of light onto the three-dimensional surface.
