Abstract

The invention is to a mounting device (12) and to a method of mounting a semiconductor die (11) to a mounting surface (10) to ensure that the die (11) is in a plane parallel to the mounting surface (10). An intermediate woven mounting device (12) having two parallel faces and having a plurality of co-planer mounting points (13a and 14a) on each of the parallel faces is placed on a semiconductor mounting surface (10) and the semiconductor die (11) is placed on the intermediate device. Along with a die attach adhesive, heat and pressure is applied to secure the semiconductor die (11) and intermediate mounting device (12) to the mounting surface (10).
