Abstract

A new 3D micromachining method called Hole Area Modulation(HAM), has been introduced to enhance the current micromachining technology. In this method, information on the depth of machining is converted to the sizes of small holes in the mask. The machining is carried out with a simple 2D movement of the workpiece. This method can be applied for machining various kinds of microcavities in various materials. In this paper, a machematical model for excimer laser micromachining based on HAM and also determination of optimal laser ablation conditions(width hole radius, step size, path, etc.) is performed by Genetic Algorithm(GA).
