Claim:
1. A method for manufacturing a chip die, the method comprising providing the chip die with electrically conductive elements using a clustered position control information set for controlling an impingement position of a laser beam for application of the electrically conductive elements, wherein the clustered position control information set is created by a method comprising: receiving a specification of a set of feature positions indicating where the electrically conductive elements are to be formed on the chip die, each feature position of the set of feature positions having a first coordinate along a first direction and a second coordinate along a second direction in a plane defined by the chip die, said first direction and said second direction being mutually transverse, selecting from said set of feature positions a cluster of feature positions positioned within a two-dimensional spatial range, wherein each pair of feature positions in the cluster at least has a first minimum difference in their first coordinates or a second minimum difference in their second coordinates, removing the feature positions selected for said cluster from the set of feature positions to render a set of remaining feature positions, estimating relative positions of the set of remaining feature positions with respect to the two-dimensional spatial range in accordance with: repeating the selecting, removing and estimating until each of the feature positions in said set of feature positions is assigned to a cluster.
