Patent ID: 8153923

Claim:
A method for producing a hole in a layer system, comprising: producing a hole outer diffuser initial contour that approximately represents a final outer diffuser contour, while leaving a diffuser buffer layer of material between the initial outer diffuser contour and the final outer diffuser contour; producing a hole lower region concentric with the outer diffuser that approximately represents a final hole lower region contour, while leaving a lower region buffer layer of material between the initial lower region contour and the final lower region contour, wherein at least one of the hole outer diffuser initial contour and the hole lower region that approximately represents a final hole lower region contour is produced using a pulsed electron beam or a pulsed laser beam comprising a first pulse length; and producing a final contour on the hole outer diffuser by removing the diffuser buffer layer and the hole lower region by removing the lower region buffer layer, wherein at least one of the final contour on the hole outer diffuser and the hole lower region is produced using a pulsed electron beam or a pulsed laser beam comprising a second pulse length that is different than the first pulse length.
