Abstract
PURPOSE:To absorb secondary electrons generated from a foundation layer by the irradiation with X rays by a secondary-electron absorbing layer, and to prevent the unnecessary sensitization of an X-ray resist by secondary electrons by forming the secondary-electron absorbing layer between the foundation layer to be worked on a semiconductor substrate and the X-ray resist. CONSTITUTION:A foundation layer 3 to be worked, a flattening layer 4 shaped for removing irregularities on a semiconductor substrate 1, a secondary-electron absorbing layer 6 consisting of SiN and an X-ray resist 5 are formed successively onto a pattern 2 shaped in a preprocess on the semiconductor substrate 1. The secondary-electron absorbing layer 6 absorbs secondary electrons generated when the foundation layer 3 to be worked composed of a high melting point metal receives X rays, and has no effect of secondary electrons on the X-ray resist 5, and secondary electrons are absorbed by the layer 6, and material simple substances in atomic numbers of thirty or less or these complexes are preferable as materials difficult to generate secondary electrons by the irradiation with X rays and substances such as C, SiN, Al2O3, BN or the like are effective.
