摘要:
The present invention relates a probe forming lithography system for generating an pattern on to a target surface such as a wafer, using a black and white writing strategy, i.e. writing or not writing a grid cell, thereby dividing said pattern over a grid comprising grid cells, said pattern comprising features of a size larger than that of a grid cell, in each of which cells said probe is switched “on” or “off, wherein a probe on said target covers a significantly larger surface area than a grid cell, and wherein within a feature a position dependent distribution of black and white writings is effected within the range of the probe size as well as to a method upon which such system may be based.

The present invention relates to a lithography system for projecting an image or an image pattern on to a target such as a wafer. Energy that is accumulated in the target by the projection of the image or image pattern is removed from said target, such that expansion by local and/or overall heating is limited to a relevant pre-defined value, and wherein such heat removal is realised by the use of a phase transition in a heat absorbing material that is brought into thermal contact with said target. As a further elaboration, such material may be applied in combination with a further material having a superior coefficient of heat transport, and may be incorporated in an emulsion comprising a material having a superior coefficient of heat transfer. Said material may e.g. be adhered to a bottom face of the target, and may also be included in a frame.
