Therefore the system herein achieves both CT compatibility and radiation beam compatibility.

A method is disclosed for the implementation of phase shifting masks for EUV lithography. The method involves directly etching material away from the multilayer coating of the mask, to cause a refractive phase shift in the mask. By etching into the multilayer (for example, by reactive ion etching), rather than depositing extra material on the top of the multilayer, there will be minimal absorption loss associated with the phase shift.

A titania-doped quartz glass suited as an EUV lithographic member is prepared by feeding a silicon-providing reactant gas and a titanium-providing reactant gas through a burner along with hydrogen and oxygen, subjecting the reactant gases to oxidation or flame hydrolysis to form synthetic silica-titania fine particles, depositing the particles on a rotating target, and concurrently melting and vitrifying the deposited particles to grow an ingot of titania-doped quartz glass. The target is retracted such that the growth front of the ingot may be spaced a distance of at least 250 mm from the burner tip.

This invention describes a novel beam arrangement for multiview and dual view x-ray or radiation scanning systems used for inspection of objects. The method described herein is especially suited for scanning large objects such as palletized cargo or dense objects that are longer in one dimension, for example the height being larger than the width or depth. As the size and density of the object to be scanned increase, the absorption of the x-rays by the object increases with less of x-rays reaching the detectors. Therefore, in order to receive minimal signal for acceptable image quality, the scan speed is slowed which for certain objects it might become so low that it may not be acceptable. This invention describes a novel beam arrangement that greatly speeds up the scan speed.
