摘要:
A charged particle beam system for processing substrates is disclosed, comprising a charged particle column, combination infrared radiation and visible light illumination and imaging subsystems, in-vacuum optics, and a precision stage for supporting and positioning the substrate alternately under the charged particle column and the imaging system. The axes of the charged particle column and imaging system are offset to enable much closer working distances for both imaging and beam processing than would be possible in a single integrated assembly. A method for extremely accurately calibrating the offset between the column and imaging system is disclosed, enabling beam processing at precisely-determined locations on the substrate. The imaging system is capable of locating sub-surface features on the substrate which cannot be seen using the charged particle beam. Two illumination modes are disclosed, enabling both bright-field and dark-field imaging in infrared radiation and visible light.

In one aspect, the invention comprises a method comprising the steps of: (a) specifying a reference entity which is an obligor with respect to preferred securities; (b) defining a credit event to include deferral of dividend or coupon on the preferred securities; (c) specifying a payoff to include the preferred securities, the payoff to be made following the credit event; (d) specifying a premium; (e) executing an agreement with a protection buyer, wherein the agreement comprises terms based on the reference entity, the credit event, and the payoff, and wherein the protection buyer agrees to pay the premium in return for a promise to provide the payoff to the protection buyer upon occurrence of the credit event; and (f) receiving the premium from the protection buyer.
