摘要： An atomic clock system employs one of a family of ion trap configurations confining an ion in a potential well, such that a vibrational frequency confined ion may be measured accurately. The ion traps disclassed for use in such atomic clock systems include configurations of ring-shaped conductive members, or sheets of conductive material having circular holes therein. The trap apparatus further has a means to apply an RF field such that the resulting electric field being generated in a space defined by the conductive members has a characteristic of a substantially quadrupole field whereby a charged particle, being injected into the space, is confined in said field, maintaining a dynamic equilibrium condition.

摘要： An optical beam transformation system includes a first and a second optical element, each of which has a non-reentrant surface. The system transforms a substantially non-uniform optical input beam (such as a Gaussian) to a substantially uniform output beam. The first and second optical elements are arranged in either a Keplerian or Galilean configuration. The aspheric surface of the second optical element is related to the aspheric surface of the first optical element by a ray-tracing function that maps substantially all of an input light beam that is incident on the first optical element to a collimated output light beam that is output from the second optical element. Preferably, the output light beam has a Fermi-Dirac intensity distribution, and the ray-tracing function maps the input light beam to the output beam out to the (1/e)6 intensity radius of the input light beam.

摘要： A method and system is provided for computing lithographic images that may take into account non-scalar effects such as lens birefringence, resist stack effects, tailored source polarizations, and blur effects of the mask and the resist. A generalized bilinear kernel is formed, which is independent of the mask transmission function, and which may then be treated using a decomposition to allow rapid computation of an image that includes such non-scalar effects. Weighted pre-images may be formed from a coherent sum of pre-computed convolutions of the dominant eigenfunctions of the generalized bilinear kernel with the appropriate mask polygon sectors. The image at a point may be formed from the incoherent sum of the weighted pre-images over all of the dominant eigenfunctions of the generalized bilinear kernel. The resulting image can then be used to perform model-based optical proximity correction (MBOPC).

摘要： An ion confinement, i.e., trap, apparatus comprises electrically conductive members, including concentric, coplanar rings or parallel sheets separated by dielectric spacers disposed on the outer edges of the sheets, each of the sheets having a circular hole, the circular holes being symmetrically aligned substantially along a common axis. The trap apparatus further has means for applying an RF potential to the conductive members, such that the resulting electric field being generated in the space defined by the conductive members has a characteristic of a substantially quadrupole field. A charged particle, being injected into the space, is confined in the field, maintaining a dynamic equilibrium condition.

摘要： An interferometer device includes a first prism portion and a second prism portion. The first prism portion has a semi-transparent surface, a beam incident surface and a beam emerging surface. The beam incident surface receives an incident light beam at a wavelength of &lgr; and at an angle of incidence &thgr; with respect to a normal to the beam incident surface. The second prism portion has a surface that corresponds to the semi-transparent surface of the first prism portion and a beam emerging surface that corresponds to the beam emerging surface of the first prism portion. The first and second prism portions are attached to each other at the semi-transparent surface of the first prism portion and the surface of the second prism portion corresponding to the semi-transparent surface. The semi-transparent surface splits the incident light beam into first and second light beams by reflecting the first beam at the semi-transparent surface and by passing the second light beam through the semi-transparent surface so that the second light beam enters the second prism portion. The first and second light beams are each respectively reflected internally to the first and second prism portions and emerge from the respective beam emerging surfaces of the first and second prism portions to form an interference pattern on a surface that has a periodicity &Lgr; that is a function of the angle of incidence &thgr; of the incident light beam, with the ratio of &Lgr;:&lgr; being greater than 2:1.
