Title: An x-ray lithography device
Inventor: KUMAKHOV MURADIN ABUBEKIROVICH
IPC: G03B42/02
Filed: 2001-04-03
Abstract: An invention relates to a contact lithography device and comprises a soft X-ray source (preferable as an X-ray tube 1 with a rotating anode), a half lens 2 for a divergent radiation of this source transforming to a quasi-parallel one (the said lens includes a set of channels for a radiation transporting with total external reflection, the said channels are oriented along a generatrix of barrel-shaped surfaces), the means for placing a mask 3 and a substrate 4 with a resist 5 applied on it (the said means are placed on the output face side of a half lens 2), and an absorbing filter 6 for smoothing a nonuniformity of a beam intensity of an emergent radiation of a half lens, presenting in intensity decreasing as from the center to the periphery of a beam. An absorbing filter 6 is placed between the radiation source 1 and the input face of a half lens 2, and a relationship of cross sizes of a half lens and its focal distance from the input side is chosen so that to provide a capture angle of a source radiation in the following limits:   0,7/E1.5 <= .PSI. <= 1.3/E1.5, where .PSI. is an angle of a radiation capture [rad];      E is radiation energy of the used source [keV].   The reflecting surface of the channels for a radiation transporting is made of a material which includes elements with an atomic number not more than 22, and radiation energy of the used source is 0,6-6 keV. Owing to the increased capture angle and an absorbing filter placing before the input of a half lens, efficiency of a source radiation using increases and, simultaneously, an area of a plate-substrate under processing magnifies and lens longevity increases.

Abstract: An electronic slot machine game is set forth which includes an on-screen bonus and one or more separate screen bonuses. A processor randomly selects to activate a coordinate of a game matrix having one or more pay lines. The coordinate remains activated until a bonus is triggered.   When a triggering symbol is randomly assigned to an activated coordinate, an on-screen bonus is issued. When the bonus is issued, all activated coordinates are de-activated. The bonus is related to the amount wagered to play the game, the number of activated coordinates and assigned values or multipliers. Second screen bonuses are triggered by scattered symbols or symbols on enabled pay lines and include a game themed screen for the player to select from a plurality of hidden bonuses or issues a random bonus accompanied by an entertaining video segment.
