<P>PROBLEM TO BE SOLVED: To easily and thoroughly fill a groove having a high aspect ratio with X-ray absorbing material. <P>SOLUTION: In a radiation imaging grid, a gold colloidal solution 30 is dropped and applied on an X-ray transmissive substrate 21 on which a groove 22 having a high aspect ratio is formed, in such an amount as the gold colloidal solution 30 will not overflow. The applied gold colloidal solution 30 flows into the groove 22 by capillary phenomenon. The X-ray transmissive substrate 21 is heated by a laser on an underside of a portion where the gold colloidal solution 30 is applied, so that the gold colloidal solution 30 inside the groove 22 is desiccated so that only gold colloidal particles remain inside the groove 22. The application and desiccation of the gold colloidal solution 30 is repeated until the groove 22 is filled with the gold colloidal solution 30. <P>COPYRIGHT: (C)2012,JPO&INPIT |
