Title: X-ray exposure method
Inventor: SASAKI MASAYOSHI
IPC: G21K1/06
Filed: 1986-10-29
Abstract: PURPOSE:To shorten time for X-ray exposure, by forming a single-crystal layer on a surface of a single-crystal matter for X-ray reflection so that their lattice constants are different from each other. CONSTITUTION:When silicon (non-doped silicon) containing no impurity is used for a single-crystal substrate 11 and when silicon (phosphorus-doped silicon) containing 10<18> to 10<21>/cm<3> of phosphorus as impurity is used for a single-crystal epitaxial layer 12, for example, epitaxial growth of these elements can be facilitated and a lattice constant of the phosphorus-doped silicon is made to be smaller by 0.5% or so than that of the non-doped silicon. Therefore, when thickness of the phosphorus-doped silicon is made about half the thickness of depth in which X-rays invade crystal, reflective X-rays can be obtained from two single-crystal matters whose lattice constants are slightly different from each other. This single-crystal layer is an epitaxial layer of either CaF2 or NiSi2. Thus, time for X-ray exposure is shortened.
