<p>PURPOSE:To improve the yield of thin film elements by polishing a pair of faces of the mono-crystal of bismuth silicon oxide, covering transparent electrodes on a pair of faces, and cutting the mono-crystal into multiple elements with the blade of a slicer. CONSTITUTION:Faces 2, 2' of the mono-crystal 1 of bismuth silicon oxide or bismuth germanium oxide having a pair of faces 2, 2' arranged face to face are polished. Transparent electrodes are covered on the polished faces 2, 2', and the blade of a slicer is moved in the direction of an arrow A parallel with the faces 2, 2' from a plane 3 to cut the mono-crystal 1 into multiple thin elements 4. The elements 4 can be manufactured with a high yield.</p> |
