Patent ID: 6960814

Claim:
A reflecting device comprising in the following order: a substrate; a first layer; a second layer; and a third layer, said second layer comprising a stacked structure of a plurality of semiconductor layers having different lattice constants respectively, said third layer comprising a reflecting layer, said third layer having a first line, a second line, a third line and a fourth line which meet at first, second and third angles in this order at a predetermined point, and including a first region having two sides along said first line and said second line, a second region having two sides along said second line and said third line, and a third region having two sides along said third line and said fourth line, a separating groove having a depth reaching to said first layer from said third layer so as to surround said first, second and third regions in a portion excluding said first, second, third and fourth lines, and said first layer in said first, second and third regions being selectively removed, said second layer being folded in a valley shape at said first, second and fourth lines and folded in a mountain shape at said third line by a strain exerted in said second layer, said first and second regions standing on said third layer on said substrate, said third region facing said third layer on said substrate, and said first and second regions making a predetermined angle with each other.
