Abstract
A semiconductor apparatus includes a rectangular plate-like body including a major surface. A plurality of light emitting portions formed in the major surface, and aligned in a straight line. A first terraced portion and a second terraced portion are formed in the major surface except areas in which the plurality of light emitting portions are formed.
Claims21
A semiconductor apparatus comprising:
- a rectangular plate-like body including a first long side, a second long side parallel to the first long side, a first short side, and a second short side parallel to the first short side and including a major surface;
- a plurality of light emitting portions formed in the major surface, and aligned in a straight line;
- and
- a first terraced portion and a second terraced portion which are formed in the major surface except areas in which the plurality of the light emitting portions are formed, the areas including a first longitudinal end portion of the body and a second longitudinal end portion opposite to the first longitudinal end portion of the body,
- wherein the first terraced portion is formed in the first longitudinal end portion leaving a first peninsula-shaped portion, the first terraced portion extending to the first short side and to the first long side, the first peninsula-shaped portion extending to the first short side and to the second long side;
- wherein the second terraced portion is formed in the second longitudinal end portion leaving a second peninsula-shaped portion, the second terraced portion extending to the second short side and to the first long side, the second peninsula-shaped portion extending to the second short side and to the second long side;
- wherein the first terraced portion extends over a first area along the first peninsula-shaped portion, the first area being larger than a gap between two adjacent light emitting portions;
- and
- wherein the second terraced portion extends over a second area along the second peninsula-shaped portion, the second area being larger than the gap between two adjacent light emitting portions.
