Abstract
A radiator for a semiconductor includes a main body which is provided for radiating heat from the semiconductor mounted to a substrate, and a plate member attached to the main body. The plate member is provided to have an elasticity relative to the substrate. The plate member includes a plate portion that covers a part of one surface of the main body, opposite to the substrate, and four leg portions each of which extends from an outer periphery of the plate portion and is fixed to the substrate. In the radiator, the plate member effectively absorbs stress applied to the substrate.
Claims20
A radiator for a semiconductor, comprising:
- a main body which is provided for radiating heat from the semiconductor mounted to a substrate;
- and
- a plate member attached to the main body, the plate member having an elasticity relative to the substrate, wherein:
- the plate member includes a plate portion that covers a part of a top surface of the main body, opposite to the substrate, and a leg portion extending from an outer periphery of the plate portion and fixed to the substrate
- the leg portion has a base part at a boundary with the plate portion;
- the plate portion has a slit recessed from the outer periphery of the plate portion at least at an end of the base part;
- and
- the slit is provided in the plate portion covering the top surface and extends from the outer periphery of the plate portion to a location spaced from the outer periphery of the plate portion.
A radiator for a semiconductor comprising:
- a main body which is provided for radiating heat from the semiconductor mounted to a substrate;
- and
- a plate member attached to the main body, the plate member having an elasticity relative to the substrate, wherein:
- the plate member includes a plate portion having approximately a square-shaped outer periphery and covering a part of one surface of the main body opposite to the substrate, and four leg parts each of which extends from the outer periphery and is fixed to the substrate;
- the four leg parts are arranged approximately symmetrically with respect to a center of the main body;
- each of the four leg parts has a base portion continuously extending from the plate portion at the outer periphery, and includes a first plate extending from the base portion, a second plate connected with the first plate and a third plate connected with the second plate;
- the first plate has a plate surface approximately perpendicular to a plate surface of the plate portion, and the plate surface of the first plate has a width approximately equal to a thickness of the main body;
- the second plate is bent relative to the first plate while having a plate surface on the same surface as the plate surface of the first plate;
- the third plate is bent to have a plate surface that is approximately perpendicular to the plate surface of the second plate;
- and
- the third plate is attached to the substrate.
