Definitions
- This invention relates generally to the dissipation of thermal energy generated by semiconductor devices, such as memory chips.
- Cooling of semiconductor devices can be achieved by immersing the devices in a suitable liquid coolant. However, these cooling techniques can result in corrosion of the device and substrate metallurgy, and also present rework problems. Cooling can also be achieved by using a fan to create forced air convection. However, system level requirements sometimes prohibit fan usage due to reliability. Cooling can also be achieved by providing a conducting link of material between the device and the cap or cold plate.

- FIG. 4 shows a top view of the attachment system of FIG. 3 through a heat sink used in the electronic heat sink system of FIGS. 1 and 2 .
- FIG. 5 shows a top view of an alternative embodiment of the attachment system of FIG. 3 .
- a heat generating electronic device such as a microprocessor 15 , which has a die 20 , which may be non-compressive and thermally conductive, placed on a first surface 25 (i.e., shown as a top surface herein) thereof, also has a second surface 30 (i.e., shown as bottom surface) opposite the first surface 25 .
- the microprocessor 15 may have a plurality of connectors (not shown) attaching thereto as is known in the art.
- the microprocessor 15 is typically attached to a cold plate 35 by soldering 40 or the like.
- a heat sink 45 is placed in register with the microprocessor 15 .
- the heat sink has a flat body 47 having a recess 48 therein.
- the recess 48 has a plurality of radial edges 49 that lead to an inner surface 51 therein. Unless a spring is used, as will be discussed infra, a recess 48 may not be desired.
- the attachment system 50 has a thermally conductive slug 55 that has a body 60 that may be made of copper or the like and that is generally rectangular and rigid.
- the slug 55 can be any shape but generally conforms to the shape of the die 20 of the microprocessor to ensure the efficiency of heat transfer away from the microprocessor 15 .
- the body 60 is also rectangular or other shaped.
- the body 60 in this instance shown, has four side edges 65 .
- Strips 70 are thermally conductive, generally flexible or bendable and have a width W and a length L.
- Each strip 70 has a proximal edge portion 71 attaching to an edge 65 of the body 60 .
- Each strip has a distal edge portion 73 , which may be rigid having a portion 85 facing towards the heat sink 45 , and has a depth D.

- Thermal layer 90 which may be an adhesive or grease thermally connects the slug 55 to the die 20 .
- Each strip 70 may have a particular composition so that each strip acts as a spring to urge the slug 55 against the compressive die 20 to ensure contact between the slug 55 and the die 20 .

- the frame has the same number of sides as there are strips 70 .
- the frame 110 attaches to the flat body 47 either inside or outside of the recess 48 .
- the spring 95 is disposed in the recess 48 between the slug 55 and the flat body 47 .
