摘要:
A polymer solder hybrid (PSH) thermal interface material (TIM). The PSH TIM includes a solder with a low melt temperature and a filler with a high melt temperature. Upon initiation of reflow, the filler diffuses into the solder to form a new filler-solder alloy having an increased melting point and added robustness.
摘要:
Embodiments of the present invention provide various polymeric matrices that may be used as a binder matrix for polymer solder hybrid thermal interface materials. In alternative embodiments the binder matrix material may be phophozene, perfluoro ether, polyether, or urethane. For one embodiment, the binder matrix is selected to provide improved adhesion to a variety of interfaces. For an alternative embodiment the binder matrix is selected to provide low contact resistance. In alternative embodiments, polymeric materials containing fusible and non-fusible particles may be used in application where heat removal is desired and is not restricted to thermal interface materials for microelectronic devices.
摘要:
Formulations and processes for forming wafer coat layers are disclosed. In one embodiment, an organic surface protectant is incorporated into a wafer coat formulation deposited onto a semiconductor wafer prior to the laser scribe operation. Upon removal of the wafer coat layer, the organic surface protectant remains on the bumps and thereby prevents oxidation of the bumps between die prep and chip and attach. In an alternative embodiment, an ultraviolet light absorber is added to the wafer coat formulation to enhance the wafer coat layer's energy absorption and thereby improve the laser's ability to ablate the wafer coat layer. In an alternative embodiment, a conformal wafer coat layer is deposited on the wafer and die bumps, thereby reducing wafer coat layer thickness variations that can impact the laser scribing ability.
摘要:
A thermal interface material is described for thermal coupling of an electronic component to a thermally conductive member. The thermal interface material includes a viscoelastic polymer matrix material, fusible solder particles in the matrix material, and filler particles in the matrix material. The solder particles have a melting temperature below a selected temperature (e.g. 157° C. for indium) and the filler particles have a melting temperature substantially above the selected temperature (e.g. 961° C. for silver). The filler particles keep the thermal interface material intact under adverse thermal and stress conditions.
