  • Patent number: 10892233
    Abstract: Moisture-driven degradation of a crack stop in a semiconductor die is mitigated by forming a groove in an upper surface of the die between an edge of the die and the crack stop; entirely filling the groove with a moisture barrier material; preventing moisture penetration of the semiconductor die by presence of the moisture barrier material; and dissipating mechanical stress in the moisture barrier material without presenting a stress riser in the bulk portion of the die. The moisture barrier material is at least one of moisture-absorbing, moisture adsorbing, and hydrophobic.

  • Patent number: 10804181
    Abstract: Embodiments of the present invention relate to an heterogenous thermal interface material (TIM). The heterogenous TIM includes two or more different materials. One material has a low elastic modulus, also known as Young's modulus, and is utilized primarily to transfer heat from one component to another component. Another material has a higher elastic modulus and is primarily utilized to bond or connect the corners and/or edges of one component to the other component. The high elastic modulus material is generally located within the heterogenous TIM where TIM strain is or is expected to be high. For example, the high elastic modulus material may be located at the corner and/or edge regions of the heterogenous TIM.
