Abstract:
1. Thermal sensor apparatus for monitoring temperature in a multi-layered semiconductor package, said sensor apparatus comprising: one or more first resistor components, each of said first resistor components positioned in a different layer, and each first resistor component comprising a plurality of first linear members aligned in parallel relationship, and further comprising at least one linear array of first end connectors aligned in parallel relationship with the first linear members; a second resistor component corresponding to each of said first resistor components, each second resistor component positioned in a layer adjacent to the layer of its corresponding first resistor component, each of said second resistor components comprising a plurality of second linear members aligned in parallel relationship and at least one linear array of second end connectors aligned in parallel relationship with the second linear members; means for linking the first linear members of a first resistor component to second end connectors of the corresponding second resistor component, in order to connect the first linear members into a first conductive path; means for linking the second linear members of a second resistor component to first end connectors of the corresponding first resistor component, in order to connect the second linear members into a second conductive path; means for serially connecting each of said first and second conductive paths into a single continuous conductive path; and a device responsive to electric current sent through said continuous path for determining temperature proximate to said continuous path from said path resistance.
