used to separate each layer 160 162 164 from the layer contacts 190 430 432 434 436 438 440 of the other layers 160 162 164 and the other layers 160 162 164 themselves in one example the insulator 412 416 418 420 422 426 is a silicon dioxide dielectric insulation layer in one example the die 102 and the separate layer 310 may not to be the same material and therefore may not have the same expansion coefficients when the die 102 and the separate layer 310 are connected together and thermal changes or any other expansion contraction force occur the die 102 will expand contract by one amount and the separate layer 310 expands contracts by another amount different from that of the amount of the die 102 when the amount of expansion contraction is different in the die 102 than in the separate layer 310 there will be a stress applied at the connection of the die 102 and the separate layer 310 this stress is relieved at the connection between the die 102 and the separate layer 310 by the flexing of the compliant component 114 in one example as shown in fig1 and 8 the stress applied to the connection is likely to be in a radial direction from to the midpoint 158 of the die 102 to from the electrical interface component 130 in one example the flexible arm 710 attached to the electrical interface component 130.
