− ラジエータをリンクする材料とチップの後面4(能動面5の反対側の面)との間の界面3の抵抗率R1。この界面は概して、ネイティブシリカ6の断熱効果を避けるようにチップ1の後面上の金属堆積によって形成されており、このネイティブシリカ6は多かれ少なかれこのシリコン面上を覆い、かつ抵抗率が高い。これらの材料は、タングステンWの合金、およびチタンTiの合金、またはニッケルNiの合金、クロムCrの合金、および金Auの合金などとすることができる。
− 熱交換素子2への機械的リンクを確保する材料7の抵抗率R2。この材料は、例えば、(熱伝導率が約5W/m/℃から20W/m/℃まで様々な)熱接着剤、または(熱伝導率が35から50W/m/℃まで様々な)多少鉛リッチな半田とすることができる。
− 熱交換素子2のリンクを確保するために熱交換素子2の上に堆積された材料8の抵抗率R3。この材料は、例えば、真空下で実行された金属堆積とすることができる。
