Compact lateral thermal resistance modeling and characterization for TSV and TSV array

Abstract: Thermal issues are among the major concerns for 3D stacked ICs, and Through silicon vias (TSVs) are used to effectively reduce the temperature of 3D ICs. Normally, TSV is considered as a good thermal conductor in its vertical direction, and its vertical thermal resistance has been studied extensively. However, lateral heat transfer of TSVs, which is also important, was largely ignored in the past. In this paper, we propose an accurate physics-based model for lateral resistance of TSVs in terms of physical and … Show more

“…Recently, the study presented in [8] shows that poorly considering TSV arrays may imply on spatial accuracy loss. The lateral thermal blockage effect caused by the thin SiO 2 insulation layer of TSVs may result in exacerbated hotspots when TSVs are placed around.…”

“…The threshold voltage shifts introduced by TSVs are less than 25 mV [ 15 ]. Thus, the pulse frequency, oxide thickness, the radius of TSVs, and the space between TSVs have been investigated [ 16 , 17 , 18 ].…”

“…A lot of numerical thermal analyses for TSVs have been done [9], [10] and recently, some analytical thermal models considering lateral thermal resistance were proposed [11], [12]. However, more efficient methods are still needed to describe and quantify metal core warming in TSVs.…”
