    Abstract
    One of main challenges of 3D-integration is the area overhead which has two main causes: first the huge TSV diameter which is usually in the range of microns, and the second reason is the Keep-Out-Zone (KOZ) overhead due to the high induced thermal stresses during fabrication. The area overhead besides the fabrication process itself inversely affects the overall yield and fabrication cost, so the increase in area will reduce the yield and increase the fabrication cost. In this paper, the effect of KOZ overhead on the overall area, yield, and fabrication cost is investigated. Also various parameters that might change KOZ overhead are examined. We show that the share of area overhead caused by KOZ is considerably higher compared to that of TSVs. Further, the impact of KOZ is considered for obtaining more accurate estimation on W2W overall yield and fabrication cost of a 3D-IC.
