    • A stacked 3D integrated circuit structure is manufactured with a common image design for dies which allows diced master dies to cut from the common wafer and diced slave dies cut to be cut from a wafer which has the common image design. In an embodiment is stacked to form a wafer-to-wafer 3D stack before dicing. Master and slave elements which are used for only one kind of separated individual integrated circuit dies which are located along die edges and at die centers before dicing separation of individual integrated circuit chips. A master wafer is shifted ½ way across a die to make cutting along a kerf line effective to provide both master and slave dies. Multiple slaves can be stacked and coupled to a master die which acts as a bus master when attached to a bus to which only the master die is directly connected. The use of a common wafer design minimizes cost of manufacture of chips destined to be stacked as 3D integrated circuits.
    • 制造堆叠的3D集成电路结构,其具有用于管芯的公共图像设计,其允许切割的主管芯从公共晶片切割并切割成具有共同图像设计的晶片切割的切割从属裸片。 在一个实施例中,在切割之前堆叠以形成晶片到晶片3D堆叠。 主单元和从元件仅用于单个集成电路芯片切割分离之前沿着芯片边缘和模具中心位置的一种分离的单独集成电路管芯。 主晶片沿模具移动1/2路,以便沿着切割线进行切割有效地提供主模和从模。 多个从器件可以堆叠并耦合到主引脚,当连接到仅母模直接连接的总线时,主器件用作总线主器件。 使用普通晶圆设计可最大限度地降低作为3D集成电路堆叠的芯片的制造成本。
