发明名称 Coplanar die to substrate bond method
摘要 A coplanar die to substrate bond method wherein a plurality of die are aligned on a silicon wafer substrate in a predetermined relationship and a slurry of glass is applied to bond them together. This occurs while either on a flat or a grooved plate. When the silicon wafer substrate and the plurality of die are ready for firing, they are placed on a grooved plate so that grooves are below the glass thereby decreasing the capillary force which commonly causes overflow. With reduced overflow, the bonding can be done at a higher temperature to reduce underflow. Because there is no underflow or overflow using this process, a greater degree of coplanarity is achieved thereby making future processing steps, such as the processing of interconnect lines, much easier to perform.
