EMIB copper layer for signal and power routing

Abstract:

Embedded Multi-die Interconnect Bridge (EMIB) technology provides a bridge die, where the EMIB includes multiple signal and power routing layers. The EMIB eliminates the need for TSVs required by the SIP assembly silicon interposers. In an embodiment, the EMIB includes at least one copper pad. The copper pad may be configured to protect the EMIB during wafer thinning. The copper pad may be connected to another copper pad to provide signal routing, thereby increasing the signal contact density. The copper pad may be configured to provide an increased power delivery to one or more connected dies.
