  • Patent number: 11205622
    Abstract: To overcome the problem of devices in a multi-chip package (MCP) interfering with one another, such as through electromagnetic interference (EMI) and/or radio-frequency interference (RFI), the chip package can include an electrically conductive stiffener that at least partially electrically shields the devices from one another. At least some of the devices can be positioned in respective recesses in the stiffener. In some examples, when the devices are positioned in the recesses, at least one device does not extend beyond a plane defined by a first side of the stiffener. Such shielding can help reduce interference between the devices. Because device-to-device electrical interference can be reduced, devices on the package can be positioned closer to one another, thereby reducing a size of the package. The devices can electrically connect to a substrate via electrical connections that extend through the stiffener.
