Abstract: An electronic assembly has a host wafer having a first circuit including wafer transistors and passive, non-transistor devices. Chiplets have a second circuit including at least one radio frequency (RF) transistor device. Electrical interconnects are between the chiplets and wafer. The electrical interconnects electrically connect the first circuit to the second circuits. Oscillators that have the wafer transistor, the RF transistor and the electrical interconnects produce a signal for built-in self-test circuits for testing an assembly design of the electronic assembly and speeds of the RF chiplet transistors.

Abstract: An electronic assembly has a host wafer having a first circuit including passive devices for the purpose of one of tuning or matching networks. Chiplets are placed in the cavities. At least one chiplet has a second circuit including at least one transistor or switch device and passive tuning circuits including at least one of a stabilization network, a gain boosting network, a power delivery network, or a low-noise network. Electrical interconnects between the chiplets and wafer electrically connect the first circuitry to the second circuitry.

Abstract: An electronic assembly has a backside capping layer, a host wafer having a back surface bonded to a top surface of the backside capping layer except for cavities in the wafer formed over areas of the backside capping layer, the cavities having side surfaces of the wafer. Chiplets have backsides bonded directly to at least portion of the areas of the top surface of the backside capping layer. A lateral dielectric material between side surfaces of the chiplets and side surfaces of the wafer, mechano-chemically bonds the side surfaces of the chiplets to the side surfaces of the wafer.
