Claim 11:
12. A method of forming an electronic assembly for built-in self-test of a chiplet, the method comprising:
bonding a host wafer having a first circuit including a plurality of wafer transistors and a plurality of wafer passive, non-transistor devices to an encapsulation layer;
bonding a chiplet having a second circuit including a radio frequency (RF) chiplet transistor to the encapsulation layer;
forming electrical interconnects between the chiplet and wafer, wherein the electrical interconnects electrically connect the first circuit to the second circuit; and
forming an oscillator having the plurality of wafer transistors, the radio frequency (RF) chiplet transistor and the electrical interconnects, wherein the oscillator is included in a built-in self-test circuit for testing an assembly design of the electronic assembly based on the gain and/or speed of the RF chiplet transistor.
