Abstract:
1. A method of fabricating a semiconductor device, the method comprising: providing an assembly substrate including a split plane defining a handle region and a transfer region, a film layer coupled to the transfer region, and one or more active devices coupled to the film layer; providing a device substrate including one or more bonding regions, wherein the one or more bonding regions include one or more receptor sites; joining the assembly substrate to the device substrate, wherein joining the assembly substrate to the device substrate comprises directly bonding the film layer to a portion of the device substrate and directly bonding the one or more active devices to the one or more receptor sites of the device substrate, and wherein at least a portion of the film layer is suspended over a cavity formed between the one or more active devices directly bonded to the one or more receptor sites and the portion of the device substrate directly bonded to the film layer; and splitting the assembly substrate to remove the handle region.
