  • Patent number: 12283568
    Abstract: Alignment of devices formed on substrates that are to be bonded may be achieved through the use of scribe lines between the devices, where the scribe lines progressively increase or decrease in size from a center to an edge of one or more of the substrates to compensate for differences in the thermal expansion rates of the substrates.
