  • METHOD FOR CHECKING AND PRODUCING A COMPOSITE OF A SUBSTRATE STACK, AND HERMETICALLY SEALED ENCLOSURE PRODUCED ACCORDING TO SAID METHOD
    Publication number: 20230274991
    Abstract: A process for producing and/or checking an assembly of a substrate stack includes: planarly arranging at least one first substrate against a second substrate to form the substrate stack, the at least one first substrate and the second substrate being arranged directly against one another or on one another, so that at least one contact area is formed between the least one first substrate and the second substrate at which the at least one first substrate is in direct planar contact with the second substrate, the at least one first substrate including a transparent material; detecting a radiative reflection which comes about through irradiation of the substrate stack with a radiative input on the at least one contact area; and ascertaining a first bond quality index (Q1) of the contact area from the radiative reflection.
