  • Process for changing the bend of anodically bonded flat composite bodies made of glass and metal or semiconductor materials
    Patent number: 5827343
    Abstract: A method for the controlled bending of anodically bonded two-dimensional composites of glass and metal or semiconductor materials. The composite is heated after bonding, for up to 200 hours to a temperature of from 250.degree. C. to Tg-10 K. As a result of this heating, controlled compaction of the glass body and, hence, bending of the composite, are achieved to reduce or reverse any distortion that has occurred during bonding.
