  • Publication number: 20210285829
    Abstract: The invention relates to a coating comprising at least one functional decorative layer. The decorative layer comprises a thermochromic composition exhibiting a reversible variation of optical and/or colorimetric properties when part or all of the coating is subjected to a temperature variation between a cold temperature and a hot temperature, the cold temperature being between 0° C. and 40° C. and the hot temperature being between 80° C. and 400° C., and comprising at least one thermochromic compound of the family of silver halides. The invention also relates to a functional decorative layer composition, to an article comprising the coating or the decorative layer composition, and to the use of the coating or the decorative layer composition as a temperature indicator.

  • Patent number: 9847243
    Abstract: A process for making a device comprising a thin functional substrate comprising bonding the functional substrate to a carrier substrate, forming functional components on the functional subsrate, and debonding the functional substrate from the carrier substrate by applying ultrasonic wave to the bonding interface. The application of ultrasonic wave aids the debonding step by reducing the tensile stress the functional substrate may experience.

  • Patent number: 8697228
    Abstract: A carrier (31) for a thin glass sheet (7) is disclosed. The carrier includes an elastomer (9) which has first (15) and second (17) opposed surfaces and a support (11) bonded to the first surface (15) of the elastomer (9). During use, the thin glass sheet (7) directly contacts and is releasably bonded to the elastomer's second surface (17). In order to provide a strong, yet releasable bond to the thin glass sheet (7), the elastomer's second surface (17) has a Shore A hardness in the range of 10-90 and a roughness less than or equal to 185 nanometers. In this way, the carrier/glass sheet assembly (13) is able to withstand the conditions encountered during manufacture of electronic components on the exposed surface (23) of the thin glass sheet (7).
