  • Patent number: 12283531
    Abstract: A control circuit is included in a first die of a stacked semiconductor device. The first die further includes a transistor that is electrically connected to the control circuit. The transistor is configured to be controlled by the control circuit to selectively block a die-to-die interconnect. In this way, the die-to-die interconnect may be selectively blocked to isolate the first die and a second die of the stacked semiconductor device for independent testing after bonding. This may increase the effectiveness of a testing to identify and isolate defects in the first die or the second die, which may further increase the effectiveness of performing rework or repair on the stacked semiconductor device.

  • Patent number: 12270968
    Abstract: The invention is related to contact lenses that not only comprise the much desired water gradient structural configurations, but also have a minimized uptakes of polycationic antimicrobials and a long-lasting surface hydrophilicity and wettability even after going through a 30-days lens care regime. Because of the water gradient structural configuration and a relatively-thick, extremely-soft and water-rich hydrogel surface layer, a contact lens of the invention can provide superior wearing comfort. Further, a contact lens of the invention is compatible with multipurpose lens care solutions present in the market and can endure the harsh lens care handling conditions (e.g., digital rubbings, accidental inversion of contact lenses, etc.) encountered in a daily lens care regime. As such, they are suitable to be used as weekly- or monthly-disposable water gradient contact lenses.
