  • Patent number: 12245381
    Abstract: Methods and systems for low-force, low-temperature thermocompression bonding. The present application teaches new methods and structures for three-dimensional integrated circuits, in which cold thermocompression bonding is used to provide reliable bonding. To achieve this, reduction and passivation steps are preferably both used to reduce native oxide on the contact metals and to prevent reformation of native oxide, preferably using atmospheric plasma treatments. Preferably the physical compression height of the elements is set to be only enough to reliably achieve at least some compression of each bonding element pair, compensating for any lack of flatness. Preferably the thermocompression bonding is performed well below the melting point. This not only avoids the deformation of lower levels which is induced by reflow techniques, but also provides a steep relation of force versus z-axis travel, so that a drastically-increasing resistance to compression helps to regulate the degree of thermocompression.

  • Patent number: 12244137
    Abstract: The described techniques address issues associated with electrostatic discharge (ESD) protection for multi-die integrated circuits (ICs). The techniques include the use of two or more semiconductor dies within a multi-die IC, which may include a first semiconductor die without ESD protection but with full ESD exposure. The first semiconductor receives ESD protection via a second semiconductor die that is integrated as part of the same package with the first semiconductor die. The second semiconductor die may be electrically more remote from ESD-exposed pins compared to the first semiconductor die. The first semiconductor die may include integrated passive devices. The second semiconductor die enables ESD protection for both semiconductor dies in the same integrated IC package.

The second contact is disposed on top of the magnetostrictive/piezoelectric ME composite element and electrically coupled to the top of the magnetostrictive/piezoelectric ME composite element. The magnetostrictive/piezoelectric ME composite element comprises a magnetorestrictive multilayer deposited on a piezoelectric layer. The magnetorestrictive multilayer produces an in-plane uniaxial magnetic anisotropy (UMA). The UMA is a twofold UMA that exhibits a symmetric radiation pattern.

  • Patent number: 12064741
    Abstract: Polymers synthesized by solid-phase synthesis are selectively released from a solid support by reversing the bias of spatially addressable electrodes. Change in the current and voltage direction at one or more of the spatially addressable electrodes changes the ionic environment which triggers cleavage of linkers that leads to release of the attached polymers. The spatially addressable electrodes may be implemented as CMOS inverters embedded in an integrated circuit (IC). The IC may contain an array of many thousands of spatially addressable electrodes. Control circuity may independently reverse the bias on any of the individual electrodes in the array. This provides fine-grained control of which polymers are released from the solid support. Examples of polymers that may be synthesized on this type of array include oligonucleotides and peptides.

  • Patent number: 12051610
    Abstract: First and second chiplets are positioned along a surface to respectively cover first and second electrodes. The first electrode is activated to cause an attraction force between the first electrode and the first chiplet. The second electrode is deactivated allowing the second chiplet to rotate on the surface. While the first electrode is activated and the second electrode is deactivated, a rotation field is applied to cause the second chiplet to be oriented at a desired orientation angle, the first chiplet being prevented from rotating by the attraction force.
