Abstract: Dielets on flexible and stretchable packaging for microelectronics are provided. Configurations of flexible, stretchable, and twistable microelectronic packages are achieved by rendering chip layouts, including processors and memories, in distributed collections of dielets implemented on flexible and/or stretchable media. High-density communication between the dielets is achieved with various direct-bonding or hybrid bonding techniques that achieve high conductor count and very fine pitch on flexible substrates. An example process uses high-density interconnects direct-bonded or hybrid bonded between standard interfaces of dielets to create a flexible microelectronics package. In another example, a process uses high-density interconnections direct-bonded between native interconnects of the dielets to create the flexible microelectronics packages, without the standard interfaces.

Abstract: Structures and techniques provide bond enhancement in microelectronics by trapping contaminants and byproducts during bonding processes, and arresting cracks. Example bonding surfaces are provided with recesses, sinks, traps, or cavities to capture small particles and gaseous byproducts of bonding that would otherwise create detrimental voids between microscale surfaces being joined, and to arrest cracks. Such random voids would compromise bond integrity and electrical conductivity of interconnects being bonded. In example systems, a predesigned recess space or predesigned pattern of recesses placed in the bonding interface captures particles and gases, reducing the formation of random voids, thereby improving and protecting the bond as it forms. The recess space or pattern of recesses may be placed where particles collect on the bonding surface, through example methods of determining where mobilized particles move during bond wave propagation.

Abstract: Direct-bonded native interconnects and active base dies are provided. In a microelectronic architecture, active dies or chiplets connect to an active base die via their core-level conductors. These native interconnects provide short data paths, which forgo the overhead of standard interfaces. The system saves redistribution routing as the native interconnects couple in place. The base die may contain custom logic, allowing the attached dies to provide stock functions. The architecture can connect diverse interconnect types and chiplets from various process nodes, operating at different voltages. The base die may have state elements for drive. Functional blocks aboard the base die receive native signals from diverse chiplets, and communicate with all attached chiplets. The chiplets may share processing and memory resources of the base die. Routing blockages are minimal, improving signal quality and timing. The system can operate at dual or quad data rates.

The bonded structure can include security circuitry extending across the bond interface, the security circuitry electrically connected to the first and second semiconductor elements.

Abstract: Techniques and arrangements for performing exposure operations on a wafer utilizing both a stepper apparatus and an aligner apparatus. The exposure operations are performed with respect to large composite base dies, e.g., interposers, defined within the wafer, where the interposers will become a part of microelectronic devices by coupling with active dies or microchips. The composite base dies may be coupled to the active dies via “native interconnects” utilizing direct bonding techniques. The stepper apparatus may be used to perform exposure operations on active regions of the composite base dies to provide a fine pitch for the native interconnects, while the aligner apparatus may be used to perform exposure operations on inactive regions of the composite base dies to provide a coarse pitch for interfaces with passive regions of the composite base dies.
