Abstract: Reliable hybrid bonded apparatuses are provided. An example process cleans nanoparticles from at least the smooth oxide top layer of a surface to be hybrid bonded after the surface has already been activated for the hybrid bonding. Conventionally, such an operation is discouraged. However, the example cleaning processes described herein increase the electrical reliability of microelectronic devices. Extraneous metal nanoparticles can enable undesirable current and signal leakage from finely spaced traces, especially at higher voltages with ultra-fine trace pitches. In the example process, the extraneous nanoparticles may be both physically removed and/or dissolved without detriment to the activated bonding surface.

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. A recess may be repeated in a stepped reticule pattern at the wafer level, for example, or placed by an aligner or alignment process.

Abstract: A method of forming a sealing structure for a bonded wafer is provided. The method includes providing the lower wafer and the upper wafer, forming a sealing material layer on each of the lower wafer and the upper wafer, forming a mask layer on the sealing material layer on each of the lower wafer and the upper wafer, etching the sealing material layer using the mask layer as an etch mask, so as to form a first protrusion at an edge of the lower wafer and a second protrusion at an edge of the upper wafer, and bonding the first protrusion and the second protrusion together to form the sealing structure. The sealing structure encloses a gap between the lower wafer and the upper wafer at an edge of the bonded wafer, so as to form a hermetically sealed cavity at the edge of the bonded wafer.
