Representative techniques provide process steps for forming a microelectronic assembly, including preparing microelectronic components such as dies, wafers, substrates, and the like, for bonding. One or more surfaces of the microelectronic components are formed and prepared as bonding surfaces. The microelectronic components are stacked and bonded without adhesive at the prepared bonding surfaces.

Representative implementations provide techniques and systems for processing integrated circuit (IC) dies. Dies being prepared for intimate surface bonding (to other dies, to substrates, to another surface, etc.) may be processed with a minimum of handling, to prevent contamination of the surfaces or the edges of the dies. The techniques include processing dies while the dies are on a dicing sheet or other device processing film or surface. Systems include integrated cleaning components arranged to perform multiple cleaning processes simultaneously.

A process flow for bonding a die to a substrate incorporates defectivity risk management and yield promotion by reducing flow complexity. In some embodiments, the process flow may include a radiation process on a component substrate to weaken an adhesive bonding of dies from a surface of the component substrate, a first wet clean process on the component substrate after the radiation process to clean die bonding surfaces, eject and pick processes after performing the first wet clean process to remove dies from the component substrate for bonding to a substrate, a plasma activation process on the substrate, a second wet clean process after the plasma activation process on the substrate to clean a substrate bonding surface of the substrate, and a hybrid bonding process to bond die bonding surfaces of the dies to the substrate bonding surface of the substrate.
