Abstract: A thickness of material may be detached from a substrate along a cleave plane, utilizing a cleaving process controlled by a releasable constraint plate. In some embodiments this constraint plate may comprise a plate that can couple side forces (the “P-plate”) and a thin, softer compliant layer (the “S-layer”) situated between the P-plate and the substrate. In certain embodiments a porous surface within the releasable constraint plate and in contact to the substrate, allows the constraint plate to be secured to the substrate via a first pressure differential. Application of a combination of a second pressure differential within a pre-existing cleaved portion, and a linear force to a side of the releasable constraint plate bound to the substrate, generates loading that results in controlled cleaving along the cleave plane.

Abstract: Embodiments in accordance with the present invention relate to methods and apparatuses for bonding together substrates in a manner that suppresses the formation of voids between them. In a specific embodiment, a backside of each substrate is adhered to a front area of flexible, porous chuck having a rear area in pneumatic communication with a vacuum. Application of the vacuum causes the chuck and the associated substrate to slightly bend. Owing to this bending, physical contact between local portions on the front side of the flexed substrates may be initiated, while maintaining other portions on front side of the substrates substantially free from contact with each other. A bond wave is formed and maintained at a determined velocity to form a continuous interface joining the front sides of the substrates, without formation of voids therebetween.
