Abstract: In some embodiments, the present disclosure relates to a wafer edge trimming apparatus that includes a processing chamber defined by chamber housing. Within the processing chamber is a wafer chuck configured to hold onto a wafer structure. Further, a blade is arranged near an edge of the wafer chuck and configured to remove an edge potion of the wafer structure and to define a new sidewall of the wafer structure. A laser sensor apparatus is configured to direct a laser beam directed toward a top surface of the wafer chuck. The laser sensor apparatus is configured to measure a parameter of an analysis area of the wafer structure. Control circuitry is to the laser sensor apparatus and the blade. The control circuitry is configured to start a damage prevention process when the parameter deviates from a predetermined threshold value by at least a predetermined shift value.

The method includes forming a first plurality of interconnect layers within a first dielectric structure on a front-side of a first substrate and forming a second plurality of interconnect layers within a second dielectric structure on a front-side of a second substrate. A first redistribution layer coupled to the first plurality of interconnect layers is bonded to a second redistribution layer coupled to the second plurality of interconnect layers along an interface. A recess is formed within a back-side of the second substrate and over the second plurality of interconnect layers. A bond pad is formed within the recess. The bond pad is laterally separated from the first redistribution layer by a non-zero distance.

Abstract: Various embodiments of the present application are directed to a method for forming a thin semiconductor-on-insulator (SOI) substrate at low cost and with low total thickness variation (TTV). In some embodiments, an etch stop layer is epitaxially formed on a sacrificial substrate. A device layer is epitaxially formed on the etch stop layer and has a different crystalline lattice than the etch stop layer. The sacrificial substrate is bonded to a handle substrate, such that the device layer and the etch stop layer are between the sacrificial and handle substrates. The sacrificial substrate is removed. An etch is performed into the etch stop layer to remove the etch stop layer. The etch is performed using an etchant comprising hydrofluoric acid, hydrogen peroxide, and acetic acid.
