Abstract: Proton beams can deliver a highly targeted radiation dose to a narrow volume defined by their Bragg peaks. However, Bragg peak range uncertainties persist during dose delivery. Fortunately, pulsed proton beams generate protoacoustic emissions proportional to absorbed proton energy, thereby encoding dosimetry information in a detectable acoustic wave. The present embodiments provide methods and apparatuses to derive and model protoacoustic imaging with an ultrasound transducer, and examine the frequency characteristics of protoacoustic emissions, which are crucial parameters in imaging resolution.

Abstract: A semiconductor package includes a die and a first lamination layer on the die with openings through the first lamination layer. A redistribution layer is on the first lamination layer and extends through the openings to the die. A plurality of conductive extensions are on the redistribution layer with each stud including a first surface on the redistribution layer, a second surface opposite to the first surface, and a sidewall between the first surface and the second surface. A second lamination layer is on the redistribution layer and the first lamination layer with the die encapsulated in molding compound. The second lamination layer is removed around the conductive extensions to expose the second surface and at least a portion of the sidewall of each stud to improve solder bond strength when mounting the package to a circuit board.
