Compliant Die Attach Process for High‐Conformity Integration of Ultra‐Thin Chips on Curved Surfaces
Advanced Materials Technologies, EarlyView.A compliant die attach process is developed for bonding ultra‐thin silicon dies onto high‐curvature surfaces. Using FEM‐guided tool design and process optimization, the method achieves excellent surface conformity and minimal voids. This approach offers a reliable solution for next‐generation curved electronics, including LiDAR and wide field‐of‐view ...

Advanced Materials Technologies, EarlyView.A theoretical framework links stress‐induced changes in the Young's modulus of Fe₇₂Ga₂₈ layers to their magnetization dynamics under SH‐SAW excitation. This interaction produces a sharp sensor response near the coercive field, highlighting FeGa's magnetoelastic sensitivity.

Co‐Solvent‐Aided Opto‐Thermophoretic Printing of Gold Nanorod Assemblies
Advanced Optical Materials, EarlyView.A focused laser beam creates a thermal gradient, driving the gold nanorods and polymer coils toward the heated region of the glass substrate, i.e, the laser spot. After the adsorption of the polymer on the gold surface, the nanorods start to assemble onto the surface in a ring‐shaped pattern that grows radially until the beam is turned off.
