Precision Under Pressure: Managing Materials Complexity In Advanced Packaging
By Gregory Haley - 18 Sep, 2025 - Comments: 0

In the race to extend Moore's Law through advanced packaging, the limits of precision are no longer defined solely by lithography. Increasingly, they are dictated by the unpredictable behavior of materials. Semiconductor packaging today is no longer limited to just silicon and copper. It includes an expanding range of polymers, adhesives, dielectrics, exotic metals, along with substrates suc... » read more

Making BaZrS3 Chalcogenide Perovskite Thin Films by Molecular Beam Epitaxy
By Technical Paper Link - 13 Nov, 2021 - Comments: 0

Abstract: We demonstrate the making of BaZrS3 thin films by molecular beam epitaxy (MBE). BaZrS3 forms in the orthorhombic distorted-perovskite structure with corner-sharing ZrS6 octahedra. The single-step MBE process results in films smooth on the atomic scale, with near-perfect BaZrS3 stoichiometry and an atomically-sharp interface with the LaAlO3 substrate. The films grow epitaxially via tw... » read more

Improved Performance of GaN-Based Ultraviolet LEDs with the Stair-like Si-Doping n-GaN Structure
By Technical Paper Link - 06 Oct, 2021 - Comments: 0

Abstract "A method to improve the performance of ultraviolet light-emitting diodes (UV-LEDs) with stair-like Si-doping GaN layer is investigated. The high-resolution X-ray diffraction shows that the UV-LED with stair-like Si-doping GaN layer possesses better quality and a lower dislocation density. In addition, the experimental results demonstrate that light output power and wall plug effici... » read more
