TitleMaterials Innovation for Future Electronics

AbstractInternet of things demand further performance improvements in integrated circuit systems. Two approaches exist for in future IC fabrication. One is to continue the transistor scaling (Moore’s Law) with either new device architectures or using new materials with superior gate controllability [1]. Another approach is to construct three-dimensional integrated circuits (3D ICs) with monolithic integration; for example, adding sensor functionalities, or constructing upper-layer logic circuits or memory devices on CMOS Si wafers, or stacking logic with memory devices [2]. Therefore, the research on materials and processes compatible with the backend-of-line (BOEL) fabrication temperature (< 400 oC), is needed. Here, I like to discuss on few potential components for achieving monolithic 3D ICs including 2D layered semiconducting materials, and hexagonal boron nitride (hBN) insulators [3]. The detailed growth mechanism and growth strategy such as step edge epitaxy [4] for these 2D materials shall be discussed. These components enable the monolithic 3D integration.

單位簡介

本系的重點研究領域包括:凝態物理、光電與奈米科學、高能與粒子物理、軟凝態物理與生物物理、原分子光學物理、及物理科學教育等。本系前身為臺灣省立師範學院理化系物理組,成立於民國三十五年(1946年)本校創校之始。民國五十一年(1962年)本系獨立成系,民國六十三年(1974年)成立物理研究所碩士班,民國八十年(1991年)成立研究所博士班。長久以來,本系肩負著培育臺灣中等學校物理科師資的重任,但也不忘在物理學術研究上求新求進步。至今本系培育出的學術人才已有一位中研院院士及近百位中研院研究員及大學教授,各行各業的高科技人材更是不勝枚舉。民國八十三年師資培育法改制後,本系已升級為尖端學術研究、科技應用研發、及中學師資培育三者齊備的系所。
