中文简介:
电子元件的显著进步使最近的电子器件得到了巨大的发展。尤其是在电路中,电瓷在与集成电路的配合中发挥了重要作用。组件的主要主题是功能性、小型化、体积效率、可靠性、安全材料和更低的价格。为了开发出性能更高的新型陶瓷元件,对陶瓷的形态设计进行了多项研究工作。电子器件的功能性是利用陶瓷的特定形态如体(三维)、板(2-D)、纤维(1-D)和粒子(0-D)来发展的。在陶瓷材料和工艺技术的配合下,器件设计取得了显著进展。多层膜是设计由电介质、压电、磁学、半导体和绝缘体陶瓷组成的陶瓷器件的最常用技术。如何制备厚度小于0.3mm的介电层是陶瓷电容器工程中的一项重要工作。通过将无源元件嵌入多层陶瓷和聚合物基片,实现了小型化的三维模块电路。为了改善陶瓷的电性能,发展了核壳、晶轴排列等陶瓷结构的形貌控制方法。为了提高非铅铁电材料的压电性,通常采用纹理取向和超高磁场的方法。纳米颗粒的自组装是构建超晶格结构和裁剪功能更强的材料和器件的一项具有挑战性的技术。介绍了陶瓷纳米颗粒的制备和表征。
课程简介: Remarkable progress of the electronics components enabled the tremendous development of the recent electronics devices. In particular, the electro-ceramics has played an important role in cooperate with IC in the circuits. The major subjects for the components have been functionality, miniaturization, volumetric efficiency, reliability, safety materials and lower price. Several research works on morphology designing of the ceramics has been done to develop the new components with higher performance. The functionality of the electronics devices has been developed using specific morphologies of the ceramics such as bulk (3-Dimention), plate (2-D), fiber(1-D) and particle (0-D). Device designing has been remarkably progressed in cooperate with ceramic materials and process technologies. Multilayer is a most popular technology to design the ceramics devices consist of dielectric, piezo-electric, magnetic, semiconductor and insulator ceramics. How we can prepare the thinner dielectric layer than 0.3mm is a most important work for the ceramic capacitor engineering. Miniaturized 3-D module circuits are realized by embedding the passive components into the multiplayer ceramic and polymer substrates. Morphology control of the ceramic structure such as core-shell and arrangements of crystal axis has been developed to improve the electric performances. To enhance the piezoelectricity of the non-lead ferroelectric materials, textured grain orientation and ultra high magnetic field application are known as useful process methods. Self-assembling of the nano-particles is a challenging technology to build-up the super lattice structure and tailoring the more functional materials and devices. Preparation and characterization of the ceramic nano particles are presented.
