高k介质材料(High-k dielectric materials)指的是介电常数(或称相对介电常数)较高的材料。介电常数是衡量材料对电场响应的能力的一个重要物理量,简而言之,它表示材料在电场作用下的电容储存能力。 1. 什么是介电常数(k值)? 介电常数(k值)是一个无量纲的数值,用来描述某种材料相对于真空在电场中存储电能的能力...
Unique dielectric compositions may be used to formulate thick film pastes for printing microelectronic capacitors. The resulting dielectrics exhibit dielectric constants greater than about 500 and capacitances greater than about 80,000 picofarads per square inch at a thickness of at least about 1.0 ...
