SemiAnalysis 解析铜在芯片热管理中的优势

Being an excellent electrical conductor, copper demonstrates equally impressive thermal conductivity—surpassed other materials in its ability to transfer heat swiftly and efficiently. This rapid heat transfer makes copper the preferred material for temperature regulation and thermal management. Beyond its conductivity, copper exhibits excellent workability, allowing it to be easily reshaped through precision techniques like chemical etching and drilling. It also supports electrolytic copper plating, a process used to form microscopic surface bumps whose sizes can be finely tuned simply by adjusting the processing conditions. Together, these combined characteristics make copper a remarkably flexible and reliable metal for both thermal applications and high-density electronic engineering. (2/3)
