Anodic Bonding between K4 Glass and Si Sheet
-
摘要: 介绍了K4 玻璃与硅的阳极焊过程,分析了阳极焊的结合机理并考察了温度和电压对焊接过程的影响。结果显示,在适宜的温度和电压下,可获得良好的K4 玻璃 硅片焊接接头。焊接温度为300~ 400℃、焊接电压为700~ 800V时,焊合率较高,且焊接接头的拉伸强度高于母材的拉伸强度。K4 玻璃良好的离子导电特性,使其能够在低温和电场作用下与硅片产生良好的连接。Abstract: Anodic bonding process between K4 glass and silicon sheet is described. Effecf of bonding temperature and voltage on anodic bonding is investigated,and mechanism of anodic bonding is analyzed. The results indicate that good bonding could be realized under proper temperature and voltage conditions.The good bonding between K4 glass and silicon sheet by low temperature field assisted process is attributed to the ionic transport property of K4 glass.High bonding percentage is achieved at temperature of 300~400℃,voltage of 700~800V,and the strength of the joint is higher than that of K4 glass or silicon.
