Adhesive bonding of semiconductor wafersWikipedia
Adhesive bonding (also referred to as gluing or glue bonding) describes a wafer bonding technique with applying an intermediate layer to connect substrates of different types of materials. Those connections produced can be soluble or insoluble. The commercially available adhesive can be organic or inorganic and is deposited on one or both substrate surfaces. The thin wafer is either mounted on dicing tape for singulation and subsequent chip-to-wafer stacking or it is bonded immediately to another device wafer for wafer-to-wafer stacking. Figure 1.
