  • 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.

    Wafer-level integration has the advantage of higher throughput enhanced cleanliness and the flexibility that standard fab equipment can be used for further processing. 3D integration applying chip-to-wafer bonding focuses on the yield ("good known die") and enables to stack dies of different size e.g. several small dies on one big base die. Wafer-level packaging is packaging the dies while they are still on the wafer. Temporary bonding / debonding is an instrumental process that provides mechanical support for the wafers especially for 3
