Anodic wafer bonding involves encapsulating components on the wafer by means of ionic glass. In triple-stack bonding, three layers (i.e. glass-silicon-glass) are simultaneously bonded, enhancing both functionality and yield.
Eutectic wafer bonding takes advantage of the special properties of eutectic metals. Similar to soldering alloys, such metals melt already at low temperatures. This property allows planar surfaces to be achieved.
In order to control reflow of the eutectic material, eutectic bonding requires precise dosing of the bonding force and even temperature distribution.
Fusion bonding refers to spontaneous adhesion of two planar substrates. The process involves rinsing the polished discs and rendering them largely hydrophilic, then placing them in contact and tempering them at high temperatures. Plasma pretreatment allows the substrates to be bonded at room temperature.
Glass Frit Bonding
A glass frit bonding process involves screen-printing glass frits onto the bonding surfaces. This results in structures that are subsequently heated and fused when the two substrate surfaces are placed in contact. On cooling, a mechanically stable bond results.
To minimize the risks in thin wafer handling, the wafer is mounted on a carrier wafer prior to thinning. Bonding is only to facilitate further processing – the bond is designed to be dissolved once the wafer is processed.
Process steps required for temporary wafer bonding
SUSS MicroTec offers an open platform that is compatible with all common material systems used in temporary wafer bonding. In addition to the methods already used in production today, SUSS MicroTec is devoted to ongoing work towards qualifying new materials, in this way supporting the largest selection of adhesives currently available in the market.
