Abstract: The article deals with a novel laboratory anodic bonding device. This device is used for MEMS creation. The anodic bonding is a method for joining glass with silicon. It is one of the important steps of MEMS components packaging. The bonding mechanism joins the glass and silicon by heating them above 400 °C.

The rate processes which occur during anodic bonding are modeled using data from various studies. For a given mate- rials system, the process occurs at constant total charge transfer. The observed activation energies are consistent with dc conduction in the glass. The charge transfer required for bonding to aluminum.
