Abstract

Packaging is an indispensable part in microelectronics manufacturing industry, where transfer molding as an essential step is typically included for encapsulation. Recently, with the fruitful achievements of research on graphene in gas sensing, there is also urgent need for study on how the packaging process will affect the graphene, to develop compatible manufacture protocol for practical graphene-based gas sensor. In this work, we carried out experiments on how molding compound outgassing affects graphene for gas sensing. Our results show that although there is some impact on the electrical properties of the graphene, there is no change in the microstructure, and only a slight and manageable change in gas sensing abilities. This work suggests that graphene could maintain performances after epoxy molding packaging processes.
