DESCRIPTION:Graphene\, the 2D material with very promising mechanical and 
 electrical properties has now reached a level of maturity where an industr
 ial engagement is necessary on the way to commercialization.  Bosch the wo
 rldwide largest manufacturer of MEMS sensing devices is now a part of the 
 growing number of companies and startups looking into graphene application
 s and large scale fabrication routes for graphene synthesis.\nIn terms of 
 wafer based fabrication there is still a need for improvement of the commo
 nly used graphene synthesis process based on layer transfer techniques inc
 luding wet processing. An overview of possible methods and current progres
 s in this field will be covered in our presentation.\nIn terms of applicat
 ions Bosch corporate research has started first collaborations with the ac
 ademia to evaluate the potential of graphene for sensor applications. \nHe
 re\, Bosch currently focuses on magnetic sensing. The two-dimensional mate
 rial graphene exhibiting substantially higher charge carrier mobility seem
 s to be predestined for use in magnetic field sensing. Neglecting all extr
 insic sources of disorder\, the phonon scattering limited mobility of grap
 hene can surpass 100\,000 cm²/Vs at room temperature at a reasonably low 
 charge carrier density of 1012 cm-2\, exceeding all other common material 
 candidates for Hall sensing.\n
