In the PowerBase ECSEL project Siltronic acts as work package leader of WP2 Materials with the work for the tasks dealing with the development to establish a manufacturing process of 300 mm wafer in accordance with the requirements of the intended project partners to enable advanced power technologies on 300 mm silicon wafers.

Key Contribution:

The work package 2 encompasses the critical manufacturing step of crystal pulling targeting monocrystalline silicon ingots. One focus is ultra-low resistivity, the other very high resistivity in combination with low oxygen content. Thus as the key contribution novel 300 mm ultra-low resistivity silicon substrates for further reduced on-resistance as well as 300 mm high resistivity silicon substrates with low oxygen content for IGBT technology both resulting in cost efficient production is defined.
