No, this is panels from which interposers will be made. Which are now larger than chips and rectangular, so wasted edges from a 300mm wafer are high. The proposed size is much larger than chip-grade ingots. They don't need perfect silicon. It can be grown on a continuous ribbon which is sliced into panel sizes like they do for solar cells. If they need a perfect surface they can deposit some pure Si to finish it. Maybe we will eventually see that replace ingots for chip grade.
