There's substantial wafer capacity in the US, from silane production, through polysilicon granule production and wafer making. There are several different wafer makers in the US with both 200mm and 300mm wafer capacity.
Some of the silane and polysilicon companies are US owned, but I don't think that any of the wafer makers are US headquartered anymore.
