Abstract
Provided is a ceramic substrate. The ceramic substrate includes a core layer, made of zirconia toughened alumina; and surface layers, symmetrically located on an upper and a lower surfaces of the core layer, made of AlO. The core layer has a chemical composition of 0 wt %<ZrO≤40 wt % and 60 wt %≤AlO<100 wt %. A method for manufacturing the ceramic substrate and a power module including the ceramic substrate are also provided.
