Grains smaller than 350 nm were uniformly distributed when the [Cu] or the sintering temperature was low, but abnormal grain growth occurred as the sintering temperature or the [Cu] increased. As the area fraction of the abnormally grown grains decreased, the dielectric transition at T-C became more diffuse. The results were attributed to the internal stress model.
