Abstract
In a semiconductor device including a semiconductor body, a continuous oxide layer, a continuous metallization layer, and a diffusion zone, the diffusion zone is located below a portion of the continuous oxide layer to reduce this portion in thickness, and the corresponding part of the metallization layer in the region of the oxide layer portion of reduced thickness forms an undulation which protects the metallization layer against thermal stresses.
