The attenuation function of the isolationtrench to the shock vibration is more effective with increase in the intensity of the blast loading.
隔振沟对振动加速度的衰减作用随载荷强度的增加而增强。

For devices formed on an oxide isolation layer, the poly - filled trench desirably penetrates this isolation layer thereby improving thermal conduction from the active regions to the substrate.
