A semiconductor processing method that can generate a hole with different diameters, comprising: providing first material and second material different from the first material; and utilizing a etching process to etch the first material and the second material to form a hole through the first material and the second material; wherein the etching process has different etching rates for the first material and the second material such that the hole have different diameters. A semiconductor structure corresponding to the above-mentioned method is also disclosed.
