Abstract: PURPOSE: A trench isolation method is provided to improve planarization of an isolating layer and overall planarization between the isolating layer and a semiconductor substrate, by etching an insulating material layer by a chemical mechanical polishing(CMP) process and a general wet or dry etching process. CONSTITUTION: After chemical mechanical polishing(CMP) blocking patterns(32) are formed on a semiconductor substrate(30), an anisotropical etching process is performed to form a trench(34a,34b) by using the CMP blocking patterns as a mask. An insulating material layer is applied as a shape for filling the trench while covering the CMP blocking patterns. The insulating material layer is firstly etched by a CMP process until the CMP blocking patterns starts to be exposed. The insulating material layer is secondly wet or dry etched until a predetermined thickness of the insulating material layer is left on the semiconductor substrate.
