Abstract: PURPOSE: A CMP(chemical mechanical polishing) process for separating a self-aligned contact pad is provided to set a precise time interval of a CMP process even in a variation of a step between adjacent gate stacks due to an etch process for forming a self-aligned contact hole by correcting the CMP time interval by a relational expression established by using a semiconductor wafer having a test pattern for a test. CONSTITUTION: A relational expression among the first step between the first and second test patterns before a planarization process, the second step between the first and second test patterns after the planarization process, and a separation degree of a self-aligned contact pad is established(310). The first step with respect to a semiconductor device to planarize is measured(320). By referring to the relational expression, a proper interval of planarization time corresponding to the first step is presumed(330). During the presumption time, a planarization process is performed on the semiconductor substrate(340), and the second step is measured(350). By referring to the relational expression, the separation degree of the self-aligned contact pad corresponding to the measured second step is compared with a reference value(360). The planarization time is corrected to sufficiently separate the self-aligned contact pad so as to be used in the next semiconductor device.
