Abstract

There is disclosed an option function test apparatus of a semiconductor device including a function selecting means. The function selection means includes a fuse signal detecting section for sensing the state of fuse blowing, a pad signal detecting section for sensing the signal state on the probe pad for selecting its specification, which is consisted by incorporating extra probe chips into the existing probe card, and a global signal control section for receiving the output signals from said fuse signal detecting section and said pad signal detecting section to output different output signals based on its operation mode. Thus, the present invention can provide an outstanding effect of reducing additional test time and cost depending on the changes in function, since it allows a multifunction test of all of the specifications mounted on the on-chip in a wafer state.
