Abstract:
An apparatus for testing semiconductor integrated circuits comprising:a box-shaped main frame housing therein an IC tester part conducting an electrical test on a semiconductor integrated circuit under test;a testing head including contact means connected through a cable to said IC tester part, said contact means being supported on the testing head in the state that said contact means is exposed on one face of said testing head, said testing head being movable between a first position where the one face of said testing head on which said contact means is exposed faces downward and a second position where said one face of said testing head faces upward;drive means for moving said testing head between said first and second positions; anda wafer prober disposed adjacent to said main frame and including on a top face thereof a contact section contacting with the contact means of said testing head when the testing head is moved to said first position by said drive means,said contact section of said wafer prober being contacted with terminals of a semiconductor integrated circuit to be tested which is supplied to the contact section, thereby enabling the testing of the semiconductor integrated circuit by said IC tester part, whereinsaid testing head is above a top of said main frame in such a state that the one face of said testing head on which said contact means is exposed faces upward when the testing head is moved to the second position by said drive means.
