Abstract

We propose an electrical test method of resistive and capacitive open defects occurring at data bus lines between dies, and between dies and I/O pins in 3D memory ICs. The test method is based on supply current of an IC. The number of test vectors for a 3D memory IC made of ND memory dies in the test method is 10∙ND and small. Also, defective interconnects are located by the test method. Feasibility of the tests is examined by some experiments for a circuit made of an SRAM IC on a printed circuit board. The experimental results show that capacitive open defects and resistive open ones whose resistance values are greater than 200Ω can be detected by the test method.
