发明名称 Semiconductor device having a connection inspecting circuit for inspecting connections of power source terminals and grounding terminals, and inspection method for the same
摘要 The invention provides a semiconductor device that can inspect the connection states of power source terminals and grounding terminals of a test LSI at a low cost and in a short time, and an inspection method for the same. Switches SW 1 to SW 3 are provided between a plurality of power source terminals PD 1 to PD 3 and a power source line 10 inside the test LSI 4 . A switch SWT is provided between the power source line and a grounding line 11 inside the test LSI. When inspecting the connection state of a certain power source terminal, the switch connected between the power source terminal and the power source line is closed, the switch SWT between the power source line and the grounding line is closed, and remaining switches are opened. A voltage is supplied between the power source terminal and a grounding terminal, and whether or not the power source terminal is in the connected state is determined by whether or not a current flows.
