Structures and methods for directly testing a semiconductor wafer having micro-solder connections. According to one embodiment, a method forms a pattern of micro-solder connections coupled with a through substrate via (TSV) that can be directly tested by electrical probing, without the use of a testing interposer. According to another embodiment, a method tests the pattern of micro-solder connections. According to another embodiment, a novel electrical probe tip structure has contacts on the same pitch as the pattern of micro-solder connections.
