An interconnect for testing semiconductor wafers, and a method and system for testing wafers using the interconnect are provided. The interconnect includes a substrate with contact members configured to establish temporary electrical communication with contact locations (e.g., bond pads, test pads) on the wafer. For flat contact locations (e.g., thin film bond pads), the contact members comprise raised members with penetrating projections. For bumped contact locations (e.g., solder bumps), the contact members comprise indentations with a conductive layer. The interconnect also includes a pressure sensing mechanism for monitoring and controlling contact forces between the interconnect and wafer. In an illustrative embodiment the pressure sensing mechanism comprises a piezoresistive or piezoelectric layer and resistance measuring device.
