    Abstract: PROBLEM TO BE SOLVED: To provide a microminiature spring contact suitable for probing of an active semiconductor device, and its manufacturing method. SOLUTION: A cantilever-shaped contact element 100 is long and narrow and has two ends 102, 104 and a center part 106 between the ends. The end 102 is a base part, and the contact element 100 is fitted with an electronic part (unillustrated) on the end 102. A coupling fixture 110 is provided on the base part 102. The coupling fixture 110 can be formed as a tab or a stud to facilitate brazing on a substrate at the assembly time. The end 104 is a free end, and a device to be tested is brought into contact with the end 104. An integrated projecting fixture 108, for example, in a pyramidal geometric shape, is provided on the tip 104 to assist connection by pressure to the terminal of the device to be tested. The contact element 100 has a step-shaped structure. The contact element can be easily manufactured by using a known lithography technology. COPYRIGHT: (C)2003,JPO
