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

PROBLEM TO BE SOLVED: To provide a microelectronic contact structure and its manufacturing method. SOLUTION: The method for mounting two or more spring contact elements to the terminals of an electronic component includes fabricating the two or more spring contact elements on a sacrificial substrate, then mounting the parts of the spring contact elements to the terminals of the electronic component while the spring contact elements are on the sacrificial substrate, and removing the sacrificial substrate after the parts of the spring contact elements are mounted to the terminals of the electronic component.

PROBLEM TO BE SOLVED: To provide a microelectronic contact structure and a manufacturing method for manufacturing the microelectronic contact structure. SOLUTION: The method for mounting a plurality of spring contact elements to the terminal of an electronic component includes the manufacture of a plurality of spring contact elements on a sacrifice substrate, mounting one portion of the spring contact elements to the terminal of electronic components while the spring contact element is on the sacrifice substrate, and the removal of the sacrifice substrate after one portion of the spring contact element is mounted to the terminal of the electronic components.

Abstract:
PROBLEM TO BE SOLVED: To provide a microelectronic contact structure and a method of making the same. SOLUTION: A device includes an electronic component including a trench in a surface, a terminal disposed on the surface of the electronic component and spaced from the trench, and an elongate spring contact element. The elongate spring contact element has a base portion affixed to the terminal, a body portion spaced above the surface of the electronic component and extended across the trench, and a contact portion spaced above the trench. The contact portion is movable toward the trench, and the spring contact element has a first spring constant. When the contact portion is moved enough toward the trench, the body portion contacts the end located between the surface and the trench, and when the contact portion is moved further toward the trench, the spring contact element exhibits a second spring constant different from the first spring constant.

Abstract:
The contact provides a micro-miniature spring contact for mounting active semiconductor devices. The structure comprises a resilient spring contact (100) with one end (102) being a base end which is mounted to an electronic component. The other end (104) is a "free end" tip which provides a pressure connection to another electronic component. The structure is steeped with the base end at one height and with the free end at second height. There is a central portion (106) between the two end portions and which is at a third height. Thus there are two steps in the structure which performs as a cantilever beam.
Abstract:
Interconnection elements (550) for electronic components (556), exhibiting desirable mechanical characteristics (such as resiliency), for making pressure contact(s) are formed by shaping a ribbon-like core element (552) of a soft material (such as gold or soft copper) to have a springable shape (including cantilever beam, S-shape, U-shape), and overcoating the shaped core element with a hard material (558) such as nickel and it alloys, to impart a desired spring (resilient) characteristic to the resulting composite interconnection element (550). A final overcoat of a material (220) having superior electrical qualities (e.g., electrical conductivity and/or solderability) may be applied to the composite interconnection element (200). The resulting interconnection elements (500, 550) may be mounted to a variety of electronic components.
