A test probe consists of an elongated screw machine contact biased by a helical spring and mounted in a through hole of a non-conductive substrate. One end of the contact includes a crown for engaging a solder ball lead of an IC package, and the contact includes an intermediate collar which maintains the contact within the through hole. The helical spring is disposed about the contact, with one end thereof engaging the lower end of the collar. The other end of the helical spring has contiguous coils and is of a reduced diameter so as to extend beyond the lower end of the non-conductive substrate to make electrical contact with a printed circuit board. When the test probe is compressed between the IC package and the printed circuit board, the inherent twisting of the helical spring causes the contact to tilt and make electrical contact with the contiguous coils, thereby establishing a direct electrical path between the IC package and the printed circuit board, with minimum resistance and minimum inductance. In an alternate embodiment, each probe is disposed within a dielectric housing which, in turn, is disposed in a through hole in a conductive substrate to effectively shield the probe from electrical interference.

An apparatus for testing semiconductor devices allows various testing processes, including a burn-in process, to be performed at the same testing stage.

The in-line system includes multiple test and burn-in apparatuses as well as a single sorting unit which performs a composite sorting operation after all the testing processes. A method for testing semiconductor devices in the in-line system includes testing the semiconductor devices in the test trays using the test and burn-in apparatus, transferring the test trays to a different testing apparatus for a second testing, and finally sorting the semiconductor devices after all testing processes have been performed based on a final sorting map created by combining test tray maps generated during each of the tests.

A test and burn-in apparatus for semiconductor chip package devices, an in-line system which includes the test and burn-in apparatus, and a test method which employs the in-line system are provided. A test and burn-in apparatus for testing semiconductor devices allows various testing processes, including a burn-in process, to be performed at the same testing stage. The apparatus employs test trays which contain the semiconductor devices. These test trays are used throughout the in-line system so that an entire back-end process can be performed without the need for loading / unloading the semiconductor devices into and from device trays between the various tests. The test and burn-in apparatus according to this invention can therefore occupy less space than the prior art testing apparatuses. The in-line system includes multiple test and burn-in apparatuses as well as a single sorting unit which performs a composite sorting operation after all the testing processes have been performed. Furthermore, the method for testing the semiconductor devices in the in-line system includes testing the semiconductor devices in the test trays using the test and burn-in apparatus, generating a test tray map corresponding to results of the test, transferring the test trays to a different testing apparatus for a second testing and test tray map generation process, and finally sorting the semiconductor devices in the sorting unit after all testing processes have been performed based on a final sorting map created by combining the test tray maps of each of the tests. The benefits of this invention are reduced time and space requirements because neither transferring the devices to device trays between tests nor performing multiple sorting steps are required.

A method for fabricating microelectronic spring structures is disclosed. In an initial step of the method, a layer of sacrificial material is formed over a substrate. Then, a contoured surface is developed in the sacrificial material, such as by molding the sacrificial material using a mold or stamp.

A layer of spring material is deposited over the contoured surface of the sacrificial material, in a pattern to define at least one spring form, and preferably an array of spring forms. The sacrificial material is then at least partially removed from beneath the spring form to reveal at least one freestanding spring structure. A separate conducting tip is optionally attached to each resulting spring structure, and each structure is optionally plated or covered with an additional layer or layers of material, as desired. An alternative method for making a resilient contact structure using the properties of a fluid meniscus is additionally disclosed. In an initial step of the alternative method, a layer of material is provided over a substrate. Then, a recess is developed in the material, and fluid is provided in the recess to form a meniscus. The fluid is cured or hardened to stabilize the contoured shape of the meniscus. The stabilized meniscus is then used to define a spring form in the same manner as the molded surface in the sacrificial material.

A probe pod housing is connected by a cable to an active probe. The probe pod housing carries a male push-on precision BNC connector that is also a cross-series adapter. The center conductor of the cable receives a male connector that then mates with the non-BNC end of the cross-series adapter. Auxiliary conductors that may also be carried by the cable are connected to male pins (soldered to a circuit board carried within the probe pod) with a push-on female in-line connector. The active probe itself uses a soldered-to-the-shield threaded nut technique. The nut threads into a metallic body that contains the impedance converter and that is enclosed by the body of the active probe. The cable is replaced by first unsoldering the center conductor (and also any auxiliary conductors). Then the nut (which is still soldered to the shield) is unscrewed from the metallic body, and the cable is free from the probe. At the probe pod end the cable mounted male connector is simply unscrewed from the cross-series adapter, and any auxiliary conductors disconnected by removing the female wire-mounted in-line connector.
