A method of making an anisotropic conductive element for use in microelectronic packaging includes providing a layer of material having a pair of oppositely-directed major faces, the layer incorporating a curable dielectric material in a fluid condition and electrically conductive particles in the curable dielectric material and applying a magnetic field to the layer of a material so as to alter the configuration of the particles and so as to form areas of high particle concentration defining a plurality of conductive paths extending between the major faces of the layer of a material. After applying the magnetic field, the dielectric material is cured.

In certain embodiments, at last some of the conductive particles are elongated so that when the magnetic field is applied to the layer of a material, the magnetic field turns the axes of elongation of at least some of the elongated particles towards the vertical direction. In other embodiments, the magnetic field moves at least some of the conductive particles in horizontal directions.

A sample is rotated about an axis perpendicular to a surface of the sample in predetermined angular steps. The surface of the sample is irradiated with linearly polarized light, and a reflected intensity of light reflected from the surface of the sample is detected in each angular step. Based on a rotational angle dependency of the reflected intensity, the crystal face orientation of the sample is determined. To improve signal-to-noise ratio, the crystal lattice of the sample is excited. Further, the surface of the sample is irradiated with a plurality of linearly polarized light beams to obtain a plurality of reflected intensities.

A connector for microelectronic elements includes a sheetlike dielectric layer having a plurality of through holes desirably arranged in a rectangular grid pattern. Each hole is provided on one major surface with a generally laminar contact having at least one projection extending inwardly over the through hole. Contact pads on the second major surface of the dielectric layer overlie the through holes to provide a blind end which is electrically connected to the other contact by means of a metal layer lining the through hole. The resulting connectors provide low or zero insertion force sockets for mounting microelectronic elements having bump leads thereto. The bump leads may be received within corresponding sockets without engagement with the contact or projection, and then, by movement in a lateral direction, engaging the contact or projection to provide electrical connection to the socket.
