    摘要: A microelectronic assembly includes a first microelectronic element having a contact bearing face and at least one contact accessible at the contact bearing face, and a second microelectronic element opposing the first microelectronic element, the second microelectronic element having a first surface including at least one lead extending over the first surface. The microelectronic assembly includes the first fusible material engaging the at least one contact of the first microelectronic element, and a second fusible material engaging the at least one lead, whereby one of the first and second fusible materials has a higher melting temperature and one of the first and second fusible materials has a lower melting temperature. The first and second microelectronic elements are juxtaposed with one another so that the first and second fusible materials are in substantial alignment with one another, with one of the first and second fusible materials in a liquid state and one of the first and second fusible materials in a solid state.

    摘要: A method of making a microelectronic assembly includes providing a first microelectronic element having one or more conductive bumps, the conductive bumps including a first fusible material that transforms from a solid to a liquid at a first melting temperature, and providing a second microelectronic element having one or more conductive elements. The conductive bumps of the first microelectronic element are electrically interconnected with the conductive elements of the second microelectronic element using a second fusible material, the second fusible material having a second melting temperature that is lower than the first melting temperature of the first fusible material. During the electrically interconnecting step, the second fusible material is maintained at a temperature that is greater than or equal to the second melting temperature and less than the first melting temperature of the first fusible material. The method also includes testing the microelectronic assembly after the electrically interconnecting step while maintaining the second fusible material at a temperature that is greater than or equal to the second melting temperature.

    摘要: A method of preparing hydrogel particles includes applying a solution including a plurality of hydrogel particles to a stir cell. A retentate side of a filter defines a lower surface of the stir cell. The filter has the retentate side and a permeate side. The method further includes, while stirring the solution within the stir cell, dispensing a buffer solution at a first flow rate to the stir cell and drawing a permeate from the permeate side of the filter using a pump at a second flow rate, the permeate including a subset of the plurality of hydrogel particles.

    摘要: The invention provides particle compositions having applications in nucleic acid analysis. Nucleic acid polymer particles of the invention allow polynucleotides to be attached throughout their volumes for higher loading capacities than those achievable solely with surface attachment. In one aspect, nucleic acid polymer particles of the invention comprise polyacrylamide particles with uniform size distributions having low coefficients of variations, which result in reduced particle-to-particle variation in analytical assays. Such particle compositions are used in various amplification reactions to make amplicon libraries from nucleic acid fragment libraries.
