A method of physically connecting two chips to each other includes aligning an electrically conductive contact of a first chip with a corresponding electrically conductive contact on a second chip, the electrically conductive contact of the first chip being a rigid material, The electrically conductive contact of the material is a flexible material for a rigid material; Contacting the aligned electrically conductive contacts of the first chip to corresponding electrically conductive contacts on the second chip; The contact of the first and second chips is raised to a temperature at least below the liquefaction temperature of the rigid material while applying sufficient pressure to the first and second chips to allow the rigid material to penetrate the malleable material and form an electrically conductive connection therebetween step; And cooling the contacts of the first and second chips to ambient temperature after formation of the electrically conductive connection.n n n n Electrically conductive contacts, chips, rigid materials |
