A microelectronic package can include a substrate having a first surface and a plurality of substrate contacts at the first surface and a microelectronic element having a front surface and contacts arranged within a contact-bearing region of the front surface. The contacts of the microelectronic element can face the substrate contacts and can be joined thereto. An underfill can be disposed between the substrate first surface and the contact-bearing region of the front surface of the microelectronic element. The underfill can reinforce the joints between the contacts and the substrate contacts. A joining material can bond the substrate first surface with the front surface of the microelectronic element. The joining material can have a Young's modulus less than 75% of a Young's modulus of the underfill.

A coupling element for providing external coupling to a semiconductor die within an integrated circuit package. The coupling element comprises a flexible laminate structure comprising a flexible, electrically insulating substrate layer, a first conductive layer bonded to a first surface of the substrate layer, and a second conductive layer bonded to a second surface of the substrate layer. The coupling element is arranged to be coupled to the semiconductor die such that the first and second conductive layers are electrically coupled to electrical contacts of the semiconductor die. The coupling element is further arranged to extend through the integrated circuit package when electrically coupled to the semiconductor die, and for the first and second conductive layers to be further electrically coupled to at least one external component.

A method of fabricating a microelectronic package can include mounting a microelectronic element to a substrate with a joining material. The mounting can include bonding a front surface of the microelectronic element to a first surface of the substrate with a joining material, and joining contacts arranged within a contact-bearing region of the front surface of the microelectronic element with corresponding substrate contacts at the substrate first surface, the joining creating electrical contact between the microelectronic element and the substrate. The method can also include forming an underfill between the substrate first surface and the contact-bearing region of the front surface of the microelectronic element, the underfill reinforcing the joints between the contacts and the substrate contacts, the joining material having a Young's modulus less than 75% of a Young's modulus of the underfill.
