First and second microelectronic elements (12), (14) can be affixed with packaging structure (30) therein. A first electrical connection (51A, 40A, 74A) can extend from a respective terminal (36A) of the package (10) to a corresponding contact (20A) on the first microelectronic element (12), and a second electrical connection (53A, 40B, 52A) can extend from the respective terminal (36A) to a corresponding contact (26A) on the second microelectronic element (14), the first and second connections being configured such that a respective signal carried by the first and second connections is subject to propagation delay of the same duration between the respective terminal (36A) and each of the corresponding contacts (20A, 26A) coupled thereto.
Abstract:
A microelectronic structure includes a first row of contacts (14) and a second row of contacts (24) offset from the first row, so that the first and second rows cooperatively define pairs of contacts. These pairs of contacts include first pairs (30a) and second pairs (30b) arranged in alternating sequence in the row direction. The first pairs are provided with low connectors (32a), whereas the second pairs are provided with high connectors (32b). The high connectors and low connectors have sections vertically offset from one another to reduce mutual impedance between adjacent connectors.
