Abstract

A microelectronic unit can include a semiconductor element having a front surface, a microelectronic semiconductor device adjacent to the front surface, contacts at the front surface and a rear surface remote from the front surface. The semiconductor element can have through holes extending from the rear surface through the semiconductor element and through the contacts. A dielectric layer can line the through holes. A conductive layer may overlie the dielectric layer within the through holes. The conductive layer can conductively interconnect the contacts with unit contacts.
