Publication number: 20130002272Abstract: A test circuit and method for testing through-silicon-vias (TSVs) in three-dimensional integrated circuits (ICs) during each phase of manufacturing is disclosed. In one aspect, the method includes testing for faults in each individual TSV, TSV-under-test, shorts between a TSV-under-test, and TSVs in close proximity and for connections between the TSV-under-test and another tier in the ICs. A test circuit has three switchable current paths connected to a power supply via a pull-up resistor and switches: a calibration path, a short path, and a current measurement path. A power supply is connected to the measurement path, and the calibration path and the short path are connected to ground via respective pull-down resistors. For each TSV-under-test, the desired operation mode is selected by the closure of different combinations of switches. The current flowing through the pull-up resistor in each operation mode indicates whether the TSV-under-test has passed or failed the test.Type: ApplicationFiled: June 30, 2011Publication date: January 3, 2013Applicant: IMECInventors: Mustafa Badaroglu, Erik Jan Marinissen, Paul Marchal

Publication number: 20120298961Abstract: A method to fabricate a hetero-junction in a Tunnel Field Effect Transistor device configuration (e.g. in a segmented nanowire TFET) is provided. A thin transition layer is inserted in between the source region and channel region such that the out-diffusion is within a very limited region of a few nm, guaranteeing extremely good doping abruptness thanks to the lower diffusion of the dopants in the transition layer. The transition layer avoids the direct contact between the highly doped source region and the lowly doped or undoped channel and allows to contain the whole doping entirely within the source region and transition layer. The thickness of the transition layer can be engineered such that the transition layer coincides with the steep transition step from the highly doped source region to the intrinsic region (channel), and hence maximizing the tunneling current.Type: ApplicationFiled: July 25, 2012Publication date: November 29, 2012Applicant: IMECInventors: Francesca Iacopi, Anne S.
