Abstract: A method for controlling an IC having logic cells and a clock-tree cell. Each logic cell has first and second FETs, which are pMOS and nMOS respectively. The clock-tree cell includes third and fourth FETs, which are pMOS and nMOS respectively. The clock-tree cell provides a clock signal to the logic cells.

The method includes applying first and second back gate potential difference (BGPD) to a logic cell's first and second FETs and either applying a third BGPD to a third FET, wherein the third BGPD is positive and greater than the first BGPD applied, which is applied concurrently, or applying a fourth BGEPD to a fourth FET, wherein the fourth BGPD is positive and greater than the second BGPD that is applied concurrently.

Abstract: The invention relates to a method for continuously manufacturing aligned nanostructures on a running support, which comprises conveying the support through a heated space and synthesising, in this space, aligned nanostructures on the support by catalytic chemical vapour deposition. The heated space is divided into n consecutive zones in the conveying direction of the support (n being an integer ?2), and the synthesis of the nanostructures results from heating and injection operations, in each of these n zones, of a flux of an aerosol containing a catalytic precursor and a source precursor of the material of the nanostructures to be formed, carried by a carrier gas. The injection operations are made by modifying, in at least two of the n zones, at least one parameter chosen among the flow rate of the carrier gas flux, the chemical composition of the carrier gas, the mass concentration of the catalytic precursor in the catalytic precursor and source precursor mixture.
