    Abstract: A test structure includes a single current-measuring means for measuring current between a supply terminal and ground, and first and second branches for measuring capacitance between first and second metal lines. The first branch includes a first switch coupled between the current-measuring means and the first line, and a second switch coupled between the first line and ground. Similarly, the second branch includes a third switch coupled between the current-measuring means and the second line, and a fourth switch coupled between the second line and ground. A method for testing a circuit is also provided. According to the method, the capacitance between first and second metal lines is calculated by: measuring a first current needed to bring the first line to the voltage of a first terminal while the other lines are at the voltage of a second terminal, measuring a second current needed to bring the second line to the voltage of the first terminal while the other lines are at the voltage of the second terminal, and measuring a third current needed to bring the first and second lines to the voltage of the first terminal while the other lines are at the voltage of the second terminal. The measurements are performed using a single current-measuring means.

    Abstract: An MOS transistor with a fully silicided gate is produced by forming a silicide compound in the gate separately and independently of silicide portions located in source and drain zones of the transistor. To this end, the silicide portions of the source and drain zones are covered by substantially impermeable coatings. The coatings prevent the silicide portions of the source and drain zones from increasing in volume during separate and independent formation of the gate silicide compound. The silicide gate may thus be thicker than the silicide portions of the source and drain zones.

    Abstract: A semiconductor material is protected against the formation of a metal silicide by forming a layer of a silicon/germanium alloy on the material. The material which is protected belongs to a component of an integrated circuit comprising other components that have to be subjected to a siliciding operation. The method of protection includes depositing a layer of silicon/germanium alloy on the integrated circuit. The layer of silicon/germanium alloy is then removed from the areas to be silicided. A metal is then deposited on the structure and a metal silicide is formed therefrom. The unreacted metal and the metal/silicon/germanium ternary alloy that may have formed are removed, and the layer of silicon/germanium alloy is removed so as to expose the unsilicided component.

    Abstract: A device includes a capacitive structure including an input node and n output nodes, r integrated capacitors connected in series between two adjacent nodes, an integrated capacitor connected between the input node and ground, an integrated capacitor connected between the nth output node and ground, and r capacitive branches connected in parallel between ground and each node of the capacitive structure including the first output node and the (n−1)th output node. Each branch may include r+1 series-connected integrated capacitors. Furthermore, the integrated capacitors of the capacitive structure are theoretically identical. The device may also include a charge source for charging each node of the capacitive structure. Additionally, a measurement circuit may measure the charge at each of the nodes of the structure, and a comparison circuit may compare each measured nodal charge value with a theoretical nodal charge value while taking into account a predetermined nodal tolerance.
