  • Publication number: 20240170298
    Abstract: A method to produce an integrated circuit including depositing a first layer of a metallic chemical constituent on a silicon substrate. A protective layer including a main chemical constituent different from the main chemical constituent of the first layer is then deposited on this first layer. An additional layer is deposited on the protective layer and includes a main chemical constituent different from, equivalent to or of equivalent size to the main chemical constituent of the first layer. A heat treatment operation is carried out at a first temperature to generate a silicide including the main constituent of the first layer and silicon according to a first stoichiometry. In a subsequent step, the additional layer and the protective layer are removed. In another step, a further heat treatment operation is carried out at a temperature greater than the first temperature in order to change the stoichiometry of the previously created silicide.
