Abstract
There is provided a method for the manufacture of an integrated circuit, including a substrate and an insulating layer formed on the substrate; a first pMOS transistor formed on the insulating layer and including a channel formed in a first layer of a silicon—germanium alloy, having a first thickness and first average germanium density; a gate oxide layer having a first equivalent oxide thickness; a second pMOS transistor formed on the insulating layer and further including a channel formed in a second layer of a silicon—germanium alloy, having a second thickness which is greater than the first and a second average germanium density which is lower than the first; and a gate oxide layer having a second equivalent oxide thickness which is greater than the first.
