  • Patent number: 6555462
    Abstract: A semiconductor device has a stress reducing laminate. Grooves are formed on the surface of a material layer selected from a multilayer structure of the semiconductor device, for example, a conductive layer. The cross sections of the grooves are semicircular or semi-elliptic. The stress applied to the conductive layer having the grooves is divided into a vertical component and a horizontal component with respect to the surface of the conductive layer. Accordingly, the stress applied vertically to the conductive layer is reduced, making it is possible to prevent the conductive layer from cracking due to stress and to reduce the stress transmitted to material layers under the conductive layer.

    Abstract: A method of fabricating a semiconductor device is provided that includes forming first and second gate electrodes on a substrate via a first photo mask, in which the first and second gate electrodes are in a longitudinal direction parallel to respective channels arranged in x-axis y-axis directions, measuring and comparing the lengths of the first and second gate electrodes on the substrate, estimating a mask bias on the basis of the difference between the actually measured lengths of the gate electrodes, and forming patterns of the first and second gate electrodes of which lengths are adjusted with the estimated mask bias on a new second photo mask, so that the first and second gate electrodes of the same length are formed on the same substrate via the new, second photo mask, regardless of the arrangement directions of the gate electrodes in parallel to channels. This has the effect of improving the processing speed of high CPU or logic element and the yield of products manufactured by this process.

  • Patent number: 6232189
    Abstract: A manufacturing method of semiconductor devices in which sources and drains define effective channels having lengths which are essentially equal to target length is disclosed. The method includes the steps of forming a gate electrode on a semiconductor substrate, measuring a length of the gate electrode, calculating a lateral diffusion distance using the measured length of the gate electrode and a length of a target effective channel, determining implantation conditions for forming a source and drain having the lateral diffusion distance, and forming the source and drain, by ion implanting in accordance with the implantation conditions. Even though the length of the gate electrode is changed in accordance with a change of the process conditions, sources and drains defining effective channels of a target length can be formed.
