  • Patent number: 7465620
    Abstract: A method of improving the carrier mobility of a transistor is presented. A trench is formed in a substrate. The trench is filled with a dielectric. A CMOS transistor is formed adjacent to the trench. A silicide layer is formed on the source/drain region. After the step of forming the silicide layer, a recess is formed by etching the dielectric so that the surface of the dielectric is substantially lower than the surface of the substrate. Recessing the STI causes the removal of the compressive stress applied to the channel region by the STI material. A contact etch stop layer (CESL) is formed over the gate electrode, spacers, source/drain region and the dielectric. The CESL applies a desired stress to the channel region. Trench liners may optionally be formed to provide a stress to the channel region. A trench spacer may optionally be formed in the STI recess.

  • Patent number: 7462554
    Abstract: A method for forming a semiconductor device provides for forming a gate region on top of a substrate. Gate sidewall liners are formed on opposed sides of the gate region, the sidewall liners having a vertical part contacting sidewalls of the gate region and a horizontal part contacting the substrate. Recessed spacers are formed on top of the sidewall liners. The sidewall liner underneath the spacers is pulled back from the edge of the respective spacer by a predetermined distance. The recessed spacers are formed by reducing the height of the originally formed spacer. The height of the spacers is lower than a height of the gate sidewall liner and the width of the horizontal part of the sidewall liner is shorter than the width of the spacer. The reduced spacer height reduces device channel stress.

  • Patent number: 7312136
    Abstract: A method for making a SOI wafer with a strained silicon layer for increased electron and hole mobility is achieved. The method forms a porous silicon layer on a seed wafer. A H2 anneal is used to form a smooth surface on the porous silicon. A strain free (relaxed) epitaxial SixGe1-x layer is deposited and a bonding layer is formed. The seed wafer is then bonded to a handle wafer having an insulator on the surface. A spray etch is used to etch the porous Si layer resulting in a SOI handle wafer having portions of the porous Si layer on the relaxed SixGe1-x. The handle wafer is then annealed in H2 to convert the porous Si to a smooth strained Si layer on the relaxed SiGe layer of the SOI wafer.

  • Publication number: 20070235835
    Abstract: A semiconductor device provides a transistor adjacent an isolation trench. The device may be formed by producing isolation trenches in a semiconductor substrate, filling the trenches with a filler material, creating voids near top edges of the trenches and annealing by a gaseous ambient to reflow the edges of the trenches causing the edges to become rounded and overhang the trench. The filler material may be a dielectric. The transistors which are then formed in close proximity to the trenches may include source/drain regions formed in the rounded portion of the semiconductor substrate that overhangs the trench.
