  • 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.

  • Patent number: 7238989
    Abstract: A method of fabricating a CMOS device wherein mobility enhancement of both the NMOS and PMOS elements is realized via strain induced band structure modification, has been developed. The NMOS element is formed featuring a silicon channel region under biaxial strain while the PMOS element is simultaneously formed featuring a SiGe channel region under biaxial compressive strain. A novel process sequence allowing formation of a thicker silicon layer overlying a SiGe layer, allows the NMOS channel region to exist in the silicon layer overlying a SiGe layer, allows the NMOS channel region to exist in the silicon layer which is under biaxial tensile strain enhancing electron mobility. The same novel process sequence results in the presence of a thinner silicon layer, overlying the same SiGe layer in the PMOS region, allowing the PMOS channel region to exist in the biaxial compressively strained SiGe layer, resulting in hole mobility enhancement.
