Title:
シリコン単結晶基板中に、MOSFETデバイスのための接合を形成するための方法
Document Type and Number:
Japanese Patent JP4948785
Kind Code:
B2
Abstract:
A structure and method of fabrication for MOSFET devices with a polycrystalline SiGe junction is disclosed. Ge is selectively grown on Si while Si is selectively grown on Ge. Alternating depositions of Ge and Si layers yield the SiGe junction. The deposited layers are doped, and subsequently the dopants outdiffused into the device body. A thin porous oxide layer between the polycrystalline Ge and Si layers enhances the isotropy of the SiGe junctions.
