    摘要: Provided is a method of forming a stress-relaxed SiGe buffer layer on a silicon substrate using a reduced pressure chemical vapor deposition (RPCVD) technique. The method includes: forming a graded composition layer having a predetermined germanium composition gradient on a silicon substrate; forming and thermally annealing a first constant composition layer having a predetermined germanium composition on the graded composition layer; removing the first constant composition layer by a predetermined thickness to planarize a surface; and forming a second constant composition layer on the first constant composition layer to form a SiGe buffer layer having the graded composition layer and the constant composition layer. A strained silicon or SiGe channel can be formed in a silicon-based MOSFET device or a MODFET device by forming the stress-relaxed SiGe buffer layer that has a relatively thin thickness, a low surface dislocation density, and a surface roughness similar to bulk silicon, and thus a device having excellent channel conductivity and high frequency characteristics can be manufactured.

    摘要: Provided is a method of fabricating a silicon germanium (SiGe) Bi-CMOS device. In the fabrication method, the source and drain of the CMOS device is formed using a silicon germanium (SiGe) heterojunction, instead of silicon, thereby preventing a leakage current resulting from a parasitic bipolar operation. Further, since the source and drain is connected with an external interconnection through the nickel (Ni) silicide layer, the contact resistance is reduced, thereby preventing loss of a necessary voltage for a device operation and accordingly, making it possible to enable a low voltage and low power operation and securing a broad operation region even in a low voltage operation of an analogue circuit.

    摘要: The present invention relates to an improved pillar anchor and a method for manufacturing the same. According to the pillar anchor of the present invention described as above and the method for manufacturing the same, the rims of the pair of separated base plates abut each other, so that the surface in contact with the belt is formed in a “C”-shape. Thus, it is simple to manufacture the pillar anchor of the present invention, and moreover, the number of processes needed for manufacture is reduced. In addition, since the inner peripheral surfaces of the belt insertion holes around which the belt is wound are generally formed of only a steel plate, the friction coefficient between the belt and the inner peripheral surfaces of the belt insertion holes is reduced. Accordingly, when the belt is subjected to tension, damage caused from wear and tear of the belt due to the friction between the belt and the inner peripheral surfaces of the belt insertion holes is effectively reduced. Moreover, the belt can smoothly moves on the inner peripheral surfaces of the belt insertion holes.
