    Abstract: PROBLEM TO BE SOLVED: To provide a gate structure for MOSFETs for application of the CMOS technology, etc., which is durable against high temperature processes such as junction activation, etc., and reduces the gate propagation delay. SOLUTION: The gate structure 10 has an insulation layer 14 on a semiconductor substrate 12, and a polysilicon gate electrode 16 on the insulation layer 14. The gate structure 10 comprises a diffused barrier layer 20 having semi- insulative characteristics on the gate electrode 16, and a gate conductor 18 on the barrier layer 20. The conductor 18 is electrically contacted to the gate electrode 16. The constitution and the thickness of the barrier layer 20 are adjusted so as to effectively block the diffusion and the mixing between the gate conductor 18 and the gate electrode 16, but realize a capacitive coupling and/or a leak current not so increasing the gate propagation delayer of the gate surface 10.

    Abstract: Disclosed is an improved semiconductor structure 150 (e.g., a silicon germanium (SiGe) hetero-junction bipolar transistor 100) having a narrow essentially interstitial-free SIC pedestal 120 with minimal overlap of the extrinsic base 104. Also, disclosed is a method of forming the transistor which uses laser annealing, as opposed to rapid thermal annealing, of the SIC pedestal to produce both a narrow SIC pedestal and an essentially interstitial-free collector. Thus, the resulting SiGe HBT transistor can be produced with narrower base 103 and collector space-charge regions than can be achieved with conventional technology.

    Abstract: Expitaxial substitutional solid solutions of silicon carbon (101 ) can be obtained by an ultra-fast anneal of an amorphous carbon-containing silicon material. The anneal is performed at a temperature above the recrystallization point, but below the melting point of the material and preferably lasts for less than 100 milliseconds in this temperature regime. The anneal is preferably a flash anneal or laser anneal. This approach is able to produce epitaxial silicon and carbon-containing materials (101 ) with a substantial portion of the carbon atoms at substitutional lattice positions. The approach is especially useful in CMOS processes and other electronic device manufacture where the presence of epitaxial Si1-yCy, y
