摘要： A vertical PNP transistor and method for making it provide a transistor in a surface layer (12), which may be an epitaxial layer, of P- type conductivity at a surface of a substrate (11) of P+ type conductivity. An isolation region (14) of N- type conductivity in the P- surface layer (12) contains a collector region (25) of P- type conductivity. A base region (30) of N type conductivity is contained in the collector region (25), and an emitter region (40) of P+ type conductivity is contained in the base region (30). The base region (30) may be provided with a higher N type impurity concentration than a P type impurity concentration of the collector region (25). At least the collector region (25) and the base region (30) may be self aligned. The collector region (25) may be of thickness of about 2.2 .mu.m, the base region (30) of thickness of about 0.1 .mu.m, and the emitter region (40) of thickness of about 0.4 .mu.m. Although the transistor is vertically constructed, base and collector contacts (60 and 42-43) may be provided at a surface of the surface layer (12) opposite the substrate (11). A contact (62) may also be provided for the isolation layer (14) at the surface.

摘要： A semiconductor amplifier is provided comprising, a substrate and one or more unit amplifying cells (UACs) formed on the substrate, wherein each UAC is laterally surrounded by a first lateral dielectric filled trench (DFT) isolation wall extending at least to the substrate and multiple UACs are surrounded by a second lateral DFT isolation wall of similar depth outside the first isolation walls, and further semiconductor regions lying between the first isolation walls when two or more unit cells are present, and/or lying between the first and second isolation walls, are electrically floating with respect to the substrate. This reduces the parasitic capacitance of the amplifying cells and improves the power added efficiency. Excessive leakage between buried layer contacts when using high resistivity substrates is avoided by providing a further semiconductor layer of intermediate doping between the substrate and the buried layer contacts.
