Abstract: The disclosed invention provides a method for the fabrication of a bipolar transistor having a collector region comprised within a semiconductor body separated from an overlying base region by one or more isolation cavities (e.g., air gaps) filled with low permittivity gas. In particular, a multilayer base-collector dielectric film is deposited over the collector region. A base region is formed onto the multilayer dielectric film and is patterned to form one or more base connection regions. The multilayer dielectric film is selectively etched during a plurality of isotropic etch processes to allow for the formation of one or more isolation region between the base connection regions and the collector region, wherein the one or more isolation regions comprise cavities filled with a gas having a low dielectric constant (e.g., air). The resultant bipolar transistor has a reduced base-collector capacitance, thereby allowing for improved frequency properties (e.g., higher maximum frequency operation).

Abstract: A method is provided to fabricate a bipolar transistor with a low base connection resistance, low defect density and improved scalability. Scalability is to be understood in this case as both the lateral scaling of the emitter window and the vertical scaling of the base width (low temperature budget). The temperature budget can be kept low in the base region since no implantations are required in order to reduce the base connection resistance. Furthermore, the difficulties associated with the point defects are largely avoided.

Abstract: For manufacturing a capacitor, in particular for a dynamic memory cell arrangement, a trench is etched in a substrate. In the trench, a layer sequence is produced that contains, in alternating fashion, layers of doped silicon and germanium-containing layers. By anisotropic etching, the surface of the semiconductor substrate (12) is exposed in the region of the trench floor. The trenches are filled with a conductive support structure (20). The germanium-containing layers are removed selectively to the layers of doped silicon. The exposed surface of the layers of doped silicon (17) and of the support structure (20) are provided with a capacitor dielectric (22), onto which is applied a counter-electrode (23).

The nuclei can be employed both as a mask, for example, when etching or implanting, as will as active or passive component parts that remain in the structure, for example, as charge storages in the dielectric of an EEPROM.

Abstract: In producing a CMOS circuit, an n-channel MOS transistor and a p-channel MOS transistor are formed in a semiconductor substrate. In situ p-doped, monocrystalline silicon structures are formed by epitaxial growth selectively with respect to insulating material and with respect to n-doped silicon, such silicon structures being suitable as a diffusion source for forming source/drain regions of the p-channel MOS transistor. The source/drain regions of the n-channel MOS transistor are produced beforehand by means of implantation or diffusion. Owing to the selectivity of the epitaxy that is used, it is not necessary to cover the n-doped source/drain regions of the n-channel MOS transistor during the production of the p-channel MOS transistor.
