    Abstract: A method of processing a semiconductor device shapes a layer buried within a substrate of the semiconductor device. This layer has a conductivity the same as that of the substrate but has a higher doping level. In this process, a region of the layer is selected and ions of an opposite conductivity to the selected layer are counter-implanted in the region so that the doping level is substantially canceled. A region of the layer adjacent to the counter-implanted region retains a higher doping level. Alternative techniques are employed to protect the doped region against the counter-implant. In a first approach, the layer is doped and subsequently a mask is formed on the surface of the substrate. The mask is furnished by a part of the semiconductor device, such as a spacer which is connected to the gate electrode after the dopant layer is formed in the substrate. After the mask is formed, ions are counter-implanted with the mask protecting the doped region. In a second approach, both the ion implant forming the doped layer and the counter-implant are performed after masking structures are formed, however the ion implant is a large-angle implant which implants ions beneath the masking structure while the counter-implant is a perpendicular implant so that regions beneath the masking structure are protected from cancellation.

    Abstract: The invention includes a semiconductor construction having a pair of channel regions that have sub-regions doped with indium and surrounded by boron. A pair of transistor constructions are located over the channel regions and are separated by an isolation region. The transistors have gates that are wider than the underlying sub-regions. The invention also includes a semiconductor construction that has transistor constructions with insulative spacers along gate sidewalls. Each transistor construction is between a pair source/drain regions that extend beneath the spacers. A source/drain extension extends the source/drain region farther beneath the transistor constructions on only one side of each of the transistor constructions. The invention also includes methods of forming semiconductor constructions.

    Abstract: A method for producing MOS transistors of the type having shallow, lightly doped, source/drain structure. In this method sidewall fillets (7) of n-type doped dielectric material are defined adjacent to the sides of the oxide (1) and metal electrode (3) features. These fillets (7) are then employed to provide self aligned masking during implantation of heavy dopant of either n- or p-type (9; 13). In a subsequent rapid anneal step, the implant dopant is activated and n-type dopant diffused into the substrate (5) from the fillets (7) to provide lightly doped source/drain structures (11; 15). Examples of this method are described for producing phosphorous-arsenic n /n and phosphorus-boron p /p source/drain structures.

    Abstract: In semiconductor devices of extremely small dimensions, the problem of shorting together of adjacent, differently doped regions (12, 14) by a contact layer deposited through a window (17) which, owing to the smallness of the region dimensions, unavoidably exposes a surface portion of the adjacent region (12) not intended to be contacted, is solved by the use of a transfer layer (18) deposited first in the window which, upon heating, transfers impurities from the region (14) intended to be contacted to the unintentionally exposed portion of the adjacent region (12). The transferred impurities convert the exposed portion of the adjacent region to the same conductivity type as the impurity source region (14), thereby preventing shorting together of the contacted region (14) with the remaining, unconverted portion of the adjacent region.

    Abstract: An epitaxial layer with a doping of approximately 10 atoms per cm is used in accordance with the resurf condition for the high-voltage circuit element in high-voltage integrated circuits of the resurf type. If the circuit comprises a zone which is provided in the epitaxial layer, which is of the same conductivity type as the substrate, and to which a high voltage is applied, the doping between this zone and the substrate must in addition be sufficiently high for preventing punch-through between the zone and the substrate. A known method of complying with these two requirements is to make the epitaxial layer very thick. It is found in practice, however, that this method is often not very well reproducible. According to the invention, the epitaxial layer is provided in the form of a high-ohmic layer which is doped from the upper side (3a) and from a buried layer (3b). The buried layer is blanket-deposited, which dispenses with a masking step, and is locally redoped by the island insulation zone (4).
