    Abstract: A method of transporting substances in plasma streams to and depositing them on a target in which the vapors of two or more selected materials are turned into separate ionized plasmas in separate plasma generating chambers, the plasmas are effused from their respective chambers due to the difference in plasma density between the inside and outside of the chamber to form separate plasma streams and the plasma streams are joined to form a single stream which is conducted to the surface of a substrate by means of axial magnetic fields which also serve to converge the plasma streams. In another embodiment, a single stream is branched by a magnetic field to form plural streams which are conducted to different substrates or different points on the same substrate.

    Abstract: A method of forming a shallow P-N junction under precise control of its position. An impurity doped layer of the first conductivity type is formed, so that the impurity concentration may become a maximum at substantially the surface of a semiconductor substrate or at an inner part of the semiconductor substrate. Ions of impurities of a second conductivity type, opposite to the first conductivity type, are implanted, so that the impurity concentration may become a maximum greatest at the maximum depletion layer thickness in the semiconductor substrate. The P-N junction finally formed is located within the maximum depletion layer thickness.
