Abstract:
Gate electrodes of an N-channel transistor and a P-channel transistor are formed on a semiconductor substrate with a gate insulator therebetween. After conducting a first thermal treatment to the gate electrodes, N-type heavily doped diffusion layers to be a source or a drain of the N-channel transistor are formed using the gate electrode of the N-channel transistor as a mask. After conducting a second thermal treatment to the N-type heavily doped diffusion layers at a lower temperature than that of the first thermal treatment, P-type heavily doped diffusion layers to be a source or a drain of the P-channel transistor are formed using the gate electrode of the P-channel transistor as a mask. Then, a third thermal treatment is conducted to the P-type heavily doped diffusion layers at a lower temperature than that of the second thermal treatment.

Abstract:
Disclosed is a semiconductor device using a polycrystalline compound semiconductor with a low resistance as a low resistance layer, and its fabrication method. The above polycrystalline compound semiconductor layer is doped with C or Be as impurities in a large amount, and is extremely low in resistance. The polycrystalline compound semiconductor layer is formed by either of a molecular beam epitaxy method, an organometallic vapor phase epitaxy method and an organometallic molecular beam epitaxy method under the condition that a substrate temperature is 450.degree. C. or less and the ratio of partial pressure of a V-group element to a III-group element is 50 or more. In the case that the above polycrystaline compound semiconductor layer with a low resistance is used as an extrinsic base region of an heterojunction bipolar transistor, since the extrinsic base region can be formed on a dielectric film formed on a collector, it is possible to reduce the base-collector capacitance, and hence to enhance the operational speed of the heterojunction bipolar transistor.

A method and apparatus for water treatment is described, using electrolytic zone, which comprises electrolyzing water to generate an ozone-containing gas in the anode compartment of an electrolytic cell, separating the ozone-containing gas from the anolyte, and contacting the separated ozone-containing gas with the water to be treated said water to be treated being different than the water for electrolysis.
Abstract:
In a float process of flat glass production, the width of glass ribbon is controlled by regulating a tweel to manipulate the rate of supplying a molten glass through the tweel onto a molten metal bath. To minimize a fluctuation of the glass ribbon width, either of two different control modes, an integral control mode and a proportional-plus-integral control mode, is employed depending on whether or not an error between a measured width and a desired value is within a predetermined range of the error. Preferably the method of the present invention is achieved according to a sampled-data control system.
