Inventor: HOJO JUNICHI
IPC: H04N5/341
Filed: 1991-02-14
Abstract: PURPOSE:To enable an efficiency of a horizontal transfer to be improved without poorly affecting other element portions by implanting a donor at a P well with a high energy which does not affect other element parts adversely. CONSTITUTION:A P-type well 12 of a second conductivity type is formed on the surface side of for example an N-type semiconductor substrate 11 which is of first conductivity type and an N-type region 13 is formed on the surface side of this P well 12. By implanting boron into the P well 12, potential becomes shallow over an entire region. After this, a high-energy donor which does not affect other element parts such as a transfer region 14 adversely is implanted into the P well, thus enabling a region of the P well 12 to be completely depleted while maintaining a potential of the N-type region 13. In this case, there is a risk for enabling the potential of the surface transfer region 14 to be deeper so that the dosage of donor needs to be optimized.

Filed: 1990-02-23
Abstract: PURPOSE:To increase the adsorption capacity and adsorption velocity of V and to easily remove V by adsorption by bringing a chelate resin having a specific functional group into contact with a V-containing aqueous solution. CONSTITUTION:A chelate resin having at least one functional group selected from the functional groups which contain carboxylic acid radicals, phosphoric acid radicals, and inorganic acids thereof and are joined to high polymer principal chains via two or more secondary or tertiary amino groups is used as an adsorbent. This chelate resin is brought into contact with a V-containing solution, e.g. by passing the solution through a column. It is preferable to perform the above treatment while regulating the pH of the V-containing solution to <=10. Further, the amount of the chelate resin used is regulated to about 10-100000 per part by weight of V in the V-containing solution, and also contact time is regulated to about 1min-24hr. Since this chelate resin can adsorb V highly selectively from the solution containing V and coexisting ions, V can be easily separated and recovered.
