Abstract: PURPOSE:To carry out the extraction and removal of foreign materials simultaneous to the concentration of DNA in high efficiency by using a DNA fragment cut with a restriction enzyme as a raw material, separating the fragment by electrophoresis using agarose gel having low melting point, thermally decomposing the gel and extracting with a specific mixed solvent at or above the melting point of the gel. CONSTITUTION:A DNA fragment cut with a restriction, enzyme is separated by electrophoresis using agarose gel having low melting point. The band containing the objective DNA fragment is cut off from the gel and transferred into a buffer solution. The gel is dissolved with heat, a mixture of phenol and chloroform is added to the molten material at or above the melting point of the gel to extract the foreign materials with the solvent mixture, the residue is left at rest and the upper layer composed of a DNA solution is recovered. A high-purity DNA fragment can be easily prepared by the above procedure. The volume ratio of phenol to chloroform in the solvent mixture is preferably about 1 to 0.8-1.3.

Title: Variable capacitance diode and manufacture thereof
Inventor: HIRANO KAZUO
IPC: H01L29/866
Filed: 1983-12-22
Abstract: PURPOSE:To reduce the high frequency series resistance by maintenance of the conventional capacitance-voltage characteristic by a method wherein the depth of an implantation diffused layer is controlled by the adjustment of the depth of its ion-implanted surface. CONSTITUTION:After an epitaxial layer 2 having a higher specific resistance than a semiconductor substrate 1 is formed thereon, an insulation film 3 having an aperture 6 is formed thereon. Next, the surface of the epitaxial layer in the aperture 6 is etched by t2, and the implantation diffused layer 14 is formed therein. Then, a diffused layer 15 that includes the main surface of the diffused layer 14 and has a wider area than this main surface and a much higher concentration than the impurity concentration of the diffused layer 14 is formed. The depth t2 of etching controls the spreading of an depletion layer. In other words, an increase in depth t2 and a decrease in the level of the ion-implanted surface enable the depth of the spreading surface of the depletion layer immediately under the diffused layer 14 to be made larger than the depth of the spreading surface of the depletion layer in the epitaxial layer.
