Abstract: PURPOSE: A process of preparing a ceramic composite for easy control of biosolubility by improving sinterability of a hydroxyapatite and tricalcium phosphate complex is provided which increases strength of the ceramic composite by 3 times while obtaining high density ceramic. Thus obtained ceramic composite can be applied to an artificial tooth and bone-graft material. CONSTITUTION: About 0.2 to 10% by weight of a magnesium salt is added to a complex of hydroxyapatite and tricalcium phosphate in a ratio of 5:95 to 80:20. The magnesium salt comprises one or more selected from the group consisting of magnesium nitrate, magnesium chloride, magnesium oxide, magnesium hydroxide and magnesium carbonate. In a case of synthesizing the hydroxyapatite and tricalcium phosphate, a magnesium is added instead of a calcium salt and then sintered.

Abstract: A single electron transistor having a self-aligned trench and a fabricating method thereof are provided to form a tunneling barrier irrelevant to a voltage applied to a gate by forming self-aligned trenches at both sides of the gate. Source and drain regions(22a,24a) are formed on a single crystal silicon layer of an SOI substrate to be separated from each other. A channel region defined by a predetermined small pattern is between the source and drain regions. A gate dielectric(30) is formed on an upper portion of the channel region. A gate(40) is formed on an upper portion of the gate dielectric. A trench(70) is self-aligned at both sides of the gate to be formed in a thickness direction of the channel region. LOCOS dielectric layers(60) are respectively formed on upper portions of the source and drain regions. A dielectric sidewall spacer is formed an upper portion of an end of each LOCOS dielectric layer in parallel with the trench.
