CONSTITUTION: A lead frame body is made of copper. The lead frame body is used as a basic frame of a semiconductor package(100). A chip pad(102) is formed in the lead frame to load a semiconductor chip(108). A recess(104) is formed at the chip loading position. A groove(112) is formed at edge portions of the recess to adjust the height of an adhesive. The groove is formed by using half etching.

Abstract: PURPOSE: A method for developing bioactive implant of titanium and titanium alloy by surface treatment is provided to shorten recuperation time after operation and guide stable joint with bone by forming hydro-titania on the surface of titanium and titanium alloy, thereby improving bonding force and biocompatibility between bone and material. CONSTITUTION: The method for developing bioactive implant of titanium and titanium alloy by surface treatment is characterized in that pure titanium are titanium alloy comprising pure titanium and other metals including Al, Ta, Nb, V, Zr, Pt, Mg and Na are used as a material for the bioactive implant, wherein the surface treatment comprises first surface treatment process of treating the surface of titanium and titanium alloy using a mixed solution of hydrofluoric acid and nitric acid; second surface treatment process of treating the surface of titanium and titanium alloy using a hydrogen peroxide mixed solution comprising hydrogen peroxide or metal chlorides; and third surface treatment process of heat treating the washed and dried surface of titanium and titanium alloy after washing the surface of titanium and titanium alloy using distilled water and drying the washed surface of titanium and titanium alloy, wherein a mixed solution in which hydrofluoric acid, nitric acid and distilled water are mixed in a mixing ratio of 1:1.5:6 vol.% is used in the first surface treatment process, wherein a hydrogen peroxide aqueous solution containing hydrogen peroxide or metal chlorides including NaCl, KCl, MgCl2, SnCl2, SiCl2, CuCl2, PdCl2, NiCl2, TaCl2, NbCl2, VCl2, ZrCl2 and CaCl2 is used in the second surface treatment process, and wherein the third surface treatment process is completed by performing heat treatment at a temperature of 200 to 500 deg.C for 0.5 to 2 hours.
