Abstract: PURPOSE: A semiconductor device having a fusible link is provided not to cause any damage to a bit line during a cutting of the fusible link. CONSTITUTION: In a semiconductor device, a fusible link is used to replace a defective circuit with a redundant circuit. To fabricate the fusible link, a barrier metal(5) and a metal layer(3) are formed and patterned on a wafer(1). The metal layer(3) is used as a bit line, whereas the barrier metal(5) preventing a diffusion between the wafer(1) and the metal layer(3) is used as the fusible link. Next, an oxide layer and a first passivation layer(7) are successively deposited on the metal layer(3). The first passivation layer(7) is then partly removed, and subsequently exposed portions of the metal layer(3) are also removed. Therefore, some portions of the barrier metal(5) become exposed. Next, a second passivation layer(7) is wholly deposited. Since the passivation layer(7) is formed in twice, the barrier metal(5) acting as the fusible link is coated with a thinner passivation layer than that on the metal layer(3) acting as the bit line. The fusible link having the thinner passivation layer is therefore easy to cut, and thereby the neighboring bit line is barely damaged.

Abstract: PURPOSE: A method for forming a silicon oxide layer of a semiconductor element is provided to improve the reliance of the silicon oxide layer and to reduce the manufacturing cost of the semiconductor element by pre-treating a silicon substrate or a lower layer of the silicon oxide layer. CONSTITUTION: After a wafer is loaded in a chamber, a lower layer of the wafer to which a thin silicon oxide layer is formed is pre-treated by a plasma process. Then, the wafer is further treated by oxygen plasma. The pressure of the chamber is set in the range of 10-80mT. The temperature of the wafer loading apparatus, which is loaded into the chamber, is set above 100°C. If the lower layer is a silicon substrate, the pre-treating process is performed by using a nitrogen gas without applying a bias power.
