The present invention provides a semiconductor device and a method of manufacturing the same. According to an embodiment of the present invention, a silicon oxide layer is formed over lower electrode contact plugs by using a selective oxidation process, wherein the silicon oxide layer has a thickness greater than an oxidized portion of an adjacent isolation layer (i.e., an isolation insulating layer). Accordingly, a concave contact area between a lower electrode and the lower electrode contact plug can be desirably be secured following etching of the silicon oxide layer in a subsequent process. Specifically, a width of the adjacent isolation layer does not need to be increased because sequential dry and wet etch processes expose the lower electrode contact plugs in a process of forming the lower electrodes.

An improvement of joint reliability between Sn-yAg (0≦y≦4.0) solder and Ni—P under-bump metallic layers is achieved by cobalt (Co) addition. A solder joint with improved joint reliability is formed between a solder part of an electronic packaging and an under-bump metallic (UBM) layer, which has a specific structure comprising Sn-yAg-xCo (0.02≦x≦0.1, 0≦y≦4.0) alloy solder containing cobalt (Co) ingredient bonded to a Ni—P UBM. Also, a solder joint with a joint structure comprising Sn-yAg-xCo (0.02≦x≦0.1, 0≦y≦4.0) alloy solder with addition of Co ingredient and Ni—P UBM is formed, which is inserted between a PCB substrate and a silicon chip to join the same.
