  • Publication number: 20110256671
    Abstract: A semiconductor memory module having a reverse mounted chip resistor, and a method of fabricating the same are provided. By reverse mounting the chip resistor on the semiconductor memory module, the resistive material is protected, thereby preventing open circuits caused by damage to the resistive material. Also, a chip-resistor connection pad of a module substrate is formed to extend higher from the module substrate than other connection pads connected to other elements. Thus, the resistive material of the chip resistor does not contact the module substrate, thereby preventing poor alignment and defective connections.
