DESIGN METHOD OF POWER DISTRIBUTION NETWORK(PDN) STRUCTURES FOR SUPPRESSING THE NOISE AND IMPROVING THE SIGNAL INTEGRITY |
摘要 |
PURPOSE: An arranging structure of an electromagnetic wave controlling structure is provided to improve a SI/PI and an EMI property by forming the electromagnetic wave controlling structure on a power plane and a ground plane in a multilayer PCB and a package structure. CONSTITUTION: An electromagnetic wave controlling structure is formed on a part of a power layer(265) or a ground layer(260). A rest of the power layer or the ground layer is used as a returning current route of a semiconductor device. A driver circuit(210) is connected to the power layer and the ground layer through a via(232). A signal wire(250) transfers the signal from the driver circuit to a load(220). A dielectric layer(270) is formed between the power layer and the grounding layer. An electromagnetic wave controlling structure blocks a transmission of a SSN generated from the dielectric layer.
