STACKED COMPLEX CHIP DEVICE, CAPABLE OF REDUCING THE NUMBER OF ESD PROTECTION DEVICES

摘要

PURPOSE: A stacked complex chip device is provided to block ESD(Electrostatic Discharge) inputted to a power line and a data line by integrating a suppressor and a varistor with one chip.;CONSTITUTION: A stacked complex chip device(80) includes a suppressor(1) and a varistor layer(2). A discharge unit is formed on one side among left and right sides of a suppressor. The varistor layer includes a first internal electrode and a second internal electrode. The first and second internal electrodes are partially overlapped. The suppressor and the varistor are integrated with one chip. The varistor layer is comprised of one layer or more. The first and second internal electrodes are formed on the different layers.;COPYRIGHT KIPO 2010
