Title:
SEMICONDUCTOR DEVICE AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2010/079816
Kind Code:
A1
Abstract:
Provided is a semiconductor device loaded with a variable resistance element that can increase reliability, increase density and prevent deterioration of insulating characteristics and yield. The semiconductor device has a variable resistance element inside a multilayer wiring layer on a semiconductor substrate. Said variable resistance element has a configuration wherein a variable resistance element film that changes resistance is interposed between an upper electrode and a lower electrode. Said multilayer wiring layer is provided at least with wiring that is electrically connected to said lower electrode and a plug that is electrically connected to said upper electrode. Said wiring also serves as said lower electrode (figure 1).
