Abstract:
A method for fabricating a silicon on insulator (SOI) device, comprising the steps of:preparing a silicon substrate;forming a conduction layer in the substrate;forming a buried oxide layer having a first and a second contact holes over the silicon substrate including a conduction layer;forming a first and a second contact layers within the first and the second contact holes of the buried oxide layer, respectively to contact with the conduction layer;forming a silicon layer over the buried oxide layer including the first and the second contact layers;forming an isolation layer in the silicon layer to define a device formation region;forming a gate on the device formation region of the silicon layer over the first contact layer;forming a source region and a drain region at the both side of the gate in the device formation region; andforming an impurity region for well pick-up in the silicon layer to be contacted with the second contact layer.
