Certain embodiments generally provide an improved tibial base member comprising keel portions that allow one or both cruciate ligaments to be preserved. The present invention provides a method for producing a CMOS transistor having enhanced performance since a short channel characteristic and operation power can be controlled by the duplicate punch stop layer of the pMOS region and the operation power of the nMOS is also controlled by dopant concentration of the duplicated LDD region combined by the first LDD region and the second LDD region. The processed data flow may include the data flow with the service applied to the data flow.
