The present invention provides an apparatus for sharing a user control enhanced digital identity that allows a user to have all controls and control the flow of identity sharing on the user basis when the user shares user’s personal information. The adjustable clamp assembly comprises a handlebar clamp to secure the handlebar to the adjustable clamp assembly. The second process comprises supplying a second processing liquid containing ammonia hydrogen peroxide mixture to the rear surface of the substrate after the first process is completed, thereby processing the rear surface of the substrate with the second processing liquid. A type of print receiving medium is supplied to the media indexing system. Each memory device is serially connected to the adjacent memory device through the vias and solder balls on each package. A memory cell string includes a plurality of transistors that are disposed on the substrate in the vertical direction along a vertical sidewall of the channel layer.
