A mask layer is applied to a surface of a semiconductor structure or a seed layer deposited on the surface. In an example, the holder includes a bolt assembly having a first end to attach to a vehicle and a second end to quick release a support plate for holding the vehicle license plate. The axis, direction and speed of the three-directional object rotation are repeatedly calculated in a fixed cycle only while the coordinate is kept defined by the user by continuously touching the display screen. Each wick segment has at least one spring that urges the segment into contacting engagement with the transfer roll, while the cam for that segment is disposed to engage the follower and flex the wick segment off the transfer roll against the action of the spring when the lobe of the cam is in contacting engagement with the follower. Compounds prepared by the processes of the invention have demonstrated activity as histamine-3 receptor ligands. The resilient insert and the base cooperate to support a top surface of the resilient insert at an angle with respect to a lower surface of the base.
