A vacuum process system for surface-treating work pieces uses an arc evaporation source. A plurality of feature indicators can be positioned in the grid. Each of the second plurality of multiport optical devices have a plurality of input ports for selectively receiving one of more wavelength components of the optical signal and at least one output port for selectively receiving one of more wavelength components of the optical signal. A second barrier layer is formed on a back surface of the semiconductor substrate and in a via hole formed from the back surface of the semiconductor substrate to the first barrier layer. Hinge brackets on the cabinet support either a thick door with internal storage space, a proud door or an inset door. The pointing device irradiate light onto the ball through the light source, acquires an image on a surface of the ball through the optical image sensor, and outputs data on movement direction and distance by comparing and analyzing previous and current images.
