In some embodiments, a reducing gas ambient containing a reducing agent is established in a batch process chamber before substrates are subjected to a deposition. The characteristic of this system is that the radio peripheral and multi-purpose transmissionreception device, as required, can be converted to a wired mouse, track ball or touch panel, and may function as a wired mouse, track ball or touch panel in case of insufficient power, power failure, channel interference or radio transmissionreception failure. The block can include one or more graphical entities and receiving a user input defining a block can include receiving one or more user inputs manipulating a graphical representation of the block. The contact points have circumferential spaces therebetween defining a diameter smaller than the diameter defined by the contact points.
