Abstract:
A converter which generates signals to control a shaping of an energy beam that strikes a substrate comprising:a translator which translates received input shape data into shape and position signals, and translates input duration information into a duration signal, wherein said shape signals control the shaping of said beam, said position signal specifies a position of said beam on said substrate, and said duration signal specifies a duration of exposure of said beam on said substrate;a retrograde scan circuit that outputs a retrograde signal;an output circuit coupled to receive said shape signals, said retrograde signal, and said position signal, wherein said output circuit adjusts said position signal according to said retrograde signal and outputs said shape and adjusted position signals; anda timer circuit coupled to receive said duration signal from said translator circuit, wherein said timer circuit controls said duration signal that said output circuit outputs said shape signal.
