adio 

Frequency (CESAR), a new generation of versatile RF power supplies for 
semiconductor production, and general plasma processing. This 13.56 MHz 
generator employs parallel excited circuitry in a compact, 19" rack-mountable 
designs. Typical applications include sputtering, reactive ion etching, RF bias, 
plasma polymerization, plasma surface treatment, and CO

2

 laser systems.

The CESAR generator incorporates advanced switch mode technology. This 
highly efficient, resonant switching concept results in reduced energy costs, 
reduced downtimes, and a longer lifetime for the unit.

Designed to regulate power into a broad range of output impedances, the 
CESAR generator can operate in forward, load, or external power regulation 
mode (see 

“Setting Regulation Mode” on page 5-15

).

Both manual and automatic tuning control support operation into a fixed 
impedance matching network, which simplifies system complexity, increases 
reliability, and improves process-to-process repeatability (see 

“Controlling the 

Matchbox” on page 5-20

).

You can control the CESAR generator remotely through an analog

 User Port 

(see 

“CESAR Generator User Port Options” on page 4-10

) or a serial 

Host

 

port (see 

“CESAR Generator Host Port Options” on page 4-42

). The front 

panel features a 

liquid crystal display (LCD) 

with an easy-to-use menu that 

includes widely programmable pulse functions, a target lifetime counter, and 
submenus to customize your own recipes, reflected power settings, and 
Variomatch settings (when the generator is connected to a Variomatch unit). 
In addition, you may control RF power and match settings using the front 
panel controls. For operation instructions, see 

“First-Time Operation” on 

page 5-10

 and 

“Normal Operation” on page 5-15

.

The CESAR generator operates from a 230 VAC, 50/60 Hz power source. The 
CESAR generator is air-cooled and has all power and interface-port 
connections at the rear of the generator (see 

“Rear View Drawings” on 

page 4-2

).
