A thermal chemical vapor deposition (CVD) system includes a bottom chamber, an upper chamber, a workpiece support, a heater and at least one shielding plate. The upper chamber is present over the bottom chamber. The upper chamber and the bottom chamber define a chamber space therebetween. The workpiece support is configured to support a workpiece in the chamber space. The heater is configured to apply heat to the workpiece. The shielding plate is configured to at least partially shield the bottom chamber from the heat.

Thermal chemical vapor deposition system and operating method thereof

A deposition device structure is provided. The deposition device structure includes a heater in a chamber. The deposition device structure also includes a shower head over the heater. The shower head includes holes extending from a top surface of the shower head to a bottom surface of the shower head. The bottom surface of the shower head faces the heater. The bottom surface of the shower head has a first section and a second section. The second section of the bottom surface is rougher than the first section of the bottom surface.
