Description

Technical Field

[0001] The present invention relates to the field of semiconductor processing, and specifically to an anti-clogging gas showerhead. Background Art

[0002] In the semiconductor industry, when preparing semiconductor products, it is often necessary to form a required film or crystal structure on the semiconductor material through a vapor growth technique. When performing vapor growth processing, one or more gas mixtures participating in the reaction need to be evenly delivered into the process chamber through a gas showerhead; When the existing gas showerheads for semiconductor vapor growth are in use, a variety of reaction gases are mixed into a uniform composite gas inside them, and then evenly ejected through a number of small holes below the gas showerhead. However, when a variety of gases are mixed inside the gas showerhead, the molecules are in constant thermal motion and they collide frequently. In a semiconductor vapor growth system, the gases are usually transported and reacted under a certain pressure and flow rate, and the collision frequency between molecules is higher, thus increasing the temperature of the mixed gas. When the temperature inside the gas showerhead is high for a long time, internal material peeling may occur, resulting in clogging of the outlet small holes. In addition, when the gas participating in the reaction is a high-boiling metal organic compound, when it is transported from a high-temperature gas source to a relatively low-temperature showerhead area, it may cool and condense into a liquid or solid, which will also clog the outlet small holes.

According to the number of gases required to participate in the reaction, a reaction assembly pipe 3 with a corresponding number of reaction gas source connection grooves 6 and spiral gas pipes 8 is selected. When a variety of gases participating in the reaction enter the reaction gas source connection grooves 6 under high pressure, they enter the spiral gas pipes 8 through the reversing gas grooves 7, causing a change in the gas flow direction, so that the multiple gas flows spiral along the inner wall of the conical mixing cavity 5 in the conical mixing cavity 5, and under the converging action of the conical surface, they are preliminarily mixed.

[0020] An enhanced mixing component is provided to further enhance the mixing of the reaction gas after preliminary mixing.

After the refrigerant substance entering the second refrigerant tank 22 controls the temperatures of the conical diversion slot 11, the flow direction changing diversion slot 12, the first arc-shaped flow disturbing slot 13, and the second arc-shaped flow disturbing slot 14, it enters the third refrigerant tank 25 through the annular docking slot 24 to control the temperature inside the conical mixing cavity 5, and finally is discharged from the circulation discharge joint 28 for circulation; The gas that has undergone preliminary mixing and enhanced mixing enters the gas spray tray 1 and is blown towards the process chamber through the air outlet holes to participate in the vapor-phase growth processing of semiconductors.

[0023] Embodiment 2: On the basis of Embodiment 1, a collection and treatment component is provided to collect condensed water from the high-boiling-point metal organic compound gas that may generate condensed water vapor and discharge it at a selected time.

The collection and treatment component includes a collection cylinder 17. A collection ball groove 29 is provided at the lower end of the collection cylinder 17, and the lower end of the central connection tube 10 is inserted into the collection ball groove 29. A threaded connection ring 16 is provided at the lower end of the reaction assembly tube 3.

A plurality of diversion air holes 20 are obliquely opened inward on the outer peripheral side of the collection cylinder 17, and the tubular ceramic inorganic membrane 19 is sleeved and attached to the outer peripheral side of the collection cylinder 17. When the high-boiling-point metal organic compound gas enters the conical mixing cavity 5 and the enhanced mixing seat 9, if condensed water is generated, it can be dripped into the collection ball groove 29 of the collection cylinder 17 through the mixing and permeating groove 15 for collection. During this period, the mixed gas can be blown out through the inclined diversion air holes 20 to prevent the condensed water droplets from falling off the collection cylinder 17 and the collection ball groove 29; The setting of the tubular ceramic inorganic membrane 19 can further enhance the filtration of internal particles of the mixed gas to prevent blockage of the air outlet holes of the gas spraying disc 1. Similarly, when the gas fed into the conical mixing cavity 5 is a non-condensable gas, the tubular ceramic inorganic membrane 19 can also be used to further enhance the filtration of it.

[0024] The inner cavity of the central connection pipe 10 placed in the collection ball groove 29 is provided with a lifting relief groove 30. The inner diameter of the lifting relief groove 30 is larger than that of the central connection pipe 10. A spring partition plate 33 is horizontally arranged in the lifting relief groove 30 through a support rod. A downward pressure spring 34 is arranged at the lower end of the spring partition plate 33. An anti - detachment plate 32 is arranged at the lower end of the downward pressure spring 34. A piston rod 31 is arranged at the center of the lower end of the anti - detachment plate 32. The piston rod 31 is vertically and movably inserted into the inner cavity of the central connection pipe 10. The length of the piston rod 31 is larger than that of the downward pressure spring 34. An extension rod is arranged at the center of the lower end of the piston rod 31. The extension rod extends out of the central connection pipe 10 and is provided with a sealing ball head 36.

And a suction groove 37 is opened at the center of the sealing ball head 36 communicating with the transfer groove. When the refrigerant input groove 27 sends refrigerant substances into the central connection pipe 10, the piston rod 31 is always blocked by the downward pressure of the downward pressure spring 34 and in cooperation with the pressure of the incoming refrigerant, and always blocks the suction holes 38. When it is necessary to discharge the condensed water accumulated at the bottom of the collection ball groove 29, the circulation discharge joint 28 is blocked, and then the negative pressure suction device is connected to the refrigerant input groove 27. Under the action of high negative pressure, the piston rod 31 compresses the downward pressure spring 34 and rises. At this time, the suction holes 38 are connected to the lifting relief groove 30. The condensed water at the bottom of the collection ball groove 29 can be sucked and lifted through the suction groove 37, and discharged through the central connection pipe 10 and the refrigerant input groove 27. Since the water vapor content in the origin is less, it can be processed according to the customized cycle according to the gas source used. It can also be processed by directly disassembling the reaction assembly pipe 3 and replacing the collection cylinder 17.
