A precursor source vessel for providing vaporized precursor to a reaction chamber is provided. The precursor source vessel includes a lid having a first port, a second port, and a third port. The precursor source vessel also includes a base removably attached to the lid. The base includes a recessed region formed therein. One of the first, second, and third ports is a burp port configured to relieve the head pressure within the source vessel after the source vessel is installed but prior to use of the source vessel in semiconductor processing.

1. A precursor source vessel comprising: a lid having an upper surface comprising inlet port, an outlet port, and a burp port;a surface-mounted inlet valve in fluid communication with the inlet port;a surface-mounted outlet valve in fluid communication with the outlet port;a surface-mounted burp valve in fluid communication with the burp port;a base removably attached to said lid, said base having a recessed region formed therein, said recessed region comprising an inlet recessed pad, an outlet recessed pad, a burp recessed pad, and a channel integrally formed within said base; anda filtration apparatus connected to a bottom surface of said lid. 2. The precursor source vessel of claim 1, wherein said channel fluidly connects the inlet recessed pad, the outlet recessed pad, and the burp recessed pad. 3. The precursor source vessel of claim 2, wherein said channel includes a plurality of linear sections. 4. The precursor source vessel of claim 3, wherein at least two of said linear sections are adjacent and substantially parallel. 5. The precursor source vessel of claim 2, wherein said channel includes a plurality of arced sections. 6. The precursor source vessel of claim 5, wherein at least two of said arced sections are adjacent and substantially concentric. 7. The precursor source vessel of claim 1 further comprising a seal disposed between the lid and the base. 8. The precursor source vessel of claim 1, wherein a depth of the channel is greater than a depth of any of the inlet recessed pad, the outlet recessed pad, and the burp recessed pad. 9. The precursor source vessel of claim 1, wherein each of said inlet valve, said outlet valve, and said burp valve is mounted flush with an upper surface of said lid. 10. The precursor source vessel of claim 1, wherein said channel is machined into said base. 11. The precursor source vessel of claim 1, wherein said channel is a tortuous pathway. 12. A precursor source vessel comprising: a base having a recessed region integrally formed therein, said recessed region comprising an inlet recessed pad, an outlet recessed pad, a burp recessed pad, and a channel, said inlet recessed pad, said outlet recessed pad, and said burp recessed pad extending downwardly from a contact surface of said base;a lid removably attached to said base, said lid having an upper surface comprising an inlet port, an outlet port, and a burp port; anda burp valve operatively attached to said lid, and wherein said burp valve is operatively connected to said burp port. 13. The precursor source vessel of claim 12 further comprising a burp filter mounted flush with an upper surface of said lid adjacent to said burp port. 14. The precursor source vessel of claim 12, wherein said burp port is directly fluidly connected to a burp gas line that bypasses a reaction chamber. 15. A precursor source vessel comprising: a base having a bottom surface, a contact surface, a side surface extending between said contact and bottom surfaces, and an inner surface extending from said contact surface to define a recessed region within said base, said recessed region comprising an inlet recessed pad, an outlet recessed pad, a burp recessed pad, and a channel integrally formed within said base;a lid removably attached to said base, said lid having an upper surface comprising an inlet port, an outlet port, and a burp port. 16. The precursor source vessel of claim 15, wherein said lid includes an upper surface, a lower surface and a side surface extending between said upper and lower surfaces, and wherein said lower surface of said lid is in an abutting relationship with said contact surface of said base when said lid is attached to said base. 17. The precursor source vessel of claim 16 further comprising an interior volume defined between said inner surface of said base and said lower surface of said lid. 18. The precursor source vessel of claim 15, wherein said recessed region provides a fluid pathway between said inlet port and said outlet port. 19. The precursor source vessel of claim 18 wherein said inlet recessed pad, said outlet recessed pad, and said channel are machined into said base. 20. The precursor source vessel of claim 19, wherein said channel includes a plurality of linear sections. 21. The precursor source vessel of claim 20, wherein at least two of said linear sections are adjacent and substantially parallel. 22. The precursor source vessel of claim 19, wherein said channel includes a plurality of arced sections. 23. The precursor source vessel of claim 22, wherein at least two of said arced sections are adjacent and substantially concentric. 24. The precursor source vessel of claim 15 further comprising a heating assembly disposed within said base. 25. A precursor source vessel comprising: a lid having an upper surface comprising a first port, a second port, and a third port; and a base removably attached to said lid, said base having a recessed region formed therein, said base comprising an inlet recessed pad, an outlet recessed pad, a burp recessed pad, and a channel integrally formed within said base.
