in the above case, "advanced" is not used to describe "manufacturing" but "techniques"

In the context of the European and Australian patent law, the term "state of the art" is a concept used in the process of assessing and asserting novelty.
This term is usually applied in Industrial & Engineering Marketing, Patent, or Patent Application.
该产品采用先进工艺制成 may be:
This product is made in the advanced state of the art.
该产品采用世界先进工艺制成 may be:
This product is made in the advanced state of the art in the world.
Of course, in some other occasions, it may have different wordings such as other previous answers.
FYI.

Another example in fact
此設計並非西門子之特殊設計。如在文件中所說明，其在空運貨物處理界是一項已為所有廠商採用之工藝設計。
This design is not a Siemens special design. It is a state of the art design in the cargo handling world used by all vendors like stated in document.

Consulted many technical dictionary and I know both culture very well.

先进工艺 --> advanced technology
