Claim 15 recites the limitation "the routing mesh layer" in line 7. There is insufficient antecedent basis for this limitation in the claim. For purposes of examination this will be interpreted as “the at least one routing mesh layer”
Claim 16 recites the limitation "the routing mesh layer" in lines 1-2. There is insufficient antecedent basis for this limitation in the claim. For purposes of examination this will be interpreted as “the at least one routing mesh layer”
Claim 17 recites the limitation "the lines" in line 2. There is insufficient antecedent basis for this limitation in the claim. For purposes of examination this will be interpreted as “the plurality of lines”
Claim 18 recites the limitation "the lines" in line 2. There is insufficient antecedent basis for this limitation in the claim. For purposes of examination this will be interpreted as “the plurality of lines”
Claim 19 recites the limitation "the routing mesh layer" in lines 1-2. There is insufficient antecedent basis for this limitation in the claim. For purposes of examination this will be interpreted as “the at least one routing mesh layer”
Claim 20 recites the limitation "the holes" in line 2. There is insufficient antecedent basis for this limitation in the claim. For purposes of examination this will be interpreted as “the plurality of holes”
Claim 21 recites the limitation "the UTM layer" in line 6. There is insufficient antecedent basis for this limitation in the claim. For purposes of examination this will be interpreted as “the at least one UTM”
Claim 21 recites the limitation "the routing mesh layers" in line 7. There is insufficient antecedent basis for this limitation in the claim. For purposes of examination this will be interpreted as “the at least one routing mesh layer”
Claim 22 recites the limitation "the routing mesh layers" in line 2. There is insufficient antecedent basis for this limitation in the claim. For purposes of examination this will be interpreted as “the at least one routing mesh layer”

Allowable Subject Matter
Claims 1-7 and 15-27 would be allowed if rewritten to overcome the 112 rejections above.
The following is a statement of reasons for the indication of allowable subject matter: the closest prior art of record, Nagarajan (US 2023/0420384), Gu (US 2021/0233934), Pluymers (US Pat. No. 6,081,989), fail to disclose (by themselves or in combination) the following limitations in combination with the rest of the claim:
Regarding Claim 1 (from which claims 2-7 and 27 depend), at least one Ultra Thick Metal (UTM) layer, stacked on the RF circuit; and at least one aluminum (AP) mesh layer, wherein the at least one aluminum mesh layer is stacked on the ate least one UTM layer…
Regarding Claim 15 (from which claims 16-20 depend), at least one Ultra Thick Metal (UTM) layer, stacked on the RF circuit; and an interposer, including at least one routing mesh layer, wherein the interposer is stacked on the semiconductor device…
Regarding Claim 21 (from which claims 22-26 depend), at least one Ultra Thick Metal (UTM) layer, stacked on the RF circuit; and two interposers, each including at least one routing mesh layer, wherein the interposers are formed on two sides of the semiconductor device…
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
Nagarajan (US 2023/0420384) discloses (Fig. 3) a mesh RFI shield 348 and RF device 304. Nagarajan does not disclose an UTM or aluminum mesh layer.
Gu (US 2021/0233934) discloses (Fig. 13) RF circuitry 118, an FEOL 104 structure connected with a BEOL 106 connected to metallization layer 108. Gu does not disclose an UTM or aluminum mesh layer.
Pluymers (US Pat. No. 6,081,989) discloses (Fig. 4h) RF manifold 430, connection traces 431 and metallization layer 32. Pluymers does not disclose an UTM or aluminum mesh layer.
