It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the device of Luo with the different vertical levels taught by Tung in order to improve electrical isolation between adjacent memory cells (see Tung [0018]: “The dielectric insert structures 30a are deeper than the isolation structure 20a and may improve electrical isolation between adjacent memory cells , so that signal crosstalk between the memory cells may be reduced.”) With regards to Claim 14 , Luo discloses the semiconductor device of claim 8.

It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to substitute the material of the cutting insulating layers of Luo with the differing materials taught by Tung in order to create a depletion region and further obstruct leakage currents between memory cells (see Tung [0015] , [0016], and [0018]: “In an embodiment, the first dielectric layer 20 is made of silicon oxide, and the second dielectric layer 30 is made of silicon nitride. The second dielectric layer 30 may be used as a solid-state doping (SSD) source layer, and may include neutral dopants (such as carbon) or dopants of a specific conductivity type. In some embodiments, the second dielectric layer 30 may include dopants of a second conductivity type opposite to the first conductivity type of the well region.”; “ In some embodiments when the dielectric insert structures 30a includes dopants and is used as a solid state doping (SSD) source layer, an anneal process may be performed to drive the dopants from the dielectric insert structures 30a into the substrate 10 after forming the word line trenches 40 to form the doped regions 30b in the substrate 10 and directly under the isolation trench 14. ”; “Furthermore, by forming a doped regions 30b with a conductivity type opposite to the conductivity type of the substrate 10 (or the well region), a depletion region may be formed to obstruct leakage currents between memory cells .” ; in order to create the depletion region 30b , the secondary cutting insulating layer (Tung Fig. 9, second dielectric layer 30 (30a) ) must be doped , which means the primary and secondary cutting insulators are made of different materials. ). With regards to Claim 15 , Luo disclose s the semiconductor device of claim 8, further comprising a first word line structure (Luo Fig. 2N, first word line 270A) in the active area (Luo Fig. 2N, active areas 201) .

With regards to Claim 17 , Luo discloses the semiconductor device of claim 16 . Luo does not disclose a bottom surface of the first word line dielectric layer is at a vertical level higher than a bottom surface of the secondary cutting insulating layer. Tung discloses a bottom surface of the first word line dielectric layer (Tung Fig. 9 , gate dielectric layer 42) is at a vertical level higher than a bottom surface of the secondary cutting insulating layer (Tung Fig. 9 and above Image D) . It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the word line of Luo with the different vertical levels described by Tung in order to further obstruct leakage currents between memory cells (see Tung [0016] and [0018] : “ In some embodiments when the dielectric insert structures 30a includes dopants and is used as a solid state doping (SSD) source layer, an anneal process may be performed to drive the dopants from the dielectric insert structures 30a into the substrate 10 after forming the word line trenches 40 to form the doped regions 30b in the substrate 10 and directly under the isolation trench 14. ”; “Furthermore, by forming a doped regions 30b with a conductivity type opposite to the conductivity type of the substrate 10 (or the well region), a depletion region may be formed to obstruct leakage currents between memory cells.” ; the doped secondary cutting insulating layer (Tung Fig. 9, second dielectric layer 30 (30a) ) extends further into the substrate 1 0 than the bottom of the word line WL and creates the depletion region 30b , which is necessary to further obstruct leakage currents.). With regards to Claim 18 , Tung (in combination with Luo) discloses the semiconductor device of claim 17, wherein the first word line dielectric layer (Tung Fig. 9 , gate dielectric layer 42) and the secondary cutting insulating layer (Tung Fig. 9, second dielectric layer 30 (30a) ) comprise the same material ("the material of the gate dielectric layer 42 may include silicon oxide, silicon nitride, high-k dielectric materials, or a combination thereof, but is not limited thereto,” (see Tung [0017]) and that "the second dielectric layer 30 is made of a dielectric material such as silicon oxide, silicon nitride, silicon oxynitride, or a combination thereof,” (see Tung [0015]), showing that the gate dielectric layer 42 and the second dielectric layer 30 can comprise of the same material) .
