  • Patent number: 8993453
    Abstract: A method for fabricating a nonvolatile charge trap memory device and the device are described. In one embodiment, the method includes providing a substrate in an oxidation chamber, wherein the substrate comprises a first exposed crystal plane and a second exposed crystal plane, and wherein the crystal orientation of the first exposed crystal plane is different from the crystal orientation of the second exposed crystal plane. The substrate is then subjected to a radical oxidation process to form a first portion of a dielectric layer on the first exposed crystal plane and a second portion of the dielectric layer on the second exposed crystal plane, wherein the thickness of the first portion of the dielectric layer is approximately equal to the thickness of the second portion of the dielectric layer.

  • Patent number: 8940645
    Abstract: A method for fabricating a nonvolatile charge trap memory device is described. The method includes subjecting a substrate to a first oxidation process to form a tunnel oxide layer overlying a polysilicon channel, and forming over the tunnel oxide layer a multi-layer charge storing layer comprising an oxygen-rich, first layer comprising a nitride, and an oxygen-lean, second layer comprising a nitride on the first layer. The substrate is then subjected to a second oxidation process to consume a portion of the second layer and form a high-temperature-oxide (HTO) layer overlying the multi-layer charge storing layer. The stoichiometric composition of the first layer results in it being substantially trap free, and the stoichiometric composition of the second layer results in it being trap dense. The second oxidation process can comprise a plasma oxidation process or a radical oxidation process using In-Situ Steam Generation.

  • Patent number: 8592891
    Abstract: A semiconductor device and method of fabricating the same are provided. In one embodiment, the semiconductor device includes a memory transistor with an oxide-nitride-nitride-oxide (ONNO) stack disposed above a channel region. The ONNO stack comprises a tunnel dielectric layer disposed above the channel region, a multi-layer charge-trapping region disposed above the tunnel dielectric layer, and a blocking dielectric layer disposed above the multi-layer charge-trapping region. The multi-layer charge-trapping region includes a substantially trap-free layer comprising an oxygen-rich nitride and a trap-dense layer disposed above the trap-free layer. The semiconductor device further includes a strain inducing structure including a strain inducing layer disposed proximal to the ONNO stack to increase charge retention of the multi-layer charge-trapping region. Other embodiments are also disclosed.

  • Patent number: 7799670
    Abstract: A blocking layer of a non-volatile charge trap memory device is formed by oxidizing a portion of a charge trapping layer of the memory device. In one embodiment, the blocking layer is grown by a radical oxidation process at temperature below 500° C. In accordance with one implementation, the radical oxidation process involves flowing hydrogen (H2) and oxygen (O2) gas mixture into a process chamber and exposing the substrate to a plasma. In a preferred embodiment, a high density plasma (HDP) chamber is employed to oxidize a portion of the charge trapping layer. In further embodiments, a portion of a silicon-rich silicon oxynitride charge trapping layer is consumptively oxidized to form the blocking layer and provide an increased memory window relative to oxidation of a nitrogen-rich silicon oxynitride layer.
