  • Patent number: 10266937
    Abstract: A coated article includes a low emissivity (low-E) coating having at least one infrared (IR) reflecting layer of a material such as silver, gold, or the like, and at least one hafnium (Hf) inclusive high index nitrided dielectric layer. In certain example embodiments, the hafnium inclusive high index nitrided dielectric layer(s) may be of or include one or more of HfSiAlN, HfZrSiAlN, HfSiN, HfAlN, and/or HfAlZrN. The high index layer may be a transparent dielectric high index layer, with a high refractive index (n) and/or low k value. In example embodiments, the low-E coating may be used in applications such as monolithic or insulating glass (IG) window units, vehicle windows, or the like.

  • Patent number: 10213988
    Abstract: A coated article includes a low emissivity (low-E) coating having at least one infrared (IR) reflecting layer of a material such as silver, gold, or the like, and at least one high refractive index layer of or including titanium oxide and at least one additional metal. A doped titanium oxide layer(s) is designed and deposited in a manner so as to be amorphous or substantially amorphous (as opposed to crystalline) in the low-E coating, so as to better withstand optional heat treatment (HT) such as thermal tempering and reduce haze. The high index layer may be a transparent dielectric high index layer in preferred embodiments, which may be provided for antireflection purposes and/or color adjustment purposes, in addition to having thermal stability.

  • Publication number: 20180348409
    Abstract: An optical coating, such as anti-reflective coating (ARC) or colored coating for optical devices, suitable especially for mobile devices. The ARC is made up of alternating layers of low refractive index and high refractive index. At least one of the layers, preferably the top layer, is made up of nano-laminate. The nano-laminate is a structure of alternating nano-layers, each nano-layer made out of a material having refractive index similar to the layer it replaces. Optionally, each of the layers are made up of nano-laminates, such that a layer having low refractive index is made up of nano-laminates of nano-layers having low refractive index, while high index layers are made up of nano-lamonate of nano-layers having high refractive index. Each of the nano-layers is of 2-10 nanometer thickness.

  • Patent number: 9305748
    Abstract: Etch rate distributions are captured at a succession of hardware tilt angles of the RF source power applicator relative to the workpiece and their non-uniformities computed, and the behavior is modeled as a non-uniformity function for each one of at least two plasma reactors. An offset ?? in tilt angle ? between the non-uniformity functions of the two plasma reactors is detected. The two plasma reactors are then matched by performing a hardware tilt in one of them through a tilt angle equal to the offset ??.
