Abstract:
A free-standing multi-laminate hermetic sheet includes a first carrier film, a hermetic inorganic thin film formed over the first carrier film, and a second carrier film formed over the hermetic inorganic thin film. A workpiece can be hermetically sealed using the multi-laminate sheet, which can be applied to the workpiece in a step separate from a formation step of either the multi-laminate sheet or the workpiece.
Abstract:
A thin film battery comprises a substrate, anode and cathode current collector layers formed over the substrate, anode and cathode layers formed over and in electrical contact with respective ones of the current collector layers, and an electrolyte layer formed between the anode and cathode layers. The thin film battery further comprises a barrier layer formed from a material such as tin oxide, tin phosphate, tin fluorophosphate, chalcogenide glass, tellurite glass or borate glass. The barrier layer is configured to encapsulate the thin film battery layers and substantially inhibit or prevent exposure of the thin film battery layers to air or moisture.
Abstract:
A method is disclosed for inhibiting oxygen and moisture penetration of a device comprising the steps of depositing a tin phosphate low liquidus temperature (LLT) inorganic material on at least a portion of the device to create a deposited tin phosphate LLT material, and heat treating the deposited LLT material in a substantially oxygen and moisture free environment to form a hermetic seal; wherein the step of depositing the LLT material comprises the use of a resistive heating element comprising tungsten. An organic electronic device is also disclosed comprising a substrate plate, at least one electronic or optoelectronic layer, and a tin phosphate LLT barrier layer, wherein the electronic or optoelectronic layer is hermetically sealed between the tin phosphate LLT barrier layer and the substrate plate. An apparatus is also disclosed having at least a portion thereof sealed with a tin phosphate LLT barrier layer.
Abstract:
Tungsten-doped tin-fluorophosphate glasses are described herein which exhibit excellent humidity resistance, thermal resistance, and have a low glass transition temperature which makes them suitable for low temperature sealing applications, such as for encapsulating electronic components. In one embodiment, these glasses comprise 55-75% Sn, 4-14% P, 6-24% O, 4-22% F, and 0.15-15% W on a weight percent elemental basis.
Abstract:
A method for hermetically sealing a device without performing a heat treatment step and the resulting hermetically sealed device are described herein. The method includes the steps of: (1) positioning the un-encapsulated device in a desired location with respect to a deposition device; and (2) using the deposition device to deposit a sealing material over at least a portion of the un-encapsulated device to form a hermetically sealed device without having to perform a post-deposition heat treating step. For instance, the sealing material can be a Sn2+-containing inorganic oxide material or a low liquidus temperature inorganic material.
Abstract:
A flexible substrate is described herein which is made from a freestanding inorganic material (e.g., mica paper, carbon paper, glass fiber paper) with pores/interstices that have been impregnated with a special impregnating material (e.g., silsesquioxane, alkali silicate glass with weight ratio of SiO2/X2O (X is alkali Na, K etc.) between 1.6-3.5). In one embodiment, the flexible substrate is made by: (1) providing a freestanding inorganic material; (2) providing an impregnating material; (3) impregnating the pores/interstices within the freestanding inorganic material with the impregnating material; and (4) curing the freestanding inorganic material with the impregnated pores/interstices to form the flexible substrate. The flexible substrate is typically used to make a flexible display or a flexible electronic.
