Embodiments of the present disclosure generally relate to flexible substrate fabrication. In particular, embodiments described herein relate to an apparatus and methods for flexible substrate fabrication using nip rollers to improve tension uniformity. In one embodiment, a roller assembly includes a primary roller for transporting a flexible substrate, wherein the primary roller has a first end and a second end, wherein the flexible substrate has a coating disposed hereon, and wherein one or more edge regions are not covered by the coating. The roller assembly further includes a first nip roller disposed at the first end of the primary roller that contacts a first edge region of the one or more edge regions, and a second nip roller disposed at the second end of the primary roller that contacts a second edge region of the one or more edge regions.

Inclusion of special roller to avoid creasing, wrinkling and distortion of flexible substrate in roll to roll process

A method and apparatus for thermal evaporation are provided. The thermal evaporator includes a flat crucible design, which provides an increased surface area for evaporation of the material to be deposited relative to conventional designs. The increased surface area for evaporation means that the more vapor of the evaporated material can be produced, which increases pressure inside the evaporator body leading to increased flow of the evaporated material out of the nozzles. The flat crucible can be attached to an evaporator body of the thermal evaporator. The flat crucible can be integrated within the evaporator body. The evaporator body can include a plurality of longitudinal grooves, which increase the surface area of the evaporator body. The thermal evaporator can include a plurality of baffles which divide the thermal evaporator into separate compartments.

Evaporator for effective surface area evaporation

A method and apparatus for fabricating electrodes used in energy storage devices are provided. In some implementations a surface of the electrode is activated for (a) a pre-treatment process to remove loosely held particles from the electrode surface; (b) a pre-treatment process to activate the surface of the electrode material for improved bonding or wetting for subsequently deposited materials; (c) a post-treatment of the pre-lithiation layer to improve subsequent bonding with additionally deposited layer, for example, passivation layers; and/or (d) a post-treatment of the pre-lithiation layer to improve/accelerate absorption of the lithium into the underlying electrode material.

Pretreatment and post-treatment of electrode surfaces

A wireless communication device having an integrated antenna, and methods for making and using the same are disclosed. The device generally includes (a) a substrate; (b) an integrated circuit (IC) comprising a plurality of printed and/or thin film layers and/or structures on the substrate, (c) a dielectric or insulator layer in at least one area of the substrate other than the IC; and (d) an antenna on the dielectric or insulator layer, comprising one or more metal traces. The plurality of printed and/or thin film layers and/or structures include an uppermost layer of metal. The antenna has (i) an inner terminal continuous with the uppermost layer of metal or connected to the uppermost layer of metal through one or more contacts, and (ii) an outer terminal connected to the uppermost layer of metal through one or more contacts and optionally a metal bridge or strap.
