摘要： Embodiments of the present invention generally provide an inductively coupled plasma (ICP) reactor having a substrate RF bias that is capable of control of the RF phase difference between the ICP source (a first RF source) and the substrate bias (a second RF source) for plasma processing reactors used in the semiconductor industry. Control of the RF phase difference provides a powerful knob for fine process tuning. For example, control of the RF phase difference may be used to control one or more of average etch rate, etch rate uniformity, etch rate skew, critical dimension (CD) uniformity, and CD skew, CD range, self DC bias control, and chamber matching.

摘要： Optical films for enhancing light extraction from self-emissive pixelated OLEDs, without introducing significant pixel blur, are disclosed. The extraction films include a flexible carrier film, and a first and second layer carried by the carrier film. The first layer has a nanovoided morphology, includes a polymer binder, and may have a refractive index less than 1.35 or 1.3. An embedded structured surface of light extraction elements is formed between the first and second layers. The extraction film includes a major coupling surface for attachment to an outer surface of the light source. The film is configured such that a land portion between the structured surface and the major coupling surface is thinner than a specified amount, e.g., less than 50, 25, or 10 microns, or less than a thickness of the carrier film.

摘要： Optical films for enhancing light extraction from self-emissive light sources such as bottom-emitting or top-emitting OLEDs are disclosed. The extraction films typically include a flexible carrier film, and a first and second layer carried by the carrier film. The first or second layer has a nanovoided morphology and includes a polymer binder, and may also have a refractive index less than 1.35 or 1.3. An embedded structured surface of light extraction elements is formed between the first and second layers. The light extraction elements may be primarily diffractive elements adapted to be disposed within an evanescent zone of the OLED, or they may be primarily refractive elements adapted to be disposed outside the evanescent zone. The extraction film may also include a third layer, and a second embedded structured surface may be formed between the third layer and the first layer.

摘要： Extended area lighting devices, which are useful e.g. as luminaires, include a light guide and diffractive surface features on a major surface of the light guide. The diffractive surface features are tailored to extract guided-mode light from the light guide. The light guides can be combined with other components and features such as light source(s) to inject guided-mode light into the light guide, light source(s) to project light through the light guide as non-guided-mode light, a framework of interconnected support members (attached to multiple such light guides), and/or a patterned low index subsurface layer that selectively blocks some guided mode light from reaching the diffractive surface features, to provide unique and useful lighting devices. Related optical devices, and optical films having diffractive features that can be used to construct such devices and light guides, are also disclosed.
