    Abstract: A portable electronic device has a device housing, and an electronic camera module in the device housing. The module has a focusing lens to focus light from a scene, an imaging sensor to receive the focused light, and an electro-optic variable aperture to allow different amounts of the light from the scene to reach the imaging sensor. The electro-optic variable aperture may include a first aperture stack placed on a transparent substrate and a second aperture stack placed on the first aperture stack. The first aperture stack defines a first aperture and the second aperture stack defines a second aperture that is larger than the first aperture. Each aperture stack includes a transparent conductive oxide layer that is common with the adjacent aperture stack. Alternatively the electro-optic variable aperture may include an aperture stack that has two transparent conductive oxide layer layers, where one layer is in the form of concentric annuli.

    Abstract: Sputter deposition systems and methods for depositing film coatings on one or more substrates are disclosed. The systems and methods are used to prevent or reduce an amount of defects within a deposited film. The methods involve removing defect-related particles that are formed during a deposition process from certain regions of the sputter deposition system and preventing the defect-related particles from detrimentally affecting the quality of the deposited film. In particular embodiments, methods involve creating a flow of gas from a deposition region to a particle collection region the sputter deposition system such that the defect-related particles are entrained within the flow of gas and away from the deposition region. In particular embodiments, the sputter deposition system is a meta-mode sputter deposition system.

    Abstract: An electronic device may have transparent members such as display cover layers and camera windows. A transparent member such as a sapphire member may be provided with an antireflection coating. The antireflection coating may have a stack of dielectric thin-film interference filter layers that form a thin-film interference filter that suppresses visible light reflections. The stack of dielectric thin-film interference filter layers may have thicknesses and materials that provide the thin-film interference filter and coating with low light reflection properties while enhancing scratch resistance. An adhesion layer may be used to help adhere the stack of thin-film interference filter layer to the transparent member. An antismudge coating such as a fluoropolymer coating may be used to reduce smudging. Graded layers and layers with elevated hardness values may be used in the coating.

    Abstract: An electronic device may have a display that is protected by a transparent cover layer. The transparent cover layer may include a laser-annealed sapphire coating on the outer surface of a glass substrate or other transparent substrate. The sapphire coating may provide the display with a hard, scratch-resistant outer surface. The sapphire coating may be formed by coating a glass substrate with a thin film of amorphous aluminum oxide. The aluminum oxide thin film may be locally heated to transform the amorphous aluminum oxide into alpha-phase aluminum oxide (sapphire). Local heating may be achieved by laser annealing the aluminum oxide coating with a carbon dioxide laser. The laser may produce laser light having a wavelength that is absorbed in the aluminum oxide coating without being absorbed by the glass substrate so that the glass substrate is not damaged during the laser annealing process.
