Transistors, electronic devices including a transistor and methods of manufacturing the same are provided, the transistor includes an oxide semiconductor layer having compositions that vary in one direction. After providing a conductive region, a dielectric layer is formed over the conductive region. The sealing ring includes an L-shaped cross-section that provides an effective seal regardless of the port diameter of the fluid control device, and thus, reduces the number of types of seals required to be stored in inventory for various applications. A user explicitly originates the archive request through the trigger device. The antenna is integral with the lens member. Advantageously, the temperature insensitive optical retarder is simple, easy to construct, can be used for any birefringent crystal and does not require the use of different birefringent crystals.
