    Abstract: Plasma nitridation, in place of plasma oxidation, is used for the formation of a CCP layer. Al, Mg, Hf, etc. all form insulating nitrides under these conditions. Maintaining the structure at a temperature of at least 150° C. during plasma nitridation and/or performing post annealing at a temperature of 220° C. or higher, ensures that no copper nitride can form. Additionally, unintended oxidation by molecular oxygen of the exposed magnetic layers (mainly the pinned and free layers) is also avoided

    Abstract: This disclosure concerns methods for fabrication of integrated high speed optoelectronic devices. In one example of such a method, a device region that includes a top surface and a bottom surface is formed on a top surface of a substrate. The device region may take the form of an optical emitter, such as a VCSEL, or a detector, such as a photodiode. Next, an isolation region is formed that is configured such that the device region is surrounded by the isolation region. A superstrate is then disposed on the top surface of the device region. Finally, a micro-optical device, such as a lens, is placed on a top surface of the superstrate.

    Abstract: Methods for sealing or passivating the edges of chips such as vertical cavity surface emitting lasers (VCSEL) is disclosed. One method includes oxidizing the edges of die at the wafer level prior to cutting the wafer into a plurality of die. This may be accomplished by etching a channel along the streets between die, followed by oxidizing the channel walls. The oxidation preferably oxidizes the aluminum bearing layers that are exposed by the channel walls inward for distance. Aluminum bearing layers, including AlAs and AlGaAs, may be oxidized to a stable native oxide that is resistant to further oxidation by the environment. After oxidation, the wafer can be cut along the channels into a number of die, each having a protective oxide layer on the side surfaces.
