Method of forming a barrier layer of a tunneling magnetoresistive sensor

A fabrication process for a tunneling magnetoresistance (TMR) sensor is disclosed. In particular, a unique method of forming a barrier layer of the TMR sensor is utilized so that the TMR sensor exhibits good magnetic and TMR properties. In one particular example, the barrier layer is formed by depositing a metallic film in an argon gas in a DC magnetron sputtering module, depositing an oxygen-doped metallic film in mixed xenon and oxygen gases in an ion-beam sputtering module, and oxidizing these films in an oxygen gas in an oxygen treatment module. This three-step barrier layer formation process minimizes oxygen penetration into ferromagnetic (FM) sense and pinned layers of the TMR sensor and optimally controls oxygen doping into the barrier layer. As a result, the FM sense and pinned layers exhibit controlled magnetic properties, the barrier layer provides a low junction resistance-area product, and the TMR sensor exhibits a high TMR coefficient.

Protective coating system for reflective optical elements, reflective optical element and method for the production thereof

A limiting factor in the operation of EUV lithographic devices is the lifetime or the reflectivity of the reflective optics that is reduced by contamination with carbon-containing substances. Protective coatings that are resistant to oxidation or are inert against water are already known. According to the invention it is proposed to deposit protective coatings on, for example, multilayers that suppress the growth of carbon-containing substances in combination with layers that are inert against residual gas atmosphere and energy input. Even with a long operating time a high reflectivity is thereby retained. The protective coatings may be deposited by electron-beam vaporization, magnetron- or ion-beam sputtering.
