Abstract: A method of fabricating a microelectronic die is provided. Transistors are formed in and on a semiconductor substrate. A channel of each transistor is stressed after the transistors are manufactured by first forming a diamond intermediate substrate at an elevated temperature on a handle substrate, allowing the intermediate substrate and the handle substrate to cool, and then removing the handle substrate. The intermediate substrate has a lower coefficient of thermal expansion than the handle substrate, so that the intermediate substrate tends to bow when the handle substrate is removed. Such bowing creates a tensile stress, which translates into a biaxial strain in channels of the transistors. Excessive bowing is counteracted with a compensating polysilicon layer formed at an elevated temperature and having a higher CTE on a side of the diamond intermediate substrate.

Abstract: Damage-resistant coatings are provided on radiation-exposed surfaces of EUV lithographic components. The diamond coating provides resistance to particle impingement, cleaning processes, and degradation due to high temperatures. The diamond coating is beneficial when deposited on the reflecting surface of an EUV Si/Mo multilayer mirror, grazing collector incidence mirror, the reflecting surface of an EUV Si/Mo multilayer reflective mask, and radiation-exposed surfaces of EUV debris shield. The diamond coating provides longer lasting EUV components.

Abstract: A diamond insulator collar and methods for fabricating a diamond insulator collar for electrical discharge gas plasma EUV source. The insulating collar is positioned at the base of the central electrode in the pre-ionization region of the plasma head. The insulating collar prevents electrical shorting between the outer electrode and the central electrode in this region. In one embodiment of a method for providing a wire mesh-reinforced diamond insulator collar, a mandrel is provided that replicates the shape of the base of the central electrode. A wire mesh is wrapped around the mandrel conforming to the shape of the mandrel. The wire mesh is coated with electrically insulating diamond using known plasma enhanced chemical vapor deposition (CVD) techniques to form a non-porous coating. The mandrel is removed from the diamond-coated wire mesh providing a porous-free wire-reinforced diamond insulator collar. Embodiments of non-wire reinforced collars are presented.
