A novel radiation detector, a detection principle and an associated structure are provided for semiconductor substrate detectors in general and for CMOS based circuits in particular. For an optical detector, photons absorbed in the neutral zone of the substrate generate electron hole pairs that migrate by diffusion. A shadow mask gives a spatial modulation to the incident, and consequently, to the absorbed light in the semiconductor substrate. By measuring the magnitude of the spatial frequency component in the minority carrier distribution with a spatial frequency corresponding to that of the shadow mask, a fast detector is conceived. A shadow mask with higher spatial modulation frequency delivers a faster turn-off. The combination of a plurality of these detectors with an image fiber forms a basic system for constructing high-speed parallel optical interconnects between chips.

This allows the second annulus to always be formed inherently and precisely substantially coaxial with the first annulus. Moreover, the second annulus can be formed with a much greater tolerance than if other independent components needed to be added.

Nitroxide mediated free radical polymerization of vaporized vinyl monomers, including acrylic acid (AAc), styrene (St), N-2-(hydroxypropyl)methacrylamide (HPMA) and N-isopropyl acrylamide (NIPAAm), on silicon wafers is demonstrated. FTIR, ellipsometry and contact angle goniometry were used to characterize the chemical structures, thickness and hydrophilicity of the films. The growth of film is linearly proportional to its reaction time, leading to the easy and exact control of polymer film thickness from nanometers to submicrons.
