Diazonium salts are also useful as a photosensitive material in a photobleachable two-layer resist system based on a doping process (10). High-resolution resist patterns were obtained using this two-layer resist scheme and an i-line reduction projection aligner. 

CEL dye. A CEL solution was obtained by dissolving poly(N-vinylpyrrolidone) (PVP) (7 g) and Dl (5.8 g) in 50 wt% aqueous acetic acid. (87.2 g). The CEL layer was spin-coated onto a photoresist, RI-7000P (Hitachi Chemical Co.), and baked at 80T for 20 minutes. Exposure was performed with an in-house i-line reduction projection aligner. The resist was developed in a 2. 38 wt% tetramethylammonium hydroxide aqueous solution. The film thickness was measured with an Alpha-step 200 (Tencor)... 

In collaboration with Nexia Solutions, NBA are supporting a series of University Research Alliances (URA) to develop and maintain a network of basic science capability and skills to achieve the short and long-term aims of our mission. Furthermore, the NBA has supported student bursaries, where additional funding has been made available to support PhB projects aligned to the NBA needs, risks and opportunities. Nine awards were made in 06. 

Since large-scale projects required well-organized operations, government officials with either management experience or technical knowledge played leading roles. These officials mainly saw technical projects as political projects aligned... 

Level. Keeping your projects aligned during construction can make the difference between a wobbly step-stool and one you can actually use. As in your domestic repair tool kit (see page 216), choose between a bubble and a laser level.
