    Abstract: In a lead frame board, while a heat radiation wall member formed by a resin having a relatively high thermal conductivity is provided in a low heat-resistance heat generating component mounting region where a low heat-resistance heat generating component is mounted, heat block wall members formed by resins having relatively low thermal conductivities are provided in a high heat-resistance heat generating component mounting region where a high heat-resistance heat generating component is mounted and in a non-heat generating component mounting region where a non-heat generating component is mounted. Thus, heat block is performed between the low heat-resistance heat generating component mounting region and the high heat-resistance heat generating component mounting region and non-heat generating component mounting region, and a heat radiation function is enhanced in the low heat-resistance heat generating component.

    Abstract: Embodiments of the invention relate to a method of functional materials deposition using a polymer template fabricated on a substrate. Such template forms an exposed and masked areas of the substrate material, and can be fabricated using polymer resists or Self-assembled monolayers. Deposition is performed using an applicator, which is fabricated in the shape of cylinder or cone made of soft elastomeric materials or laminated with soft elastomeric film. Functional materials, for example, metals, semiconductors, sol-gels, colloids of particles are deposited on the surface of applicator using liquid immersion, soaking, contact with wetted surfaces, vapor deposition or other techniques. Then wetted applicator is contacted the surface of the polymer template and rolled over it's surface. During this dynamic contact functional material is transferred selectively to the areas of the template. Patterning of functional material is achieved by lift-off of polymeric template after deposition. According to another embodiment, where self-assembled monolayers are used as template, selective deposition of functional materials is achieved either due to low surface energy of SAM or reactivity of terminal groups.

    Abstract: Methods here disclosed provide for selectively coating the top surfaces or ridges of a 3-D substrate while avoiding liquid coating material wicking into micro cavities on 3-D substrates. The substrate includes holes formed in a three-dimensional substrate by forming a sacrificial layer on a template. The template includes a template substrate with posts and trenches between the posts. The steps include subsequently depositing a semiconductor layer and selectively etching the sacrificial layer. Then, the steps include releasing the semiconductor layer from the template and coating the 3-D substrate using a liquid transfer coating step for applying a liquid coating material to a surface of the 3-D substrate. The method may further include coating the 3-D substrate by selectively coating the top ridges or surfaces of the substrate. Additional features may include filling the micro cavities of the substrate with a filling material, removing the filling material to expose only the substrate surfaces to be coated, coating the substrate with a layer of liquid coating material, and removing said filling material from the micro cavities of the substrate.
