Light-controlled manufacturing of semiconductor structures: a platform for next generation processing of photonic devices

Platform Grant(PG)将应用我们在结构照明和无机/有机混合半导体光电器件方面的国际领先专业知识，在快速发展的光控制造领域创造新的机遇。原则上可以从无机(GaN)和有机LED获得结构化照明场，通过继电光学在宏观尺度上实现，或将其消磁到微尺度。光聚合材料的新制造可以首先涉及使用结构照明作为一种控制机动阶段的新方法。这项技术可以与用于无掩模光刻图案化、在更大范围内连续光固化、局部光化学沉积或其他形式的光不稳定组装的图案可编程UV激发相结合。也可以设想不同的工艺，其中任意位置的荧光物体或标记被‘猎杀’，然后经受用于光固化的光束激发或定向光激发。例如，这种方法可以用来固定单个胶体量子点，作为量子技术应用中的发射器。具有传感能力的多功能设备，如用于爆炸物检测的有机激光，是在远程条件下运行的自动化设备的另一个优秀例子。这项技术设想用途的其他例子包括：[1]用于管理高价值物品(艺术品、核燃料容器)的LED微型显示器资产标签。[2)包含独特的荧光物体微图案的无源资产标签(例如。用于更大批量防伪应用的胶体量子点、有机大分子)。[3]用于精细化工制造的可定制连续流动微反应器。[4]为其他自主微系统提供动力的能量收集微模块，其中我们将重点研究有机光伏和环境辐射(RF)方法。

This Platform Grant (PG) will apply our internationally-leading expertise in structured illumination and hybrid inorganic/organic semiconductor optoelectronic devices to create new opportunities in the rapidly developing field of light-controlled manufacturing. Structured illumination fields can in principle be obtained from both inorganic (GaN) and organic LEDs, implemented on a macroscale via relay optics, or demagnified to a microscale. Novel manufacturing with photopolymerisable materials can firstly involve use of structured illumination as a novel means to control motorised stages. This technique can be combined with pattern-programmable UV excitation for mask-free photolithographic patterning, continuous photo-curing over larger fields, localised photochemical deposition, or other forms of photo-labile assembly. Process variants can also be envisaged in which arbitrarily positioned fluorescent objects or markers are 'hunted', and then subject to beam excitation for photocuring or targeted photoexcitation. This method could be used, for example, to immobilise individual colloidal quantum dots for use as emitters in quantum technology applications. Multifunctional devices with sensing ability, such as organic lasers for explosives detection, represent another excellent example of automated devices operating under remote conditions. Further examples of the envisaged uses of this technology include:[1] LED microdisplay asset tags for management of high-value objects (artworks, nuclear fuel containers).[2] Passive asset tags containing unique micro-patterns of fluorescent objects (eg. colloidal quantum dots, organic macromolecules) for higher-volume, anti-counterfeiting applications.[3] Customisable continuous-flow micro-reactors for fine chemical manufacturing.[4] Energy harvesting micro-modules to power other autonomous microsystems, where we will focus on organic PV and ambient-radiation (RF) approaches.
