Abstract in simplified Chinese:本发明揭示一种空间光调制器与一种用以制造至少包含一数组微镜设备的调制器之方法。相邻微镜之间的中心至中心距离与间隙系对应于所使用光源而被决定,借以最优化光学效率与性能品质。微镜设备至少包含一形成于一基材上之枢纽支撑件与一被该枢纽支撑件所保持住之枢纽。一镜板借由一接触件连接至该枢纽,且镜板与枢纽间之距离系根据镜板所希望的最大旋转角度、相邻微镜之间的最佳间隙与间距而被决定。于一制造该空间光调制器的方法中,系沉积一牺牲层于一基材上,接着形成一镜板,且沉积另一牺牲层于该镜板上,之后又形成枢纽支撑件。该两牺牲层系经由相邻微镜设备之小间隙而以自发性气相化学蚀刻剂移除。本发明亦揭示一投射系统,其至少包含一空间光调制器、一光源、聚光光学设备(其中来自光源之光线聚集至微镜数组上)、投射光学设备(其系用以选择性投射由微镜数组反射之光线至一目标上)与一控制器(其系用以选择性启动数组中之微镜)。
Abstract in simplified Chinese:本发明揭示一种以一特定自发式蒸气相蚀刻物来移除微结构制造过程中之牺牲材料的方法。在此方法中,一定量的蚀刻物系被喂入一蚀刻室中以移除该牺牲材料。依据所侦测到的蚀刻物量或蚀刻产物量来调整并喂入蚀刻室中之蚀刻物的量来维持蚀刻室中该牺牲材料的蚀刻速率几乎为恒定。因此,本发明提供一种依据所揭示方法来移除牺牲材料的蚀刻系统。

Abstract:
The micromirror device of the present invention comprises a reflective deflectable mirror plate and an addressing electrode provided for deflecting the mirror plate, wherein the addressing electrode is displaced along a direction perpendicular to the length of the hinge such that a portion of the addressing electrode is extended beyond the mirror plate.
Abstract:
A spatial light modulator (100) having a substrate (110) holding an array of deflectable (e.g. mirror) elements (120). The deflectable elements (120) are deflectably coupled to the substrate (110) via corresponding hinges (134), each hinge (134) being disposed on a side of the deflectable element (120) opposite to the side on which the substrate (110) is disposed. By placing the hinge (134) in this way the fill factor of the array is improved. The hinge (134) can be provided flush against the deflectable element (120), or it can be provided with a gap between the deflectable element (120) and the hinge (134). The hinge (134) can be attached via one or more posts (136, 138) or walls connecting to the substrate (110), and with a flexible or deformable portion that is substantially or entirely hidden from view then viewed through the substrate (110) (e.g. a glass substrate). In one embodiment, the hinge (134) is connected to the undersides of both the substrate (110) and the deflectable element (120), and connects towards a center part of the deflectable element (120). In this way, a longer hinge (134) is provided thus reducing strain on any one part of the hinge (134).
