Abstract:
A method is disclosed for forming a micromechanical device. The method includes fully or partially forming one or more micromechanical structures multiple times on a first substrate. A second substrate is bonded onto the first substrate so as to cover the multiple areas each having one or more micromechanical structures, so as to form a substrate assembly. The substrate assembly is then separated into individual dies, each die having the one or more micromechanical structures held on a portion of the first substrate, with a portion of the second substrate bonded to the first substrate portion. Finally, the second substrate portion is removed from each die to expose the one or more micromechanical structures on the first substrate portion. The invention is also directed to a method for forming a micromechanical device, including: forming one or more micromechanical structures in one or more areas on a first substrate; bonding caps onto the first substrate so as to cover the one or more areas each having one or more micromechanical structures, so as to form a substrate assembly; after a period of time, removing the caps to expose the one or more micromechanical structures. During the period of time between bonding the caps and later removing the caps, the substrate assembly can be singulated, inspected, irradiated, annealed, die attached, shipped and/or stored.
Abstract in simplified Chinese:本发明提供用于选择性更新记忆胞数组之记忆胞的方法与设备。该记忆胞数组之各列的记忆胞系设有复数个字符线。该列之记忆胞系由不同的字符线启动与更新。在使用记忆胞数组以控制该显示系统之像素,及利用脉冲宽度调制(PWM)技术以显示灰阶之显示系统应用中,可借由不同PWM波形调制该等像素,借以减少所感知之动态伪轮廓假影(dynamic–false–contouring artifact)。在另一应用中,提供多数字元线能精确地量测由该记忆胞数组之记忆胞维持的电压。

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 packaged micromirror array for a projection display according to the application comprises an array of micromirrors that are capable of movement between an OFF state and an ON state by pulse width modulation to achieve a gray scale image on a target and wherein each micromirror corresponds to a pixel in a viewed image on the target; and a package having a light transmissive window. The array of micromirrors is disposed in the package having the light transmissive window. A viewed image, formed on the target by light reflected from the micromirrors and passed through said mask, has four sides and viewed pixels within the image formed by said micromirrors each have four sides which are not parallel to any sides of the viewed image.
Abstract:
A projection display according to the application comprises an array of micromirrors and a light source for providing light to the array of micromirrors. Each micromirror in the array has a shape defined by a plurality of micromirror sides. Light from the light source is incident on the array of micromirrors during operation. The array of micromirrors has four sides and there are no micromirror sides that are parallel to any array sides.
