Embodiment Construction

[0033] A clean room, as used in microelectronics, has a plurality of graded areas with corresponding clean room classes. The clean room (class 10 and higher) is therefore surrounded by a separate area with the systems required for coating and structuring, in which the substrates are processed. The pumps required for vacuum technology are usually located in the substratum.

[0034] The access to the clean room is usually reached via a sequence of different clean room regions with descending clean room classes. A change of clothing is often required between different areas. To minimize contamination from things that come into contact with the floor, such as shoe soles, there are special sticky mats at each entrance. In addition to the entrance to the cleanroom itself via an airlock acting on people and materials, inside said airlock, in turn, a powerful air flow and filter system are swirled up and the particles present are drawn out so that no additional pollutants come from ...

Abstract

Disclosed are a method and an apparatus for orienting thin glass plates (11) in a contamination-free manner. Said method and apparatus have the following features: a) in order to orient the glass plate (11), a lifting frame (1) is raised from below through the free space between the rolls (13) along with an orienting frame (2) which rests on the lifting frame (1) and is fitted with struts (7) that are connected in a rotatably hinged fashion to the orienting frame (2) and are provided with supporting elements (8) which penetrate the free space between the rolls (13), project beyond the supporting level of the rolls (13), and support the glass plate (11); b) the glass plate (11) is placed in a shock-free manner by means of sliding elements (3) that are actuated by individually controllable drive units (4), the movement of the sliding elements (3) being transmitted to the two longitudinal cross beams of the orienting frame (2) by means of pivot joints (6) which are fastened to the sliding elements (3).

Description

Background technique [0001] In the production of a large number of large flat screens, the production and further processing of crystal plates are increasingly required. [0002] Modern flat screens are increasingly replacing traditional CRT monitors and are getting cheaper. These rely on TFT / LCD technology. In this article, LCD (Liquid Crystal Display) refers to the use of liquid crystals in the individual pixels of the screen, and TFT stands for Thin Film Transistor. TFTs are very small transistor elements that control the orientation of liquid crystals, and therefore light transmission. [0003] Flat screen displays include many pixels. Each pixel consists of 3 LCD cells (sub-pixels), which in turn correspond to the colors red, green and blue. A 15-inch screen (measured diagonally) includes about 800,000 pixels or about 2.4 million LCD cells. [0004] Understanding of working mode: [0005] Liquid crystal cells (LCD cells) work in a similar way to polarized sunglasses...
