Abstract: A double-sided digital lithography or exposure system and method are provided. The system includes a first optical engine 110 for exposing a front side of a substrate 910, a second optical engine 120 for exposing the back side of the substrate 910, a control system 710 for generating a first exposure pattern and a second exposure pattern aligned on the front and back surfaces of the substrate 910 based on the position information of the first optical engine 110 and the second optical engine 120, and controlling the first optical engine 110 and the second optical engine 120 to expose the front and back surfaces of the substrate 910 with the first exposure pattern and the second exposure pattern.

Abstract: A new type of fine metal mask (FMM) used in OLED production and the method of manufacturing it, wherein the FMM includes a frame made of a metal substrate with a plurality of through holes, a layer of fine mask electroformed on the surface of the frame so that said fine mask and said frame are seamlessly integrated, said fine mask is divided into a pattern area and a border area, and the pattern area corresponds to the through holes on the frame, and the method of manufacturing such an FMM comprising the steps of: A. providing a metal substrate by cutting an invar alloy or stainless steel plate to a desired size; B. providing an fine mask by adding a photoresist layer on the metal substrate, exposing a desired pattern onto said photoresist layer, and electroforming a metal base layer and a metal layer with a low thermal expansion coefficient; and C.

Abstract: A maskless exposure system that has multiple maskless optical engines arranged in an (N×M) matrix that form and project a pattern onto a substrate. A first stage system is capable of driving the maskless optical engines in a first direction, a second stage system capable of holding and moving the substrate in a second direction perpendicular to the first direction. A control system that processes data and synchronizing movement of the first and second stage systems and a vision system that detects the positions of the second stage system to synchronize movements with the multiple optical engines.

Abstract: A double-sided maskless exposure system and method consists of light sources which includes two light wavelength segments, maskless optical engines in which a 2D spatial light modulation (spatial light modulator) device, such as DMD, is generating a plurality of pixel array of the pattern, vision system, moving substrate and computer control system. The double-sided maskless exposure system at least includes two maskless optical engines with auto-calibration function which can correct any alignment error in-line. Each optical engine is for each side of the substrate. The optical engines are aligned each other in pairs and are simultaneously patterning on each side of the moving substrate. The system also includes a manipulator for moving, stepping or scanning the optical engines, relative to the substrate so that it can create a contiguous whole image on the both sides of the subject.

Abstract: Pipe cladding is based upon a fiber-reinforced brittle matrix composite material. The coating is isotropic, demonstrating pseudo-strain hardening behavior in uniaxial tension, and damage tolerance by design, not relying on stratified layers of reinforcing mesh embedded within concrete or other brittle cementitious matrices for impact resistance, fracture toughness, or crack width control. The fiber reinforced brittle matrix composite cladding protects both the pipe and inner thin, anti-corrosion layer (if present) from impact or abrasion damage while permitting bending of coated and clad pipe. The finished composite clad can be in a simple circular form alone the pipe or in some complex form providing an integrated housing for electrical or optical fiber cables, or optical sensing sensors for continuous or intermittent sensing of pipeline leakage or failure.
