Used OAI 200 #9008675 for sale

OAI 200, also known as Orion Aligner Mask, is a high resolution image alignment equipment used in semiconductor fabrication process. This system is used to measure and align marks on semiconductors wafers. 200 is composed of an overlay, non-contact optical imaging unit. The machine measures exact pixel-level positions of marks from the overlay grid, created by laser diodes or laser beams. OAI 200 uses high resolution lenses and a multi-axis stage to precisely control orientation and registration of images. The tool consists of a stage control unit and a detection control unit. The stage control unit precisely controls the rotation and tilt of the stage to the desired orientation and position for capturing images. The detection control asset uses electro-optical devices to detect images. It uses either edge detection or center of light detection to capture and align images. 200 model measures overlay images from 200nm to 800nm size and works at both 1x and 4x speed. It is capable of measuring complete areas of the wafer in a single shot. The equipment can measure marks across the image which helps to minimise overcalibration. This enables higher yields of product. The image analysis software used in the system lets users customize their own response functions for the edge detection, circle detection and center of mass detection. In addition, OAI 200 has a real-time image capture unit that allows the user to capture and align multiple images simultaneously. The machine can measure and align multiple areas of a wafer in one iteration. The tool has several advanced features such as automated alignment for multi-die die stacks and multi-bay multi-layer substrates. 200 also offers highly accurate alignment features and accurate alignment results. OAI 200 is ideal for measuring the size of microscopic light sources, quickly measuring small undersized pixels and manufacturing 0.18 microns chips with excellent yield. The asset is used in various industries such as aerospace, automotive, medical, and semiconductors.
