Precision Vision Components for Semiconductor Manufacturing
Advances in semiconductor manufacturing technology are driving the development of higher performance vision systems. With higher vision processing speeds and resolutions, as well as greater hardware and software requirements, new standards such as Camera Link HS, and CoaXPress are being developed. OEM's are taking advantage of these new standards to develop next generation inspection equipment for high-volume wafer production, testing, and packaging. The goal is to reduce inspection time and improve quality, while adapting easily to different wafer sizes.
Capturing defects at each point of the manufacturing process is critical in semiconductor manufacturing. Cameras, frame grabbers, lighting and software all play an important role in the various inspection processes that are conducted during the different steps required to turn silicon into working chips. This environment creates an industry demand for more powerful, higher resolution, higher speed, low light cameras. OEMs in this market are the real technology drivers of the future, and therefore are always seeking state of the art solutions, in order to ensure profitable business results.

Wafer Surface Inspection
Ultra-high-resolution cameras with specialized optics detect microscopic defects, scratches, particles, and contamination on silicon wafer surfaces. Line scan and area scan cameras operating at high speeds inspect entire wafer surfaces, identifying defects measured in nanometers that could compromise chip functionality or yield.
Pattern Defect Detection
Advanced imaging systems verify that photolithography patterns are correctly formed on wafers, detecting missing features, bridging, and dimensional variations. High-resolution sensors and precise optics enable detection of pattern defects at the sub-micron level, ensuring circuit integrity across the entire wafer.
Die Inspection & Sorting
Vision systems inspect individual die for defects, verify proper singulation, and guide pick-and-place equipment for die sorting and packaging. High-speed cameras enable 100% inspection at production rates, maximizing yield by identifying and removing defective die before packaging.
Package & Bond Wire Inspection
Cameras with specialized lighting and high magnification lenses inspect wire bonds, ball bonds, and package integrity. Vision systems detect wire sweep, insufficient bonds, missing wires, and package cracks that could cause device failure, ensuring reliability in finished semiconductor products.
Alignment & Registration
Precision vision systems provide accurate alignment and registration for lithography, bonding, and assembly processes. Sub-micron positioning accuracy ensures proper layer-to-layer alignment and component placement critical to semiconductor device functionality and performance.
Metrology & Dimensional Measurement
High-precision measurement systems verify critical dimensions of features, layers, and structures throughout the manufacturing process. Telecentric optics and high-resolution sensors enable accurate measurement of feature sizes, layer thickness, and dimensional tolerances essential for process control.
