Some different aspects of Metrology

1. "Metrology is the science of measurement, including theoretical and experimental conclusions at any level of uncertainty in every area of science and technology." Without a doubt, metrology is the foundation of all practical scientific endeavors. Metrology is crucial because of practically every aspect of daily life—including practical science, technology, and engineering. It also consists of the measurements whether it’s video measurements, wire loop heightmeasurements, Die location measurements, or Die shift measurements. Let’s give a broad look at some features of Optical metrology. Why Wire loop height measurement is important in metrology? A technique and a tool for wire loop height measurements are provided by the invention. The measurement point on the wire loop is placed over a height gauge device. The density of wires used to attach an integrated circuit (IC) chip to a lead frame or packaging board is growing as electronic equipment gets thinner. Multiple chips that are stacked in a package are now connected via a method called wire bonding. In order to help ensure that IC chips fit into packaging as small as a few millimeters thick, it is crucial to control the height and shape of the wire loops that are created during wire bonding. The height gauge device emits incident light to illuminate the location. The height gauge device receives the reflected light created by the incident light, and a processor connected to the height gauge device estimates the height of the said point in relation to a reference surface using a characteristic of the reflected light.

2. Are Multiple Chip Modules uniquely challenging the Metrology? An electrical package made up of several integrated circuits (ICs) put together into one unit is called a multi-chip module (MCM). A Multiple Chip Module can handle a full function and functions as a single unit. The substrate on which the various Multiple Chip Module components are installed is attached to the surface of the substrate's bare dies using wire bonding, tape bonding, or flip-chip bonding. Due to the need to precisely control numerous different factors for multiple die on a common substrate, such as die location measurement, die height at the corners, verification of wire counts for each die, and die-to-substrate alignment characteristics, the inspection of multi-chip modules (MCM) can frequently present particularly difficult metrology requirements. A compact, high-accuracy dimensional metrology system The Important metrology features needs a compact, high-accuracy dimensional metrology system that includes adaptable optics and lighting as well as cutting-edge edge detection and image processing capabilities because of the variety of die types, dimensions, and placements as well as die shift measurements reflection and texture changes between die and substrate surfaces. In addition, attaining the necessary balance of accuracy and throughput can depend on various stage sizes and high-precision movements. Die Shift Measurement is well suited to measuring a wide variety of parts, such as molded plastic parts, machined parts, electronic assemblies, semiconductor packages, fiber optic components, disc media substrates, recording head dies, or semiconductor wafers up to 150 mm in diameter. Process Control - Key Metrology The capacity to read in different CAD file formats, the programming flexibility to quickly measure a broad variety of aperture sizes, shapes, and placements, as well as monitoring for clogged/missing apertures, are key metrology needs for stencil process control.
