Semiconductor metrology instruments are designed for wafer and thin film in-line inspection after semiconductor processing. Today, semiconductor manufacturing follows very strict standards and must accommodate very small dimensions. The resulting quality control (QC) procedures and semiconductor inspection processes have resulted in the development of high-precision semiconductor metrology instruments. Many of these devices and systems use a combination of laser, optical, and electron beam technologies. As a result, these semiconductor metrology instruments can help improve quality and output at every stage of production. By using semiconductor metrology instruments, manufacturers can facilitate semiconductor inspection, reduce manufacturing costs, and shorten the product development cycle.

There are many different types of semiconductor metrology instruments. Examples include wafer probers, imaging stations, ellipsometers, CD-SEMs, ion mills, C-V systems, and diffractometers. A wafer prober is used to test a semiconductor wafer before it is separated into individual dies or chips. An ellipsometer determines the properties and surfaces of thin films by measuring material characteristics such as layer thickness, optical constants, surface roughness, composition, and optical anisotropy. A critical-dimension scanning electron microscope or CD-SEM is used to ensure the stability of the manufacturing process. A CD-SEM can be used to monitor features such as line, space, and pitch; roundness or concentricity; or depth or sidewall measurements. An ion mill is used to prepare heterogeneous bulk materials when wide areas of material must be uniformly thin. A C-V system measures capacitance versus voltage (C-V) and capacitance versus time (C-t) characteristics of semiconductor devices. A diffractometer analyzes the structure of a substance from the scattering pattern that is produced when a radiation beam strikes the substance.

Suppliers of semiconductor metrology instruments are located across the United States and around the world. They conform to a variety of quality standards and regulatory requirements. In Europe, semiconductor metrology instruments bear the CE Mark to indicate that products conform to appropriate European Union (EU) directives. Groups such as the International Standards Organizations (ISO) also provide guidelines to which suppliers adhere.
