Electro Scientific Industries, Inc., together with its subsidiaries, provides laser-based manufacturing solutions worldwide. The company?s laser systems enable precise structuring of micron to submicron features in components and devices, which are used in various end products in the consumer electronics, computer, communications, and other industries. It offers semiconductor memory yield systems used to manufacture dynamic random access memory devices; traditional silicon wafers; ultrathin silicon wafers used in the three-dimensional packaging applications; sapphire wafer scribing systems used in manufacturing light emitting diodes (LEDs); and laser liquid crystal display repair systems to enhance yields in the manufacture of flat panel displays. The company also produces test and inspection equipment used in quality control process during the production of multilayer ceramic capacitors (MLCCs); laser microvia engineering systems for electrical interconnect applications between layers in high-density circuit boards, and IC packages; and ultraviolet laser processing systems comprising single-beam and multi-beam systems that produce vias for improving yield of packages and substrates. Its laser microfabrication systems allow microelectronics, semiconductor, and other microtechnology manufacturers to physically alter select device features during high-volume production. In addition, the company designs and manufactures products that combine high-speed small parts handling technology with real-time control systems to provide solutions for manufacturers of MLCCs and other passive components, such as capacitor arrays, inductors, resistors, varistors, and hybrid circuits. It sells its products through direct sales and service offices, value-added resellers, and independent representatives. The company was founded in and is headquartered in Portland, Oregon.
