Photonics Spectra Magazine: Spot Cooling Helps Industrial Lasers and Optics Stay on Point


The increasing demand in many end markets for advanced manufacturing systems that are able to increase production and cut costs have positioned laser systems as an important fabrication tool. High-power industrial lasers can generate outputs in excess of 10,000 W when processing thick metals, generating a significant amount of heat not only in the targeted surface but also in the sensitive optics inside the laser. The temperature of these optics needs to be maintained to achieve peak performance for the tool. 





OEM Perspectives: Recirculating Chillers for Semiconductor Metrology & Inspection Systems

Introduction

Semiconductor metrology is critical in the semiconductor fabrication process. The complex nature of semiconductor fabrication now requires multiple test stages in between processing steps. Thin film semiconductor wafers are tested using several techniques including ellipsometry and reflectometry. Sophisticated optical equipment is used to inspect for defects as well as for accurate dimensional measurements. Manufacturers of optical inspection systems must integrate a thermal solution for temperature stabilization of optical components.

Thermoelectric Chillers for Semiconductor Metrology & Inspection Systems

Introduction

The implementation of automated metrology systems has been a key to achieving cost effective semiconductor fabrication. The complex nature of semiconductor fabrication requires multiple tests between processing steps to inspect defects as well as measure dimensional properties including thickness, refractive index, resistivity and stress of the thin films. Because thermal noise can impact the image resolution of sensitive optical components in automated metrology systems, a thermal management system is required.
