Author: Steven Chen, Process Control Solutions Technologist, KLA-Tencor Corporation Introduction LED manufacturing is undergoing a tremendous transformation.  The evolution to high brightness LED, larger wafer size and new complex architectures make LED manufacturing more challenging than ever before.  Even though these trends greatly benefit the advancement of the LED industry in terms of LED efficiency and performance, they can also potentially negatively impact yield.  In order for LED manufacturers to stay competitive in this dynamic environment, they need to have a comprehensive in-line process control strategy to improve the yield to make the solution cost effective. Currently, most LED manufacturers rely on inspection tools to inspect and provide defects of interest (DOI).  Defect density is typically utilized as the gauge for statistical process control (SPC) control.  However, the drawback of this approach is the fact that there can potentially be a lot of nuisance defect that does not cause yield loss.  In looking at a defective wafer through an inspection tool, how do you determine which defects are killer defects that impact the yield or electrical performance, and which defects are nuisance?  How can killer defects be detected at the earliest possible time to prevent costly excursions?  These are the questions that must be addressed properly.

In the next years, the use of PSS will further increase due to its high light extraction efficiency. Following this trend, LayTec‘s in-situ metrology software EpiNet 2 can be individually customized for various kinds of PSS. Our users can expand the substrate database by themselves. LayTec‘s Calibration Manual explains how to measure PSS reflectance in different pockets in one single calibration run. If required, LayTec also offers related customer trainings. Once the initial reflectance values of the PSS substrates are uploaded, the operator can choose the needed substrate in the RunType‘s Material Spec window (Fig. 1). As a result, all PSS wafers can be monitored with the same accuracy as standard sapphire substrates.

A major challenge of in-situ metrology on single-port reactors with small viewport geometries is the combination of curvature measurements by a blue laser with reflectance measurement at 405 nm. The blue laser is a must for patterned sapphire substrates (PSS) and double-side polished substrates.  The 405 nm reflectance is indispensable for monitoring of InGaN MQW growth. Until now, it was impossible to have both features for reactors with only one small optical access because of the cross-talk effect. The new optical and electronic design of EpiCurve® TT eliminates this problem.
