    摘要: Apparatus and method for control of epitaxial growth temperatures during manufacture of light emitting diodes (LEDs). Embodiments include measurement of a substrate and/or carrier temperature during a recipe stabilization period; determination of a temperature drift based on the measurement; and modification of a growth temperature based on a temperature offset determined in response to the temperature drift exceeding a threshold criteria. In an embodiment, a statistic derived from a plurality of pyrometric measurements made during the recipe stabilization over several runs is employed to offset each of a set of growth temperatures utilized to form a multiple quantum well (MQW) structure.

    摘要: A retaining ring for use with electrochemical mechanical processing is described. The retaining ring has a generally annular body formed with a conductive portion and a non-conductive portion. The non-conductive portion contacts the substrate during polishing. The conductive portion is electrically biased during polishing to reduce the edge effect that tends to occur with conventional electrochemical mechanical processing systems.

    摘要: An apparatus and method for planarizing a surface of a substrate using a chamber separated into two parts by a membrane, and two separate electrolytes is provided. The embodiments of the present invention generally provide an electrochemical mechanical polishing system that reduces the number of defects found on the substrate surface after polishing. An exemplary electrochemical apparatus includes a physical barrier that prevents any trapped gas or gas generated during processing from residing in areas that can cause defects on the substrate. The process can be aided by the addition of various chemical components to the electrolyte that tend to reduce the gas generation at the cathode surface during the ECMP anodic dissolution process.
