Abstract:
Laser annealing methods for integrated circuits (IC) are disclosed. In particular, an upper surface of an integrated circuit is annealed with a laser using a brief burst of light from the laser. In an exemplary embodiment, the brief burst of light from the laser lasts approximately fifty (50) to five hundred (500) microseconds. This brief burst will raise the temperature of the surface to approximately 1200C.
Abstract:
Annealing solutions providing damage-free laser patterning utilizing auxiliary heating to anneal laser damaged ablation regions are provided herein. Ablation spots on an underlying semiconductor substrate are annealed during or after pulsed laser ablation patterning of overlying transparent passivation layers.
Abstract:
n-GaN基板11上に、MOCVD法により、n-Al x Ga 1-x N層12、Al y Ga 1-y Nからなる第1キャップ層2a、およびAl z Ga 1-z Nからなる第2キャップ層2bを順次形成して、被処理基板2を形成する。その後、第2キャップ層2b、第1キャップ層2a、およびn-Al x Ga 1-x N層12に不純物をイオン注入する。イオン注入後に、被処理基板2に対して高温で活性化アニールを行うことによって、n-Al x Ga 1-x N層12からの窒素抜けを抑制しつつ、イオン注入した不純物を活性化させる。活性化アニール後、第2キャップ層2bを塩素系ドライエッチング法により除去し、第1キャップ層2aをKOH水溶液によるウェットエッチング法により除去する。

Abstract:
Embodiments of the disclosure generally relate to a support cylinder used in a thermal process chamber. In one embodiment, the support cylinder comprises a ring body having an inner peripheral surface and an outer peripheral surface, wherein the ring body comprises an opaque quartz glass material and wherein the ring body is coated with an optical transparent layer. The optical transparent layer has a coefficient of thermal expansion that is substantially matched or similar to the opaque quartz glass material to reduce thermal expansion mismatch that may cause thermal stress under high thermal loads. In one example, the opaque quartz glass material is synthetic black quartz and the optical transparent layer comprises a clear fused quartz material.
Abstract:
Methods of forming a semiconductor structure include the use of channeled implants into silicon carbide crystals. Some methods include providing a silicon carbide layer having a crystallographic axis, heating the silicon carbide layer to a temperature of about 300 °C or more, implanting dopant ions into the heated silicon carbide layer at an implant angle between a direction of implantation and the crystallographic axis of less than about 2°, and annealing the silicon carbide layer at a time-temperature product of less than about 30,000 °C-hours to activate the implanted ions.
