Abstract:
A method of performing an oxygen radical enhanced atomic-layer deposition process on a surface of a substrate that resides within an interior of a reactor chamber is disclosed. The method includes forming an ozone plasma to generate oxygen radicals O*. The method also includes feeding the oxygen radicals and a precursor gas sequentially into the interior of the reactor chamber to form an oxide film on the substrate surface. A system for performing the oxygen radical enhanced atomic-layer deposition process is also disclosed.
Abstract:
Provided are systems and processes for forming a three-dimensional circuit on a substrate. A radiation source produces a beam that is directed at a substrate having an isolating layer interposed between circuit layers. The circuit layers communicate with each other via a seed region exhibiting a crystalline surface. At least one circuit layer has an initial microstructure that exhibits electronic properties unsuitable for forming circuit features therein. After being controllably heat treated, the initial microstructure of the circuit layer having unsuitable properties is transformed into one that exhibits electronic properties suitable for forming circuit feature therein. Also provided are three-dimensional circuit structures optionally formed by the inventive systems and/or processes.
Abstract:
Systems and methods for processing a material layer supported by a substrate using a light-source assembly that includes LED light sources each formed from an array of LEDs. The material layer is capable of undergoing a photo-process having a temperature-dependent reaction rate. Some of the LEDs emit light of a first wavelength that initiate the photo-process while some of the LEDs emit light of a second wavelength that heats the substrate. The heat from the substrate then heats the material layer, which increases the temperature-dependent reaction rate of the photo-process.
Abstract:
Laser annealing of a semiconductor wafers using a forming gas for localized control of ambient oxygen gas to reduce the amount of oxidization during laser annealing is disclosed. The forming gas includes hydrogen gas and an inert buffer gas such as nitrogen gas. The localized heating of the oxygen gas and the forming gas in the vicinity of the annealing location on the surface of the semiconductor wafer creates a localized region within which combustion of oxygen gas and hydrogen gas occurs to generate water vapor. This combustion reaction reduces the oxygen gas concentration within the localized region, thereby locally reducing the amount of ambient oxygen gas, which in turn reduces oxidation rate at the surface of the semiconductor wafer during the annealing process.

Abstract:
A method of performing a radical-enhanced atomic-layer deposition process on a surface of a substrate that resides within an interior of a reactor chamber is disclosed. The method includes forming plasma from a gas mixture consisting of CF4 and O2, wherein the CF4 is present in a concentration in the range from 0.1 vol % to 10 vol %. The plasma formed from the gas mixture generates oxygen radicals O* faster than if there were no CF4 present in the gas mixture. The method also includes feeding the oxygen radicals and a precursor gas sequentially into the interior of the reactor chamber to form an oxide film on the surface of the substrate. A system for performing the radical-enhanced atomic-layer deposition process using the rapidly formed oxygen radicals is also disclosed.

Abstract:
Methods of laser processing photoresist in a gaseous environment to improve at least one of etch resistance and line-edge roughness are disclosed. The methods include sequentially introducing first and second molecular gases to the photoresist surface and performing respective first and second laser scanning of the surface for each molecular gas. The first molecular gas can be trimethyl aluminum, titanium tetrachloride or diethyl zinc, and the second molecular gas comprises water vapor. Short dwell times prevent the photoresist from flowing while serving to speed up the photoresist enhancement process.
