Methods and material deposition systems for forming semiconductor layers
Systems and methods for forming semiconductor layers, including oxide-based layers, are disclosed in which a material deposition system has a rotation mechanism that rotates a substrate around a center axis of a substrate deposition plane of the substrate. A material source that supplies a material to the substrate has i) an exit aperture with an exit aperture plane and ii) a predetermined material ejection spatial distribution from the exit aperture plane. The exit aperture is positioned at an orthogonal distance, a lateral distance, and a tilt angle relative to the center axis of the substrate. The system can be configured for either i) minimum values for the orthogonal distance and the lateral distance to achieve a desired layer deposition uniformity using a set tilt angle, or ii) the tilt angle to achieve the desired layer deposition uniformity using a set orthogonal distance and a set lateral distance.

SILICON CARBIDE SEMICONDUCTOR DEVICE AND METHOD OF MANUFACTURING SILICON CARBIDE SEMICONDUCTOR DEVICE
Before formation of gate insulating films, an oblique ion implantation of oxygen into opposing sidewalls of trenches, from a top of an oxide film mask is performed, forming oxygen ion-implanted layers in surface regions of the sidewalls. A peak position of oxygen concentration distribution of the oxygen ion-implanted layers is inside the oxide film mask. After removal of the oxide film mask, HTO films constituting the gate insulating films are formed. During deposition of the HTO films, excess carbon occurring at the start of the deposition of the HTO films and in the gate insulating films reacts with oxygen in the oxygen ion-implanted layers, thereby becoming an oxocarbon and being desorbed. The oxygen ion-implanted layers have a thickness in a direction orthogonal to the sidewalls at most half of the thickness of the gate insulating films, and an oxygen concentration higher than any other portion of the semiconductor substrate.
