Semiconductor device and method of forming the same

Abstract

A semiconductor device and a method of forming the semiconductor device are provided. The semiconductor device may include, but is not limited to, a semiconductor substrate and a third array of semiconductor elements. The semiconductor substrate may include a first array of separate grooves, a second array of separate active regions, and at least an isolating region, the isolating region separating the separate active regions from each other. Each separate groove extends in the separate active region and does not extend over the isolating region. The third array of semiconductor elements is provided on the semiconductor substrate. Each of the semiconductor elements has an electrically conductive portion that is provided in the separate groove. The semiconductor element may be a trench gate transistor, and the electrically conductive portion may be a gate electrode.
