Provided is an arctic drill ship an arctic drill ship which includes a weather tight structure protecting a drill floor from air, and a side strake supporting the weather tight structure around a drilling work area. during film formation by adding active hydrogen and nitrogen oxide to reduce the carbon content during the film formation, and the effect of blocking impurities such as alkali metals is improved. The system maps this vector instruction onto the thread contexts of the multi-threaded microprocessor. By doing so, the needle member tip is caused to vibrate to rub the wafer surface, thereby performing the polishing. Other embodiments are described and claimed.
