US Patent:

20070048966, Mar 1, 2007

Filed:

Mar 9, 2006

Appl. No.:

11/373630

Inventors:

Hoang Le - San Jose CA, US
Kuo-In Chen - Los Altos CA, US

International Classification:

H01L 21/76

US Classification:

438424000

Abstract:

Systems and methods for narrow semiconductor trench structures. In a first method embodiment, a method for forming a narrow trench comprises forming a first layer of insulating material on a substrate and creating a trench through the first layer of insulating material and into the substrate. A second insulating material is formed on the first layer and on exposed portions of the trench and the second insulating material is removed from the first layer of insulating material and the bottom of the trench. The trench is filled with an epitaxial material and the first layer of insulating material is removed. A narrow trench is formed by the removal of remaining portions of the second insulating material.

International Classification:

H02K 3/28

Abstract:

An electric motor comprises a stator and a rotor having a specified number of rotor poles that magnetically interact with the stator so as to rotate in relation to the stator. The stator is a slotted stator with a specified number of stator poles with slots between those poles and is provided with a set of conductive windings that are fitted into the slots and wound around the stator poles according to a specified pattern. The motor has a single-layer winding configuration, wherein there are one or more empty stator poles without windings on each side adjacent to those stator poles with a winding, so that only one set of windings is present in each slot. Stator poles with a winding terminate in a stator shoe, while stator shoes are absent from each empty stator pole, thereby expanding the gap for machine winding into the slots.
