The present invention lengthens gate conductors used in memory chips to limit leakage current, while still allowing the overall size of cells to remain the same. The channel length for each gate is increased by decreasing the size of spaces between gates. Decreases in space size occurs by using photolithographic image enhancement techniques. These techniques allow the space between gate conductors to be smaller while the gate size increases. In addition, a groove may be added that additionally lengthens the effective channel length and provides an additional electrical shield to limit leakage current. These techniques lead to the same density memory cells for a given process with less leakage. Finally, if grooved gate structures are used, having a longer gate conductor allows a three sigma process to be used, which increases yields.

An illumination optical system having a more simplified structure forms various quadrupole-shaped secondary light sources with two-time rotational symmetry with respect to an optical axis. The apparatus can provide illumination conditions that differ in two perpendicular directions on a radiation-receiving plane. In order to form a secondary light source with a quadrupole-shaped light intensity distribution on an illumination pupil plane, a diffractive optical device is provided in which an entrance light beam is converted into four light beams, and a light beam having a shape of four points centered about the optical axis is formed in a far field. The diffractive optical device is provided with a first diffractive optical member that is rotatable about a first axis parallel to the optical axis, and a second diffractive optical member that is rotatable about a second axis parallel to the optical axis, and that is arranged adjacent to the first diffractive optical member. A refractive optical device having first and second refractive optical members accomplishes similar results.

A negative pattern is formed by applying a resist composition onto a substrate, exposing the resist film, and developing the exposed resist film in an organic solvent developer.

A window assembly according to various embodiments includes a frame, a sash, an insulating unit (e.g., one or more glass panels), a glass stop, an elongated frame insulating element slidably disposed on an inner surface of the frame, an elongated sash insulating element slidably disposed on an outer surface of the sash, and an elongated inner sash insulating element slidably disposed on an inner surface of the sash. The elongated frame insulating element, the elongated sash insulating element, and the elongated inner sash insulating element each define a plurality of chambers that extend substantially parallel to a longitudinal axis of each element. These chambers reduce the size of the space between the frame and sash and the size of the space between the sash, the insulating unit, and the glass stop, which results in smaller convection currents within these spaces and a more thermally efficient window assembly.
