Abstract: A high-aspect ratio resist profile is obtained using a development process wherein a mixture of an alcohol and water is used as the developer. The alcohol/water mixture is non-toxic, and does not cause excess swelling and cracking of the resist during the development process.

Abstract: The present invention is directed to a method of forming a new material layer or region near an interface region of two dissimilar materials, and an optional third layer, wherein at least one of said dissimilar materials or optional third is capable of being heated by microwave energy. The method of the present invention includes a step of irradiating a structure containing at least two dissimilar materials and an optional third layer under conditions effective to form the new material layer in the structure. An apparatus for conducting the microwave heating as well as the structures formed from the method are also described herein.

Abstract: The present invention is a method of utilizing microwave energy for annealing of ion implanted wafers. By controlling the time, power density and temperature regime, it is possible to substantially fully anneal the wafer while limiting (and substantially preventing) the diffusion of dopant into the silicon, thereby producing higher performance scaled semiconductor devices. It is also possible, using different conditions, to allow and control the dopant profile (diffusion) into the silicon. Another aspect of the present invention is a method of forming a PN junction in a semiconductor wafer having a profile depth less than about 50 nm and a profile wherein the net doping concentration at said PN junction changes by greater than about one order of magnitude over 6 nm wherein the surface concentration of said dopant is greater than about 1×1020/cm3.

Abstract: An inventive mirror system for use in providing reflected X-ray radiation to a mask having pattern areas and opaque areas, comprising a plurality of parallel mirror segments which are vertically positioned with respect to each other at distances approximately equal to the widths of the corresponding opaque mask areas. In operation, radiation incident on each of the mirror segments is reflected to the patterned feature areas of the mask and skips over the opaque mask areas.

Abstract: A membrane mask structure for lithography using a radiation source and steps for fabricating and using the inventive membrane mask structure. The membrane mask structure comprises the following: a support structure formed of a material which is opaque to the lithographic radiation source and comprising support members separated by window areas; a membrane layer overlaying said support members and window areas, said membrane layer comprised of material which is transparent to said radiation source; and a pattern of feature material formed on or embedded in the membrane layer, said feature material being opaque to the radiation source and said feature pattern aligning with the window areas of said support structure. The mask structure may additionally include a plurality of reference markers formed in or on said membrane layer or on said support members of said support structure.
