| 99 | Apparatus for uniformly illuminating a light valve | US267125 | 1994-06-28 | US5625738A | 1997-04-29 | Simon Magarill |
| The present invention relates to an optical system for providing uniform illumination of a light valve. The light source is an extended source generally emitting a non-uniform spatial distribution of light power. Source light is focused into the entrance end of a light transmitting tunnel having reflecting interior wall surfaces and having cross sectional and length dimensions chosen to deliver, at the exit end of the tunnel, light which is substantially uniform in power distribution over the surface area of the exit end. This is caused by multiple reflections from the tunnel walls. The exiting light is advantageously used to illuminate uniformly a light valve. The tunnel may be tapered to alter the exit angular aperture. The tunnel may be hollow or filled with a transparent material. In addition, the tunnel may be segmented and folded to provide a joint which conforms tunnel geometry to given spatial limitations between source and valve. The joint also provides a convenient way of directing heat out of the tunnel structure. One embodiment of the present invention includes a compound light transmitting tunnel with a plurality of segments and exit ends. A joint between adjacent segments divides light into a transmitted range of wavelengths and a reflected range of wavelengths. | ||||||

| Fine, sub-micron line features and patterns are created in a radiation sensitive resist layer on a semiconductor wafer by a beam of short wavelength gamma rays. The resist layer includes photoresist which is substantially chemically inactive in response to the gamma rays. The photoresist is either doped or covered with a material that absorbs gamma rays and in response emits secondary radiation of a different wavelength, preferably photons, that is actinic with respect to the photoresist. The resist layer enables using radiation sources having better resolving ability than conventional photolithographic sources to perform near-field and direct-write lithography. | ||||||
