International Classification:

G02F 11335

US Classification:

359 42

Abstract:

The present invention includes a polarizer element and an array of tapered waveguides in substantial contact with the polarizer element. The tapered end of each of the waveguides extends outward from the polarizer element. Each of the waveguides has a light input surface adjacent the polarizer element and a light output surface distal from the light input surface. The area of the light input surface of each of the waveguides is greater than the area of its light output surface. Also, the waveguides in the array are separated by interstitial regions with a lower refractive index than the refractive index of the waveguides. The present improved polarizer may be used in display devices, such as projection display devices, off screen display devices, and direct view displays. Such displays are used in a wide range of applications including computer terminals, airplane cockpit displays, automotive instrument panels, televisions, and other devices that provide text, graphics, or video information.

Abstract:

A method for producing a negative image by coating a substrate with a photosensitive layer containing a blocked hydrophobic polymer capable of deblocking in the presence of an acid, and an oxime sulfonate ester or o-quinone-4-sulfonyl-containing diazide, then imagewise exposing, treating with a gaseous base, removing excess base, overall flood exposing, baking and developing with an aqueous alkaline solution.

Karl W. Beeson - Princeton NJ
Scott M. Zimmerman - Basking Ridge NJ
Paul M. Ferm - Morristown NJ
Michael J. McFarland - Washington NJ

Assignee:

AlliedSignal Inc. - Morristown NJ

International Classification:

B29D 1100

US Classification:

264 127

Abstract:

The present invention is directed to a process for making an array of tapered photopolymerized waveguides. A photomask having opaque and transparent regions is placed in substantial contact with a substrate having a substantially uniform thickness of photopolymerizable mixture thereon. The photopolymerizable mixture is then exposed through the transparent regions of the photomask to substantially collimated actinic radiation for a time sufficient to form an array of tapered photopolymerized waveguides. The photomask and photopolymerizable mixture which was not substantially polymerized by the substantially collimated actinic radiation are then removed from the substrate. The tapered waveguides are useful as a display means in direct view devices and projection display devices.

Assignee:

Allied Corporation - Morristown NJ

International Classification:

G03C 160
G03C 1495

US Classification:

430192

Abstract:

A novel positive photoresist formulation is provided based on a 1:1 copolymer of maleimide and an aliphatic vinyl ether or ester in combination with a photoactive sensitizer capable of undergoing a change in aqueous alkaline solubility upon exposure to actinic radiation. The copolymers disclosed have structures of the following type: ##STR1## where R is an alkyl substituent of from 1 to 20 carbon atoms, benzyl, C. sub. 1 to C. sub. 10 aralkyl, C. sub. 3 to C. sub. 12 cycloalkyl or ##STR2## where R" has the structures assigned to R, and where R' is independently H, C. sub. 1 to C. sub. 10 alkyl, phenyl, benzyl or C. sub. 1 to C. sub. 10 aralkyl. The polymers are compounded with a photoactive sensitizer capable of undergoing a change in aqueous alkaline solubility upon exposure to actinic radiation such as with diazonaphthoquinone sulfonic acid esters and amides. The polymer and sensitizer compositions are dissolved together in a solvent useful for spin casting of thin films on substrates.

Inventors:

Michael J. McFarland - Bound Brook NJ

Assignee:

Hoescht Celanese Corporation - Somerville NJ

International Classification:

G03C 516

US Classification:

430325

Abstract:

A positive acting photoresist system including a hydrophobic blocked polymer can be made to function in a negative sense (or tone) in what is known as an "image reversal" process, which may be summarized as follows: (1) After being exposed to UV radiation through a mask pattern to produce photogenerated acid, a photoresist coated wafer is treated with a gaseous base such as ammonia. The base reacts with photogenerated acid to produce a salt, effectively preventing deblocking of the polymer. (2) The wafer then is exposed to a vacuum to remove any excess base. (3) The wafer is then flood-exposed (i. e. , no mask is used) with UV light. This produces acid in the previously masked-over areas. The sensitizer has already been largely destroyed in the original image area and so little acid is produced there. (4) The wafer is then baked to deblock the polymer in the area not exposed in step (1) and developed in aqueous alkali.
