20090191474 | ON-TRACK PROCESS FOR PATTERNING HARDMASK BY MULTIPLE DARK FIELD EXPOSURES - This invention provides methods of creating via or trench structures on a developer-soluble hardmask layer using a multiple exposure-development process. The hardmask layer is patterned while the imaging layer is developed. After the imaging layer is stripped using organic solvents, the same hardmask can be further patterned using subsequent exposure-development processes. Eventually, the pattern can be transferred to the substrate using an etching process. | 07-30-2009 |

20100255412 | Photo-imaging Hardmask with Negative Tone for Microphotolithography - Disclosed is a method of making polysiloxane and polysilsesquioxane hardmask layer photo-imageable with a negative tone. The method is based on a photosensitizer and film modifier. The film modifier reduces pore size of the hardmask films for diffusion control. The negative-tone photo-imageable hardmask is especially beneficial for forming trenches and vias on exposure tools of extreme UV and deep UV lithography. Compositions of negative-tone photo-imageable hardmask based on the chemistry of polysiloxane and polysilsesquioxanes are disclosed as well. Further disclosed are processes of using photo-imageable hardmasks to create isolated trenches or vias on semiconductor substrates with or without an intermediate layer. | 10-07-2010 |
20100261097 | Photo-imageable Hardmask with Positive Tone for Microphotolithography - Disclosed are the deactivation mechanism and chemistry platforms that make high-silicon hardmask films photo-imageable like positive-tone photoresist for microphotolithography. The deactivation mechanism requires a catalyst to promote crosslinking reactions, and a photoacid generator to deactivate the catalyst. The initial hardmask films are soluble in developers. If not radiated, films become insoluble in developers due to crosslinking reactions promoted by catalyst. If radiated, films remain soluble in developers due to deactivation of catalyst by photoacid generator. Compositions of positive-tone photo-imageable hardmask based on the chemistry of polysiloxane and polysilsesquioxanes are disclosed as well. Also disclosed is a method of modifying polysiloxane and polysilsesquioxane films for controlled diffusion of catalysts, photoacid generators, and quenchers. Further disclosed are processes of using photo-imageable hardmasks to create precursor structures on semiconductor substrates with or without an intermediate layer. | 10-14-2010 |
20120202349 | Photo-imageable Hardmask with Dual Tones for Microphotolithography - Disclosed is a method of making polysiloxane and polysilsesquioxane based hardmask respond to radiations with positive tone and negative tone simultaneously. Unradiated films are insoluble in developers, showing positivity tone. Radiated films are insoluble in developers as well, showing negative tone. Only half-way radiated films are soluble in developers. The dual-tone photo-imageable hardmask produces splitted patterns. Compositions of dual-tone photo-imageable hardmask based on the chemistry of polysiloxane and polysilsesquioxanes are disclosed as well. Further disclosed are processes of using photo-imageable hardmasks to create precursor structures on semiconductor substrates with or without an intermediate layer. | 08-09-2012 |
