Title:
METHOD FOR PRODUCING ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2004/012012
Kind Code:
A1
Abstract:
When the accuracy required for the dimensions of semiconductor circuit pattern approaches the molecular size of resist as the pattern becomes finer, device performance deteriorates due to edge roughness of the resist pattern to have an adverse effect on the system performance. This problem is solved by employing supermolecules having smaller dimensions than those of conventional polymer as a principle component, making the number of reactions required for molecular solubility variation constant and as large as possible, and increasing the acid catalyst density by including an acid generating agent in the supermolecule or bonding the acid generating agent thereto. A pattern of molecular accuracy can thereby be formed with high productivity even for the pattern dimension of 50 nm or less and a high performance system can be realized.
