    摘要: A basic supercritical solution formulated to include at least one supercritical fluid and a base may be used to quench a photo-generated acid within a photoresist as well as develop the photoresist. The base may be the supercritical fluid in the basic supercritical solution. A super critical fluid is a state of matter above the critical temperature and pressure (Tc and Pc). A basic supercritical solution formulated to include at least one supercritical fluid has a low viscosity and surface tension and is capable of penetrating narrow features having high aspect ratios and the photoresist material due to the gas-like nature of the supercritical fluid.

    摘要: Embodiments of the invention provide a non-chemically amplified photoresist, which results in reduced line wide roughness (LWR). In accordance with one embodiment the photoresist includes a developer-soluble resin (DSR) and a photoactive compound (PAC). For one embodiment of the invention, the even distribution of the PAC within the DSR results in reduced acid diffusion thus reducing LWR. Prior to exposure to the light source, the PAC inhibits solubility of the DSR in the developer. Upon exposure the PAC converts to acid to promote solubility of the DSR. The even distribution of the PAC within the photoresist results in reduced LWR and a reduction in defects. For one embodiment the photoresist is applied in the EUV technology (e.g., wavelength is 13.4 nm). For such an embodiment the LWR may be reduced to less than 1.5 nm allowing for effective fabrication of devices having feature sizes of approximately 15 nm.

    摘要: Embodiments of the invention provide methods and compositions for providing photoresists with improved liquid-contact properties. For one embodiment of the invention, a photoresist is provided having one or more constituent components that are resistant to diffusion between the photoresist and an index-matching liquid (IML). For such an embodiment in which the IML is water, a photoresist component is provided that is hydrophobic thus reducing diffusion between the photoresist and the water. In various alternative embodiments of the invention, a photoresist is provided having one or more constituent components that encourage diffusion between the photoresist layer and the IML in such manner as to impart beneficial liquid-contact properties to the photoresist layer. For such an embodiment in which the IML is water, a photoresist is provided having one or more hydrophilic constituents.

    摘要: A series structure of a chemically amplified negative tone photoresist that is not based on cross-linking chemistry is herein described. The photoresist may comprise: a first aromatic structure copolymerized with a cycloolefin, wherein the cycloolefin is functionalized with a di-ol. The photoresist may also include a photo acid generator (PAG). When at least a portion of the negative tone photoresist is exposed to light (EUV or UV radiation), the PAG releases an acid, which reacts with the functionalized di-ol to rearrange into a ketone or aldehyde. Then new ketone or aldehyde is less soluble in developer solution, resulting in a negative tone photoresist.

    摘要: Numerous embodiments of a method to increase the mechanical strength of a photoresist structure are described. In one embodiment of the present invention, a photoresist material is dispensed over a substrate to form a photoresist layer. The photoresist material is exposed to a first radiation treatment to define a pattern to be formed on the photoresist layer. A developer solution is applied to the photoresist material to form the pattern and rinsed with a rinse solution to remove the developer solution. The photoresist material is exposed to a second radiation treatment to induce cross-linking.
