Abstract:
Antireflective compositions characterized by the presence of an SiO-containing polymer having chromophore moieties and transparent moieties are useful antireflective hardmask compositions in lithographic processes. These compositions provide outstanding optical, mechanical and etch selectivity properties while being applicable using spin-on application techniques. The compositions of the invention are advantagously useful with shorter wavelenght lithographic processes and/or have minimal residual acid content.
Abstract:
An attenuating embedded phase shift photomask blank that produces a phase shift of the transmitted light is formed with an optically translucent film made of metal, silicon, nitrogen and oxygen. An etch stop layer is added to improve the etch selectivity of the phase shifting layer. A wide range of optical transmission (0.001 % up to 15 % at 157 nm) is obtained by this process.
Abstract:
An attenuating embedded phase shift photomask blank that produce s a phase shift of the transmitted light is formed with an optically translucent film made of metal, silicon, nitrogen or metal, silicon, nitrogen and oxygen. A wide range of optical transmission (0.001 % up to 20 % at 193 nm) is obtained by this process. A post deposition process is implemented to obtain the desired properties (stability of optical properties with respect to laser irradiation and acid treatment) for use in industry. A special fabrication process for the sputter target is implemented to lower the defects of the film.
Abstract:
A method for fabricating a transistor having self-aligned borderless electrical contacts is disclosed. A gate stack (102, 103) is formed on a silicon region (104). An off-set spacer (112, 114) is formed surrounding the gate stack. A sacrificial layer (222) that includes a carbon-based film is deposited overlying the silicon region, the gate stack, and the off-set spacer. A pattern (326) is defined in the sacrificial layer to define a contact area for the electrical contact. The pattern exposes at least a portion of the gate stack and source/drain. A dielectric layer (530) is deposited overlying the sacrificial layer that has been patterned and the portion of the gate stack that has been exposed. The sacrificial layer that has been patterned is selectively removed to define the contact area at the height that has been defined. The contact area for the height that has been defined is metalized to form the electrical contact.
