  • Patent number: 7851125
    Abstract: Provided are a mask pattern including a silicon-containing self-assembled molecular layer, a method of forming the same, and a method of fabricating a semiconductor device. The mask pattern includes a resist pattern formed on a semiconductor substrate and the self-assembled molecular layer formed on the resist pattern. The self-assembled molecular layer has a silica network formed by a sol-gel reaction. To form the mask pattern, first, the resist pattern is formed with openings on an underlayer covering the substrate to expose the underlayer to a first width. Then, the self-assembled molecular layer is selectively formed only on a surface of the resist pattern to expose the underlayer to a second width smaller than the first width. The underlayer is etched by using the resist pattern and the self-assembled molecular layer as an etching mask to obtain a fine pattern.

  • Patent number: 7827519
    Abstract: Disclosed is an improved method, system, and computer program product for preparing multiple levels of semiconductor substrates for three-dimensional IC integration. Some embodiments utilize the process and design models to check and fabricate the insulating dielectric layer (IDL) separating the first and the second film stacks on separate substrates and then prepare the surface of the IDL to receive an additional layer of semiconductor substrate for further fabrication of the chips. Yet some other embodiments further employ the design and process models to ensure the IDL and the semiconductor substrate are sufficiently flat, or are otherwise satisfactory, so the three-dimensional integrated circuits meet the reliability, manufacturability, yield, or performance requirements. Yet some other embodiments further employ design and process models to place the vias connecting the multiple film stacks.

  • Patent number: 7704673
    Abstract: A photo acid generator (PAG) or an acid is used to reduce resist scumming and footing. Diffusion of acid from photoresist into neighbors causes a decreased acid level, and thus causes resist scumming. An increased acid layer beneath the resist prevents acid diffusion. In one embodiment, the increased acid layer is a layer of spun-on acid or PAG dissolved in aqueous solution. In another embodiment, the increased acid layer is a hard mask material with a PAG or an acid mixed into the material. The high acid content inhibits the diffusion of acid from the photoresist into neighboring layers, and thus substantially reduces photoresist scumming and footing.

  • Patent number: 7639864
    Abstract: Optimization of illumination for a full-chip layer is disclosed. A pitch frequency of the full-chip layer is determined so as to generate a pitch frequency histogram of the full-chip layer. The pitch frequency indicates how often a given pitch occurs in the full-chip layer. The pitch frequency histogram is equated to be the first eigenfunction from the sum of coherent system representation of a transformation cross coefficient. An integral equation for the first eigenfunction of the transformation cross coefficient is solved so as to define the optimal illumination for imaging the full-chip layer.
