摘要:
A method of depositing a non-conductive barrier layer onto a metal surface wherein the resistance of the metal remains substantially unchanged before and after the non-conductive barrier layer deposition. The deposition process provides a low temperature processing environment so as to inhibit the formation of impurities such as silicide in the metal, wherein the silicide can adversely increase the resistance of the underlying metal.

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.

An image sensor has an array of pixels of different colors. The pixels may be arranged in a repeating pattern of eight pixels having four rows and two columns. During charge summing operations, the first and third rows may share a floating diffusion and the second and fourth rows may share a floating diffusion. When charge summing is inactive, transfer gates in the first and second columns may be controlled independently, while transfer gates in pairs of rows may be controlled simultaneously. When charge summing is active, summed charges from pixels of the same color in the first and third rows may be placed on the floating diffusion shared by the first and third rows and summed charges from pixels of the same color in the second and fourth rows may be placed on the floating diffusion shared by the second and fourth rows.

In one aspect, the invention includes a semiconductor processing method. An antireflective material layer is formed over a substrate. At least a portion of the antireflective material layer is annealed at a temperature of greater than about 400° C. A layer of photoresist is formed over the annealed antireflective material layer. The layer of photoresist is patterned. A portion of the antireflective material layer unmasked by the patterned layer of photoresist is removed. In another aspect, the invention includes the following semiconductor processing. An antireflective material layer is formed over a substrate. The antireflective material layer is annealed at a temperature of greater than about 400° C. A layer of photoresist is formed over the annealed antireflective material layer. Portions of the layer of photoresist are exposed to radiation waves. Some of the radiation waves are absorbed by the antireflective material during the exposing.

Differently-sized features of an integrated circuit are formed by etching a substrate using a mask which is formed by combining two separately formed patterns. Pitch multiplication is used to form the relatively small features of the first pattern and conventional photolithography used to form the relatively large features of the second pattern. Pitch multiplication is accomplished by patterning a photoresist and then etching that pattern into an amorphous carbon layer. Sidewall spacers are then formed on the sidewalls of the amorphous carbon. The amorphous carbon is removed, leaving behind the sidewall spacers, which define the first mask pattern. A bottom anti-reflective coating (BARC) is then deposited around the spacers to form a planar surface and a photoresist layer is formed over the BARC. The photoresist is next patterned by conventional photolithography to form the second pattern, which is then is transferred to the BARC. The combined pattern made out by the first pattern and the second pattern is transferred to an underlying amorphous silicon layer and the pattern is subjected to a carbon strip to remove BARC and photoresist material. The combined pattern is then transferred to the silicon oxide layer and then to an amorphous carbon mask layer. The combined mask pattern, having features of difference sizes, is then etched into the underlying substrate through the amorphous carbon hard mask layer.
