  • Patent number: 7981482
    Abstract: Methods for forming doped silane and/or semiconductor thin films, doped liquid phase silane compositions useful in such methods, and doped semiconductor thin films and structures. The composition is generally liquid at ambient temperatures and includes a Group IVA atom source and a dopant source. By irradiating a doped liquid silane during at least part of its deposition, a thin, substantially uniform doped oligomerized/polymerized silane film may be formed on a substrate. Such irradiation is believed to convert the doped silane film into a relatively high-molecular weight species with relatively high viscosity and relatively low volatility, typically by cross-linking, isomerization, oligomerization and/or polymerization. A film formed by the irradiation of doped liquid silanes can later be converted (generally by heating and annealing/recrystallization) into a doped, hydrogenated, amorphous silicon film or a doped, at least partially polycrystalline silicon film suitable for electronic devices.

  • Patent number: 7977143
    Abstract: A CMOS image sensor and fabricating method thereof are disclosed. The method includes forming a plurality of photodiode regions on a semiconductor substrate, forming a plurality of color filters respectively corresponding to the photodiode regions, forming a planarization layer on the color filters, forming a protective layer on the planarization layer, and forming a microlens layer comprising a plurality of microlenses corresponding to the photodiode regions by depositing a low-temperature oxide layer on the protective layer and then patterning the low-temperature oxide layer. After the planarization layer is formed, the protective layer is formed by plasma processing. Thus, the planarization layer can be protected from chemical penetration via numerous pin holes in the microlens layer in the course of wet processing. Accordingly, the method prevents the microlens from lifting from the planarization layer.

  • Patent number: 7973347
    Abstract: Disclosed is a method of fabricating a CMOS (Complementary Metal Oxide Silicon) image sensor. The method includes the steps of: forming a device protective layer and a metal interconnection on a substrate formed with a light receiving device; forming an inner micro-lens on the metal interconnection; coating an interlayer dielectric layer on the inner micro-lens and then forming a color filter; and forming an outer micro-lens including a planarization layer and photoresist on the color filter. The inner micro-lens is formed by depositing the outer layer on dome-shaped photoresist. The curvature radius of the inner micro-lens is precisely and uniformly maintained and the inner micro-lens is easily formed while improving the light efficiency. Since the fabrication process for the CMOS image sensor is simplified, the product yield is improved and the manufacturing cost is reduced.
