    摘要: A methods of forming a microlens structure are provided. An embodiment of the method comprises exposing a photoresist layer a predetermined focus and exposure to sensitize a lens-shaped region within the photoresist layer. The photoresist layer is then developed to form a lens-shaped region within the photoresist layer. The lens-shaped region may then be transferred to an underlying material. The underlying material may be a transparent material within which a lens is subsequently formed. Alternatively, the underlying material is a lens material that will form the microlens once the lens-shaped region is transferred.

The oxide layer is formed at a temperature of less than 400° C. using an inductively coupled plasma source. In some aspects of the method, the oxide layer is more than 20 nanometers (nm) thick and has a refractive index between 1.45 and 1.47. In some aspects of the method, the oxide layer is formed by plasma oxidizing the silicon layer, producing plasma oxide at a rate of up to approximately 4.4 nm per minute (after one minute). In some aspects of the method, a high-density plasma enhanced chemical vapor deposition (HD-PECVD) process is used to form the oxide layer. In some aspects of the method, the silicon and oxide layers are incorporated into a thin film transistor.

    摘要: A method of improving the electrical properties of high dielectric constant films by depositing an initial film and implanting oxygen ions to modify the film by decreasing the oxygen deficiency of the film while reducing or eliminating formation of an interfacial silicon dioxide layer. An initial high dielectric constant material is deposited over a silicon substrate by means of CVD, reactive sputtering or evaporation. Oxygen ions are preferably implanted using plasma ion immersion (PIII), although other methods are also provided. Following implantation the substrate is annealed to condition the high dielectric constant film.

    摘要: A high-k dielectric film is provided which remains amorphous at relatively high annealing temperatures. The high-k dielectric film is a metal oxide of either Zr or Hf, doped with a trivalent metal, such as Al. Because the film resists the formation of a crystalline structure, interfaces to adjacent films have fewer irregularities. When used as a gate dielectric, the film can be made thin to support smaller transistor geometries, while the surface of the channel region can be made smooth to support high electron mobility. Also provided are CVD, sputtering, and evaporation deposition methods for the above-mentioned, trivalent metal doped high dielectric films.
