    摘要: A method for forming shallow trench isolation is disclosed. A pad oxide layer and a mask layer are sequentially formed on a substrate. Afterwards, an opening is formed through the mask layer and the pad oxide layer such that regions of the substrate are exposed. Thereafter, the exposed regions are etched to form trenches inside said substrate. Next, nitrogen ions are implanted into the sidewall of the trenches to form a silicon nitride layer, and then a siliconoxynitride layer is formed inside the sidewall of the trenches. Subsequently, a silicon oxide layer is formed on the siliconoxynitride layer and on the mask layer. The excess portion of the silicon oxide layer over said mask layer is removed to expose the mask layer, and then the mask layer is removed away. Finally, the pad oxide layer is removed by using hydrofluoric acid (HF).

    摘要: A method for determining near-surface doping concentration is provided by utilizing surface photovoltage. A monochromatic light pulse is applied to a semiconductor substrate. When the energy of the incident light is larger than the energy gap of the semiconductor substrate, the light is absorbed by the substrate and thereby generates enough charge carriers. The carriers diffuse to the surface of the substrate and result in lowering the surface barrier, and hence, cause a shift of the surface voltage. The difference of the surface voltages, before and after the light pulse applied, is measured by using a surface photovoltage probe. Then, the doping concentration near the surface of the substrate can be determined according to the difference of the surface voltage.

    摘要: The present invention provides a method of forming different thickness” of a gate oxide layer simultaneously, by employing a pulse Nitrogen plasma implantation. The method provides a semiconductor substrate with the surface of the silicon in the semiconductor substrate separated into a first region and a second region at least. Then a thin surface on the surface of the silicon of the first region is implanted using a first predetermined concentration of the Nitrogen ions. The thin surface on the surface of the silicon in the second region is implanted using a second predetermined concentration of the Nitrogen ions. An oxidation process is subsequently performed. The first predetermined thickness and the second predetermined thickness of the silicon oxide layer are formed simultaneously on the surface of the silicon in the first region and in the second region. The Nitrogen ions are implanted in the surface of the silicon by forming the pulse nitrogen plasma in-situ. The first predetermined concentration is not equal to the second predetermined concentration.

    摘要: A method for suppressing boron penetrating the gate dielectric layer by pulsed nitrogen plasma doping. A pulsed nitrogen plasma doping process is utilized to dope nitrogen ions into the surface layer in the channel region of the semiconductor substrate. A thermal oxidation step is then performed to form a gate dielectric layer commixed with oxide and oxynitride over the channel region of the semiconductor substrate to avoid boron penetration effect accruing while a boron doped polysilicon layer is subsequently formed on the gate dielectric layer.

    摘要: This invention relates to a method for forming a shallow junction, more particularly, to the method for forming a ultra-shallow junction by using a arsenic plasma doping fashion. The present invention uses the arsenic plasma doping fashion to dope arsenic ions to the junction of the semiconductor and then passes through a post anneal process. The resistance value of the junction can be controlled. The present invention also uses the depth of doped arsenic ions to control the depth of the junction and to restrain the diffusion of the arsenic ions. Then the region of the junction can be reduced successfully to become a ultra-shallow junction. This ultra-shallow junction is a low resistance value and excellent electricity junction.

    摘要: A duplex light transceiver module comprises a body having a light receiving module, a light transmitting module, and an optical fiber adaptor. The light emitting module has a laser diode chip and a metal header bearing the laser diode chip. A metal cap of the duplex transceiver module is combined with a round cylindrical focusing element which is installed ahead a light emitting end of the laser diode chip. One end of the cylindrical focusing element is formed with a ramp. A wavelength-division medium is evaporation-coated upon the ramp of the wavelength-division medium. The wavelength-division medium has different permeability so that light at one side facing the optical fiber adaptor will reflect light totally and light at one side facing the optical transmitting module will pass through the wavelength-division medium to be received by the light receiving module.

    摘要: A duplex focusing device is installed a duplex light transceiver module for transmitting light signals. The duplex focusing device comprises a ball lens assembly and a body. The ball lens assembly has a first lens and a second lens both being symmetrical half ball matching to each other. A layer of wavelength-division medium is placed between the first and second lens to ensure that light transmitted from a laser diode will transmit through the ball lens assembly. Thereby, the light transmitting into the ball lens assembly will have a part being reflected by the second lens. The body serves for receiving and fixing the ball lens. The body is formed to cause that both orientations of the first lens and the second lens are adjustable with respect to the body.
