Abstract:
A method for upgrading qualities of DRAM capacitors and wafer-to-wafer uniformity is disclosed. In order to effectively prevent wafers from contaminations, the invention uses an additional silane purge process in situ before performing a SHSG seeding process on the wafers. The silane purge process of this invention utilizes the original silane seeding gas inlet. In this manner, not only thicknesses and surface areas of the SHSG seeds and capacitances of DRAMs can be increased, but also wafer-to-wafer uniformity can be upgraded.
Abstract:
A method for forming a capacitor containing selective hemispherical grained (S-HSG) polysilicon is disclosed. In this invention, dopant implantation is incorporated after the S-HSG growth to replace conventional wet clean procedure. The elimination of the cleaning treatments avoids the incidents of residue particles (due to cleaning) and minimizes numerous structure defects. The incorporation of the ion implantation technique would make up the insufficiency of doping requirement by applying in-diffusion alone. The combination of the in-diffusion and the implantation for doping procedure could maintain the device with good capacitance level even though the pre-clean procedure is excluded.
Abstract:
An incremental encoder, which comprises a light source, a code wheel, a first photo-sensitive unit, a second photo-sensitive unit, a first inverse-phase photo-sensitive unit and a comparison circuit, is disclosed. The light source provides a detecting light. The code wheel comprises many diaphanous holes. The detecting light is sieved into a light pulse signal by the diaphanous holes when the code wheel is rotating. The first photo-sensitive unit, the second photo-sensitive unit and the first inverse-phase photo-sensitive unit generates the first electronic signal, the second electronic signal and the first inverse-phase electronic signal respectively based on the light pulse signal. The comparison circuit generates a voltage signal by composing the first electronic signal and the first inverse-phase electronic signal, generates a first digital signal based on the voltage signal and the first electronic signal, and generates a second digital signal based on the voltage signal and the second electronic signal.
Abstract:
An output circuit of a player can detect whether a cable is electrically connected to an output port of the output circuit. The output circuit includes a signal circuit and a decision module for detecting whether a cable is connected by detecting voltage change at the output port. If the decision module determines that a cable is connected, the signal circuit will provide video or audio signals of the player to the output port. If the decision module determines that no cable connected, the signal circuit will provide a predetermined detecting signal with nonzero average power to the output port, such that the decision module can detect whether the output end is connected to a cable again by detecting voltage change of the detecting signal.
Abstract:
A silicon oxide layer is formed on a semiconductor wafer by performing a high temperature oxidation (HTO) process using dichlorosilane (SiH2Cl2) and nitrous oxide (N2O), as reacting gases, having a flow rates with a ratio greater than 2:1, respectively. The reacting moles of dichlorosilane to nitrous oxide are in the proportion of 1:2.
