Title: Method of manufacturing metal film
Inventor: OKADA JUNJI
IPC: H01L29/786
Filed: 1993-05-28
Abstract: PURPOSE:To obtain a metal film having an excellent etching precision and stable characteristics by a method wherein the metal film is etched with one etching liquid having a higher concentration out of two etching liquids having different concentrations containing hydrofluoric acid and thereafter the metal film is etched with another etching liquid. CONSTITUTION:When etching a metal film 16 for an electrode composed of Ti, it is continuously etched using two etching liquids 1, 2 having different concentrations composed of HF-NH4F-HNO3-H2O. The concentration of etching liquid 1 is much higher than the etching liquid 2, and an oxide film or an oxide nitride film formed mainly on a surface of the metal film 16 for an electrode is removed. Thereafter, etching is performed with the etching liquid 2 having a lower concentration than the etching liquid 1, whereby the metal film 16 itself for an electrode is etched to form source and drain electrodes 7a, 7b. Thus, Ti is uniformly etched without causing side etching.

Filed: 1977-12-09
Abstract: PURPOSE: To enable to measure the characteristic parameter which is excellent even under the condition of noise superposition by such as in-room noise, with high accuracy, by taking consideration into that audio has strong periodic nature and in-room noise has no such nature.  
     CONSTITUTION: The fundamental period is picked up from the input signal waveform, and the self-correlativity at the delay time point almost the same or greater than the time represented in the value of the fundamental period thus picked up is calculated. The input signal from the input terminal 201 is digitally coded with a given period Ts by the AD converter 202 and is fed to the fundamental period pick up circuit 203 and the self-correlativity calculation circuit 204. In the circuit 204, the self-correlativity over the delay time area required according to the information in the fundamental period Tp picked up with the circuit 203 is calculated in the distance of Ts. Next, the output of the circuit 204 is fed to the interpolation circuit 205 and it is interpolated with the interpolation processing for the sample values of self-correlativity (i.e. value of self-correlativity), allowing to obtain the self-correlativity at more time points.
