IPC: H04B1/40
Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To suppress a noise level without losing a voice quality of a speech voice independently of quantity of ambient noise in the portable telephone system. SOLUTION: A transmission signal received from a transmission microphone 1 in the portable telephone system is given to a transmission signal level detection circuit 14 consisting of a BPF and a level detection section, where the signal is divided into pluralities of frequency bands and respective transmission signal levels are detected. A surrounding noise signal received from a noise microphone 9 is given to a noise level detection circuit 11 consisting of a BPF and a level detection section, where the noise signal is divided into pluralities of frequency bands and respective noise signal levels are detected.  A control section 13 calculates a correction to suppress the transmission signal at each frequency band depending on the transmission signal levels and the noise levels and allows a frequency characteristic correction circuit 12 to change the frequency characteristic of the transmission signal. Since only the frequency bands at which the surrounding noise levels are high are suppressed, the noise level is suppressed without much losing the voice quality of the speech.

Title: Sequencing of recipe step for hdd-vdd treatment of optimum k
Inventor: ORCZYK MACIEK
IPC: H01L21/31
Filed: 1998-06-03
Abstract: PROBLEM TO BE SOLVED: To produce a stabilized halogen-doped silicon oxide film having a low dielectric constant and low sensitivity for wafer resistance by a method, wherein a silicon oxide layer, containing first and second halogens, is formed on a non-doped silicon glass layer. SOLUTION: When fluorine is initially introduced into a chamber 13, the surface temperature of a wafer is secured still hot, at least 100 deg.C. After the flow-in of the fluorine has started, the power of plasma is lowered, the wafer is cooled and the net volumetric rate of layer is increased by increasing the net deposition versus etching ratio. Then, the density of fluorine in the chamber 13, i.e., the taking-in of fluorine into the layer is increased. As a result, a layer, having a small quantity of free fluorines and a low dielectric constant, can be obtained in the sequence described above. The decrease of free fluorines enhances stability and the cloudiness generated after the formation of the layer and the formation of bubbles are decreased.
