Title: Method for manufacturing semiconductor memory devices
Inventor: KUNITO MASAO
IPC: H01L21/8246
Filed: 1997-08-28
Granted: 1999-06-01
Abstract: In a conventional method, formation of an intermediate layer to serve as an insulating layer between a metal terminal on the surface of the device and a gate electrode of the device, along with heat treatment of the intermediate layer, is executed after formation of implanted diffusion layers to serve as bit lines of the device. In the method for manufacturing semiconductor memory devices according to the present invention, formation of the intermediate layer and heat treatment thereof are executed before formation of the implanted diffusion layers. The formation of the implanted diffusion layers is executed by introducing an impurity material into a memory cell region of the device with energy enough to penetrate the intermediate layer. According to the method, heat diffusion of the impurity material due to the heat treatment step is prevented, and thus 'Lmin', ie. The minimum channel length can be set shorter and higher degree of integration of devices is made possible. Moreover, the impurity material is also introduced in a calipers region of the device. Part of the intermediate layer on the calipers region is removed and the impurity material in the calipers region is oxidised so as to form a calipers pattern. By the calipers pattern, positioning of the photoresist layer used in the data writing process can be executed with high precision, and thus manufacturing process yields of devices can be raised.

Granted: 2000-01-21
Abstract: A speech encoding method and apparatus and an audio signal encoding method and apparatus in which the processing volume in calculating a weight value for perceptually weighted vector quantization may be decreased to speed up the processing or to relieve the load on hardware. To this end, an inverted LPC filter finds LPC (linear prediction coding) residuals of an input speech signal which are processed with sinusoidal analysis encoding by a sinusoidal analysis encoding unit. The resulting parameters are processed by a vector quantizer with perceptually weighted vector quantization. For this perceptually weighted vector quantization, the weight value is calculated based on results of orthogonal transform of parameters derived from the impulse response of the transfer function of the weight.
