Filed: 2001-12-31
Abstract: PURPOSE: A method for forming a capacitor of a semiconductor device is provided to be capable of easily forming a high permittivity material layer and securing capacitance enough by using an ALD(Atomic Layer Deposition). CONSTITUTION: The first and second sources are adsorbed on the surface of a semiconductor substrate in a reaction chamber. The first purge process is carried out in the reaction chamber. An Atomic layer made of SrO or Ar/O2 is formed by reacting between the adsorbed first and second sources using plasma type Ar/O2 mixed gas flowed into the reaction chamber. The second purge process is carried out for removing by-product and remaining Ar/O2 gas. Then, the second source or the first source is adsorbed on the surface of the semiconductor substrate. After carrying out the third purge process, an oxidizing reaction is induced by supplying the plasma type Ar/O2 mixed gas. The fourth purge process is carried out by using Ar/O2 mixed gas for removing remaining gas and by-product. A high permittivity material layer having a predetermined thickness is formed by repeatedly carrying out the processes.

The signal from the base station(BTSA) is encoded using the first rate convolutional encoder while the signal transmitted from the base station(BTSB) is encoded using the second rate convolutional encoder. Since the multiple base station links result in a different number of symbols being received for each bit transmitted, the symbols received for each link cannot be simply combined. Therefore, the resulting symbols are passed to multiple branch metric circuits(210,211), where branch metrics for the symbols are obtained. After the ith branch metrics for the base stations(BTSA,BTSB) are computed, the branch metrics for each base station are passed to a combiner(212) where they are combined.
