摘要:
Disclosed is a method for depositing a tungsten silicide layer on a wafer coated with a polysilicon layer in a CVD process chamber. A surface of the polysilicon layer is pre-treated by introducing a hydrogen compound gas including any elements among group III elements or group V elements of the periodic table into the CVD process chamber. The tungsten silicide layer is deposited on the polysilicon layer by introducing a silane source gas and a tungsten source gas into the CVD process chamber. Since the surface of the polysilicon layer is pre-treated using the hydrogen compound gas before the tungsten silicide layer is deposited on the polysilicon layer, void generation is prevented on an interfacial surface between the tungsten silicide layer and the polysilicon layer.

摘要:
Disclosed are a method for adjusting the account balance of an advertiser in keyword advertising, the method comprising the steps of: maintaining an advertiser information database for storing bidding price information, minimum balance for account maintenance, and information on the account balance by each search result; generating a search result list including at least one search result associated with a predetermined keyword on the basis of the bidding price information, thereby maintaining the generated search result list in a search result database; receiving a selection of a search result from a user, with respect to the search result list provided in response to a predetermined search request including the keyword; searching for minimum balance for account maintenance and information on the account balance associated with the search result by referring to the advertiser information database, in case that the search result list is generated; increasing the number of clicks about the selected search result, only in case that the account balance searched in association with the search result is more than the minimum balance for account maintenance; computing advertising cost of a predetermined first period by using bidding price information associated with the number of accumulated clicks and the search result, after the predetermined first period elapses; subtracting the computed advertising cost from the account balance associated with the search result; and updating the advertiser information database by using information on the subtracted account balance, and a system thereof.
