    • PURPOSE: A method for manufacturing semiconductor devices is provided to improve a filling degree of a tungsten layer as well as productivity of semiconductor devices. CONSTITUTION: A method for manufacturing semiconductor devices comprises the following steps of: forming a hole on an insulating layer, which is arranged on the surface of a semiconductor substrate(S10); heating the semiconductor substrate in a reaction chamber at 330-400°C(S20); injecting one gas selected from tungsten-containing gas, B2H6 gas, and SiH4 gas into the reaction chamber; forming a first tungsten layer in the hole(S30); injecting H2 gas or inert gas into the reaction chamber; raising the temperature of the semiconductor substrate up to 370-410°C for 30 seconds(S40); and forming a second tungsten layer on the first tungsten layer(S50).
    • 目的:提供半导体器件的制造方法,以提高钨层的填充度以及半导体器件的生产率。 构成:制造半导体器件的方法包括以下步骤:在布置在半导体衬底的表面上的绝缘层上形成孔(S10); 在330-400℃下在反应室中加热半导体衬底(S20); 将从含钨气体,B 2 H 6气体和SiH 4气体中选出的一种气体注入到反应室中; 在孔中形成第一钨层(S30); 将H 2气体或惰性气体注入反应室; 将半导体衬底的温度升高到370-410℃30秒(S40); 以及在所述第一钨层上形成第二钨层(S50)。
