    • It is an object to obtain a semiconductor device free from a necessity of stacking a contact hole and a lower electrode, thus preventing occurrence of an error in stacking and enabling the capacitor to be formed precisely. Amorphous silicon 10b is deposited on a interlayer insulating film 9 including the inside portion of the contact hole 9a, and then a resist 14 is applied to the amorphous silicon 10b. Then, a mask for photolithography which has been used to form the contact hole 9a is used to perform a photolithography process to form the resist 14 to have a required shape. Then, implantation of phosphorus ions is performed such that the resist 14 is used as a mask 14a for preventing implantation of ions. Then, the amorphous silicon 10b is subjected to heat treatment to partially single crystallize the amorphous silicon 10b so that single crystal silicon 10c is grown. The difference in the etching rate between the amorphous silicon 10b and the single crystal silicon 10c is used to selectively remove the amorphous silicon 10b by using dry etching technique so that a storage node 10 is formed.
    • 本发明的目的是获得不需要堆叠接触孔和下电极的半导体器件,从而防止堆叠发生错误,并且能够精确地形成电容器。 非晶硅10b沉积在包括接触孔9a的内部的层间绝缘膜9上,然后将抗蚀剂14施加到非晶硅10b。 然后,使用已经用于形成接触孔9a的用于光刻的掩模来进行光刻工艺以形成具有所需形状的抗蚀剂14。 然后,进行磷离子的注入,使得抗蚀剂14用作防止离子注入的掩模14a。 然后,对非晶硅10b进行热处理,以使非晶硅10b部分单晶结晶,从而生长单晶硅10c。 使用非晶硅10b和单晶硅10c之间的蚀刻速率的差异,通过使用干蚀刻技术来选择性地去除非晶硅10b,从而形成存储节点10。

    • A process for recovering components of a catalyst from a mother liquor of liquid phase oxidation in production of aromatic carboxylic acids by liquid phase oxidation of aromatic hydrocarbons having substituents with a gas containing oxygen in a presence of a catalyst comprising cobalt, manganese and bromine in acetic acid or acetic acid containing water as a solvent, which process comprises adding a compound generating an ion of an alkali metal to the mother liquor of liquid phase oxidation obtained after separating crystals of the aromatic carboxylic acid from a reaction fluid of the liquid phase oxidation, bringing the mother liquor containing the compound into contact with an ion exchange resin so that the components of the catalyst are adsorbed to the ion exchange resin and recovering the components of the catalyst comprising cobalt, manganese and bromine ion by passing an elution liquid through the ion exchange resin. By adding the compound generating an ion of an alkali metal to the mother liquor supplied to an ion exchange resin column, contamination of the recovered components of the catalyst with eluted metal ions such as iron can be suppressed and an increase in the concentration of the eluted metal ions in the mother liquor of the oxidation can be prevented. Therefore, the amount of the recycled mother liquor can be increased and the recovery of the catalyst components can also be increased.
