摘要:
Disclosed is a novel DRAM manufacturing method to reduce difficulties due to the high aspect ratio of contact hole for storage electrode. The method comprises the steps of formation of a contact plug on contact areas of bit line and storage electrode at the same time and then, formation of a bit line that is in contact with the contact plug for bit line and finally, making a storage electrode that is as high as the bit line contact with the contact plug for storage electrode.
摘要:
The invention relates to a process for separating 1.alpha.-hydroxyvitamin D compounds from their corresponding 1.alpha.-hydroxy-5,6-trans isomers in a mixture thereof by treating the mixture with a dienophile and then separating the resulting dienophil-adduct of the 1.alpha.-hydroxy-5,6-trans vitamin D isomer from the unreacted 1.alpha.-hydroxyvitamin D compound.
摘要:
