Abstract: A mask, including a first clamping region and a second clamping region opposite to each other in a first direction, and at least one mask opening region disposed between the first clamping region and the second clamping region. The mask opening region is in a first initial shape before being tensioned. The mask opening region is in a first target shape during an evaporation deposition process. The first initial shape is different from the first target shape. The first initial shape includes a compensation pattern with respect to the first target shape. The compensation pattern includes a tensile deformation pattern and a thermal deformation pattern.

Abstract: The present disclosure relates to a fosphenytoin sodium solid composition, a lyophilization method of fosphenytoin sodium, and use of the fosphenytoin sodium solid composition. The fosphenytoin sodium solid composition comprises fosphenytoin sodium and at least one carbohydrate.
