摘要:
A process for etching the surfaces of semiconductor substrates utilizes a texturing tank which introduces a process fluid through a circulating system. The process fluid is heated to a desired temperature and maintained at a desired concentration prior to entering a processing area where laminar flow is produced to more quickly and uniformly roughen the surface of semiconductor substrates. The texturing tank permits removal of bubbles and eliminates temperature stratification in the processing area.
