  • Patent number: 5206181
    Abstract: A method for semiconductor wafer scribing utilizing perforated metal areas in the scribe regions. In one form, a method for fabricating a semiconductor device includes forming a plurality of semiconductor die (12) on a semiconductor wafer (10) such that the die are separated from one another by scribe regions (13). A test structure (14) is formed within one of the scribe regions and includes a perforated probe pad (16). In one embodiment, the probe pad is perforated by a plurality of slots (18). The perforations in the probe pad aid in scribing the semiconductor wafer by preventing metal lift-off which often occurs when cutting metal areas.

  • Patent number: 4088698
    Abstract: A method for preparing thiophenolic compounds is described comprising reacting a phenol and hydrogen sulfide in the presence of a vanadia catalyst. It is preferred to carry out the process of this invention at low pressures, i.e. at pressures lower than 100 psi, atmospheric pressure being very suitable, although the process is operable at subatmospheric pressures. Preferred phenols, catalysts and reaction conditions are also described.
