摘要:
A high performance PN silicon semiconductor device having an arsenic or antimony doped N region which gives a substantial improvement over similar phosphorous doped regions. Arsenic atoms in the N type emitter region of an NPN device tends to squeeze the P-type impurity, such as boron in the base into a narrow-base layer. For the same integrated base doping, a much narrower base can be obtained with arsenic-doped emitters than with phosphorous-doped emitters.

A PROCESS IF DISCLOSED FOR MANUFACTURING MERCURYDOPED GERMANIUM PHOTOCONDUCTOR MATEIAL HAVING A SHORT TIME CONSTANT AT LIQUID NEON TEMPERATURES. THE PROCESS INCLUDES REFINING THE GERMANIUM BY A NUMBER OF MOLTEN ZONE-REFINING PASSES TO REDUCE TH IMPURITIES WHICH ACT AS SHALLOW ACCEPTORS TO A LEVEL ON THE ORDER OF 10**12 ATOMS/CM.3 OR LESS AND THEN COMPENSATING THE REMAINING SHALLOW ACCEPTORS WITH SHALLOW DONORS SUCH AS ANTIMONY OR ARSENIC AND THEN DOPING THE GERMANIUM WITH MERCURY FROM THE VAPOR STATE TO A LEVEL ON THE ORDER OF 10**14 ATOMS/CM.3 OR GREATER.
摘要:
A semiconductor element with a semiconductor body with pnjunction at the surface. At least the pn-junction is provided with an insulating layer. The insulating coating contains bivalent lead ions, and an additive whereby an oxide coat at the surface of the semiconductor body becomes permeable to bivalent lead ions. The additive contains fluorine ions or phosphate ions.
