This invention relates to a subsurface breakdown zener diode having an internally protected P-N junction and a method of fabrication thereof. A semiconductor substrate (10) of one conductivity type (P) has a deposit of semiconductor material (P + ) of the same conductivity type but more heavily doped over which an epitaxial layer (14') of semiconductor material of another semiconductor conductivity type (N) is grown and whereby the deposit becomes a buried layer (12'). Semiconductor material of the one conductivity type and intermediate doping is diffused into an annular region (18) in the epitaxial layer while at the same time a quantity of the same material is diffused into a region (20') centrally of and spaced from the annular region (18'). Both diffusions are carried out to contact with the buried layer (12'). Material (28') of the other conductivity type and doped more heavily than the epitaxial layer (14') is diffused over the centrally diffused material and carried out to convert the first diffusion to the opposite conductivity type for a substantial depth into the epitaxial layer (14') whereby a pn + junction is formed completely beneath the surface. Contacts for the zener diode are made to the annular diffusion region (18') and the diffusion region (28').

The invention relates to a method of etching surfaces such as silicon dioxide, silicon nitride and silicon carbide by exposing the surface simultaneously to a noble gas halide such as fluorinated xenon compound and radiation such as electron beam radiation. The etch rate of silicon dioxide achieved by the present invention, as illustrated in Figure 1, is about 200 angstroms per minute.

A bubble storage system includes a closed loop propagation pattern suitable for use with a bubble lattice. The closed loop propagation pattern (12A-H) is folded and contains, for example, segments of a hexagonal lattice (18A-D, 20A-D, 22A-D, 24A-D) connected by 60° turns to obtain a close pack bubble storage configuration. The bubbles are propagated along the pattern consisting, preferably, of C-bar or chevron type permalloy elements by a rotating magnetic field in the plane of the pattern. In a preferred embodiment, the folded closed loop propagation pattern is surrounded by a region of non-propagating bubbles retained by permalloy dot confinement means (26).
