Title: Mfg. self-aligned gallium arsenide MESFET - involves forming T=shaped tungsten gate electrode
Inventor: PARK HYUNG MOO
IPC: H01L29/417
Filed: 1989-11-30
Abstract: Mfr. of a self-aligned MESFET with a T-shaped tungsten gate electrode involves (a) applying a thin Si layer over the entire surface of a semi-insulating GaAs substrate by plasma-enhanced CVD, applying a Si3N4 layer by photo-CVD and ion implanting to produce an n-active layer using a photo-mask; (b) forming a gate electrode pattern by etching the Si3N4 layer using. the photo-mask; (c) selectively depositing tungsten by CVD only on the exposed Si layer and not on the Si3N4 layer; (d) thickening the tungsten in the transverse direction to form a T-shape; (e) forming an n+-layer by ion implantation using the T-shaped tungsten gate such that the gap between the gate electrode and the n+-layer is 1000-2000 Angstroms; (f) activating the n- and n+-layers using the Si layer and the Si3N4 layer as cover film; (g) ion implanting through the Si and Si3N4 layers to provide insulation between the devices; and (h) etching the Si and Si3N4 layers and applying an ohmic metallisation (AuGe/Ni) by a lift-off technique using a photo-mask to form a source and a drain. ADVANTAGE - The process minimises impurity problems caused by exposure of the GaAs layer to air and minimises mechanical damage during gate electrode application.  Additionally, it avoids As evapn. during the high temp. activation process.  The process is simple compared with the conventional SAINT process (self-aligned implantation of n+-layer technology).

Title: Edge modification of semiconductor wafers before epitaxial deposition - by grinding edges with profiled tool to form rounded edge with tapering planes merging with surfaces, an epi-crown being deposited
Inventor: HARBARGER JOSEPHINE
IPC: H01L21/205
Filed: 1990-10-23
Abstract: The semiconductor wafer is processed, before epitaxial depsn, by removing the sharp corners and forming a profile on the edge in a single operation. The profile is a tapering plane (50) from the top surface to the edge and from the bottom surface (54) to the edge. The length of the taper from the top surface (52) is less than that from the bottom surface (56). The angle between the tapering plane and the surface into which it leads is pref 15-30 degrees. Also claimed is the use of curved planes for the taper. The wafer is then submitted to epitaxial deposition on the top surface of the wafer (88,89), resulting in a deposition also on the edge (90) and tapered part of the underside (92). The profile is formed by grinding of the wafer's edge by a profiled grinding tool in which the shape of the tapering planes has been formed, including a curved surface (58) for the part of the edge between the tapers. In the tool the outer edge (82) at the top of the tool is set  back compared with that of the lower part of the groove. USE/ADVANTAGE - The process requires a single step to complete the rounding of the edge and formation of both tapering planes. The use of two different lengths allows elimination of the epi-crown during subsequent deposition. This improves the yield of devices made on those wafers. The process is used for the prepn of semiconductor wafers for epitaxial depsn.

Patent DE-4042307-A1 (DE)
Inventor: TAVANA MOHAMMAD-SADEGH
IPC: A61F6/04
Filed: 1990-12-31
Abstract: The invention relates to diametrically polarised condoms (polardoms) composed essentially of two unseparated, i.e. one-piece or breaklessly merging, approximate halves. As their rear approximate half has a smaller diameter and their front approximate half has about the same diameter as the penis itself, the front approximate half of the polardom remains axially still in the vaginal passage during the axial movement of the penis, whereby, with the aid of an additional lubricant, the penis is subjected within it to a slight axial natural movement which thus provides friction in relation to the inner surface of the polardom and hence finally the frictional sensation which is lost in the use of an ordinary condom is restored.
