Title: Shadow projecting mask for ion implantation and lithography by ion beam radiation
Inventor: BOHLEN HARALD
IPC: G03F1/20
Filed: 1981-10-30
Granted: 1988-03-10
Abstract: The mask is made using a silicon wafer(b), which is coated with a thin, p+ doped Si Layer(a). Wafer(b) contains troughs so it forms a grid of ribs below layer(a), which contains through holes(c) extending into the troughs. The bores of holes(c) and the surface of layer(a) are covered with an electrically-and thermally- conducting material(I), which resists attack by the ions, and has a thickness which prevents the ions from entering the silicon(a,b). Material (I) does not cause any deformation of the mask due to temp. changes or internal stress. Material (I) absorbs ions, and is esp. tungsten or tantalum; but a combination of materials which absorb or resist ions may be used. A diffusion barrier of Si3N4 may be located between material (I) and layer(a). Extremely small semiconductor devices can be made using masks which are dimensionally stable and which do not contaminate semiconductors being treated by ions.

Title: Balloon envelope
Inventor: BARNES TRACY LAY
IPC: B64B1/40
Filed: 1982-04-26
Granted: 1986-08-21
Abstract: A balloon envelope is disclosed which has the ability to minimize and isolate destructive tears, and which comprises a latticework of interconnected vertical and lateral reinforcing tapes which form open areas therebetween, and with a fabric panel overlying and covering each open area. The fabric panels are sewn to the surrounding tapes in a manner such that there is no direct interconnection between adjacent fabric panels. The envelope is fabricated by a procedure wherein the vertical gores, which are each composed of a vertical array of the fabric panels, are initially formed by sewing adjacent side edges of adjacent panels to intermediate laterally directed tapes, and then sewing a vertical tape component along each side of the resulting array of panels. The vertical side edges of the thus formed gores are then sewn together to form a sphere-like configuration.
