Patent GB-2212519-A (GB)
Title: Vacuum evaporation and deposition
Inventor: PARMENTER JOHN JAMES
IPC: C23C14/54
Filed: 1988-11-11
Abstract: Deposition of material onto a substrate as illustrated in Figs 2 and 4 comprises evaporating material from a source (2), and controlling the dosage of material at the substrate by moving a shutter (21) between an open position (44) and a closed position (43), characterised in that there is included a closing step comprising beginning to decelerate said shutter before reaching the closed position, subsequently thereby bringing the shutter substantially to rest at the closed position. 
<??>Preferably the motion of the shutter is substantially harmonic with the acceleration of the shutter being directed towards, and proportional to the distance of the shutter from, the point mid-way (45) between the open and closed positions. Contamination is reduced from prior methods and the invention is especially advantageous in molecular beam epitaxy. Figure 2 shows shutter 21 in a closed position 43. Shaft 22 is attached to a cage 34 which has a guiding slot 35. A pin is located in slot 35 and is also affixed to a radius arm 37 which is capable of rotation about a pivot 38. As arm 37 rotates in the direction of an arrow 39 shutter 21 is moved away from the closed position in the direction of an arrow 40. The motion continues until, as shown in Fig 4, the shutter is disposed in an open position at 44. The shutter may remain open at open position 44 for the appropiate time to expose the substrate and then the direction of rotation of arm 37 is reversed, in the direction of an arrow 42, to the closed postion 43 of Fig 2. In this way by moving arm 37 with a substantially angular velocity about pivot 38 it is ensured that the shutter 21 moves with the substantially harmonic motion referred to above.

Title: Network connection mechanism
Inventor: BRANDER JAMES EDWARD
IPC: G06F8/30
Filed: 1989-01-26
Abstract: The present invention discloses a method of creating structure in a computer system by creating data links, so that information can be passed in either, or both, directions along the links. Changing list conditions determine whether or not links are valid and links are created and destroyed accordingly. The ability to change the structure of the computer system means that it is not necessary to predict or prescribe every possible link. In this way problems having a complexity beyond prescriptive programming measures can be solved. <IMAGE>

Title: Method of fabricating solar cells with anti-reflection coating
Inventor: CHAUDHURI ARUP R
IPC: H01L31/0216
Filed: 1989-02-21
Abstract: A process of manufacturing silicon solar cells is described which is characterized by forming on the front surface of a silicon substrate a polysilazane coating by (a) first subjecting the substrate to an ammonia plasma treatment for a predetermined period of time so as to produce hydrogen implantation and (b) subjecting the substrate to a silane and ammonia plasma treatment to obtain additional hydrogen implantation and formation of a polysilazane coating. The polysilazane coating is etched to form a grid electrode pattern, and subsequently the exposed silicon on the front side of the substrate is coated with an adherent coating of a highly conductive metal so as to form a grid electrode. An aluminum coating is applied to the rear side of the substrate so as to form a back electrode. The aluminum coating is heated so as to alloy with the silicon substrate and thereby form an ohmic contact. The ammonia plasma treatment has the effect of enhancing the conversion efficiency of the solar cell by virtue of diffusion of hydrogen into the substrate. The heat treatment for alloying the aluminum tends to cause the implanted hydrogen to diffuse further into the substrate, thereby beneficially altering the bulk diffusion length characteristics of the substrate so as to decrease recombination of the minority carriers produced in response to the incident light.
