Title: Formation of diffused layers of controllable profile of dopants - using doped glass diffusion sources and selecting of gas-ambient to influence diffusion rate of impurities through glass
Inventor: TSUNASHIMA YOSHITAKA
IPC: H01L21/8242
Filed: 1990-04-30
Abstract: A diffusion process is used to construct a semiconductor device by first depositing a silicon-oxide layer containing dopant as a diffusion source on the semiconductor surface. The diffusion process featuers a step to oxidise dopants in the oxide layer and/or a step to reduce dopants in the oxide layer by altering the diffusion ambient. Reduction is pref. a heat-treatment which uses an ambient containing H2, pref. 2-60%, especially 5-20%. The process claimed consists of a reduction step to reduce the diffusion velocity of part of the dopant contained in the glass, a first diffusion step to diffuse dopant into the substrate, an oxidation step to increase the diffusion rate of part of the dopant and then a second diffusion step. The glass-layer formed may contain several types of dopant or a single dopant. Therefore the process can also reduce and increase the diffusion rate of one of the dopants contained. Pref. combinations of dopants are As and B as well as Sb and P. In both cases it is the first dopant element which is affected by the reduction/oxidation treatments. The first diffusion step may also be combined with the reduction especially by heating up the substrates in a reducing ambient. Also claimed is the depsn. of successive glass-layers with different compsns., of which the first layer contains at least the first type of dopant (As or Sb) and the second layer contains at least the second type of dopant (B RESP..P).

Patent DE-4101562-A1 (DE)
Inventor: INGELHEIM PETER
IPC: F16H21/44
Filed: 1991-01-21
Abstract: The invention concerns an adjustable control gear for changing the transmission ratio in mechanical linear, pivoting and planetary transmission systems, in particular for applications in pneumatic control units and vehicule steering systems. The transmission systems operate without toothed wheels or racks. The control gear  (6...8) rotates about a spindle (9) fixed to the housing, thus changing continuously the transmission ratio in linear and pivoting transmission systems. In planetary transmission systems, a ratio-changing arrangement of this kind gives a transmission with two ratios 1:1 and 1:2. Connecting such two-stage planetary transmisson systems in series and in parallel enables multi-stage transmissions with very finely stepped transmission ratios to be designed.
