Patent EP-0445596-A2 (EP)
Inventor: ANDERSON ROGER N
IPC: H01L21/26
Filed: 1991-02-21
Abstract: A thermal reactor (100) for epitaxial deposition on a wafer (99) comprises a double-dome vessel (104) and dual beat sources (164,166) each having inner and outer circular arrays (168,180,172,184) of infrared lamps (170,182,174,186) to assure circumferential heating uniformity. Radial h eating uniformity is provided by independent control of inner and outer beating arrays (168,180,172,184) for both the upper and lower beat sources (164,166). The relative temperatures of wafer (99) and susceptor (114) are controlled by adjusting relative energies provided by the upper and lower heat sources (164,166) so that backside migration can be implemented selectively. Reduced pressure operation is provided for by the convex top and bottom domes (116, 118). Due to the provided control over transmitted energy distribution, a susceptor (114) can have low thermal mass so that elevated temperature can be achieved more quickly and cooling can be facilitated as well. This improves throughput and reduces manufacturing costs per wafer (99). Reagent gas introduction can be axial or radial as desired.

Abstract: 2.1. The invention relates to a DC/DC converter (1) having a controllable switch (13) for producing at least one output voltage (Ua), the switched-on duration (D) of the controllable switch (13) being controllable as a function of the output voltage (Ua). Despite a cost-effective and hence "slow" microprocessor, the DC-DC converter is intended to have sufficiently stable control. 
<??>2.2. To this end, it is proposed that the output voltage (Ua) is sampled more than once in the computing time of the microprocessor (13) which is available to calculate the switched-on duration (D) of the controllable switch (13), and that the switched-on duration (D) of the controllable switch (13) can be preset as discrete values (Df), which are determined by means of an output unit (5,6) of the microprocessor (12) and are formed from the respectively determined switched-on duration (D) by means of a coarse quantisation (5) corresponding to the time resolution of the microprocessor (12) and a fine quantisation (6) associated with each quantisation step of the coarse quantisation (5). 2.3.

Abstract: A receiving apparatus for synchronising a digital data clock in a receiver with a digital data clock in a transmitter and a method therefor is disclosed which utilizes two phase-locked loops so as to improve accuracy and jitter performance. One of the phase-locked loops is locked onto positive edges in a received waveform and the other phase-locked loop is locked onto negative edges. The phase-locked loops independently decode the 1's and 0's in the data allowing the transmit data and clock to be readily recovered. Each of the phase-locked loops uses a decoding method in which mid-bit transitions in the encoded received waveform are detected in more than half of the sampling periods within one bit period which further improves the performance of the apparatus.

Abstract: A safety cut-off system for an installation consisting of machines which are designed for interaction has a machine cut-off level (10) in which a dedicated cut-off circuit is allocated to each machine (12a-12h), a zone cut-off level (20) in which cut-off zones can be cut off which consist of groups of associated machines, and a system cut-off level (30) which is allocated to all the machines (12a-12h) in the installation. The cut-off circuits each have an electrically operable switching element (16a-16h) which is connected via safety circuits (13a-13d) to a main box (24) for central control of the safety cut-off system and, through said box, to a power supply (100). The safety circuits (13a-13d) have operable tripping elements (22a, 22b, 32a) at the zone cut-off level (20) and at the system cut-off level (30), are designed as latching circuits and are passed through by the main box in which they can be selectively linked with one another by means of a switching matrix such that groups of associated machines are cut off when one of the tripping elements is operated. In order to connect an additional machine to the safety cut-off system, it is necessary only to connect the cut-off circuit of this machine to the main box (24) via an additional latching circuit. There is no need for any other change to the wiring of the installation since the additional machine is linked to the safety cut-off system in the switching matrix of the main box (24). <IMAGE>
