Title: Growing method of crystal
Inventor: SAKAI KAZUO
IPC: H01L21/208
Filed: 1978-08-08
Abstract: PURPOSE:To reduce the change in the composition of crystal, by setting a temperature fall speed of 0.18 deg.C/min or less and a growth start supercooling temperature of 5 deg.C or more when epitaxially growing Im1-XGaXAs(0.44<X<0.50) at liquid phase by a slow cooling method. CONSTITUTION:A graphite-made slide boat is used to grow an InGaAs layer of In0.53Ga0.47As or the like on the (100) face of an InP substrate. After a solution containing weighed quantities of In, GaAs and InAs is heated to 640 deg.C, the solution is slowly cooled at a temperature fall speed of 0.18 deg.C/min. When the solution reaches 628 deg.C, it is brought into contact into the InP substrate. The supercooling temperature at the beginning of the growth is set at 5 deg.C or more. As a result, flat crystal is deposited on the surface of the InP substrate. Since the supercooling temperature is as high as 5 deg.C or more, the velocity of the growth can be made as high as 1mum/min.

Title: Method of positioning for electron beam transcription
Inventor: TABATA MITSUO
IPC: H01L21/027
Filed: 1983-05-31
Abstract: PURPOSE:To enable to largely shorten the time required for positioning by a method wherein each mark pattern of a photoelectric mask and a wafer is so formed that the area of superposition thereof varies with the amount of positional slippage in a quadratic functional manner. CONSTITUTION:An electron beam is generated by means of said mask 3, and the beam is converged on the wafer 5. The electron beam for positioning generated from the first mark on the mask is converged on the second positioning mark on the wafer 5. Here, an AC deflection field is given by letting a current containing AC components flow to a deflection coil 13, thus modulating the beam. At this time, when rectangular wave is selected as the modulation waveform, and the amplitude is integral multiples of the pitch of micro positioning patterns, the output characteristic after synchronous detection becomes only the component from coarse positioning patterns. Besides, a linear region becomes wider in accordance with the positional slippage, if the positioning pattern for the mask 3 and the wafer 5 is kept formed in such a manner that the output characteristic of X-rays from the coarse positioning pattern becomes expressed in terms of a guadratic functional curve. Therefore, the detection of positional slippage over a wide range is enabled.
