Title: Manufacture of semiconductor device
Inventor: MITSUMA YASUO
IPC: H01L29/80
Filed: 1986-09-19
Abstract: PURPOSE:To form a shallow and steep carrier concentration profile and obtain a semiconductor device with a high operation speed and a high gm by a method wherein a impurity is introduced into a semiconductor substrate by ion implantation and short time annealing is carried out with a lamp which has a peak of its emitted light wavelength distribution in the region of a wavelength shorter than the wavelength absorbing end of the semiconductor substrate as a light source. CONSTITUTION:After an impurity is introduced into a semiconductor substrate 1 by ion implantation, short time annealing is carried out with a lamp which has a peak of its emitted light wavelength distribution in the region of a wavelength shorter than the wavelength absorbing end of the semiconductor substrate 1 as a light source to activate the impurity and an oxide layer or a reformed layer 4 which has a thickness less than the depth of the peak of the impurity concentration profile is formed on the surface of the semiconductor substrate 1 and then oxide layer or the reformed layer 4 is removed. For instance, Si ions are implanted into the surface of a GaAs substrate 1 to form an impurity introduced layer 2. Then the GaAs substrate 1 whose wavelength absorbing end is 0.9 mum is subjected to short time annealing with an Ar arc lamp whose emitted light distribution has a peak at about 0.8 mum as a light source. At that time, Si is activated and an active layer 3 is formed and, at the same time, an oxide layer or a reformed layer 4 is formed.

IPC: H05K13/00
Filed: 1988-09-05
Abstract: PURPOSE:To easily correct position off-set in the theta direction by detecting the position off-set of electronic parts adsorpted to a nozzle and driving a motor for nozzle selection driving on the basis of the detection results to rotate the nozzle. CONSTITUTION:A multi-head 4 that adsorpts electronic parts P reaches an observation stage B by the intermittent rotation of a rotary head 1, and the position off-set of parts P adsorpted in the lower end of a nozzle 4a in the xytheta direction can be observed by an exterior examination apparatus 5. Next, the head 4 corrects the position off-set in the theta direction by a motor 18 driving to rotate a nozzle 4a about an elevator shaft in the theta correction area F. At this time, since as the nozzle 4a rotates, a center O moves, the position off-set caused newly in the x and y directions are corrected simultaneously. This makes it possible to easily make correction with a small, low-capacity motor.

Abstract: PURPOSE:To definitely record and display the information of the surrounding area of a fishing net by providing a means which makes writing operations by extending the writing period as time elapses from the emission of a searching signal when writing reflect signals in a transmitting side memory and means which reads out the reflect signals from the transmitting- side memory at fixed periods. CONSTITUTION:On a transmitter side, a timing controller 14 generates write clocks when a transmitter-receiver 4a or 4b is excited and the clock generating period is the shortest immediately after transmitting and receiving waves, but becomes time sequentially longer. A write address counter 16 successively operates and reflect signals are stored in a transmitting side memory 12. The reflect signals are read out in the order shown by a read address counter 18 and sent to a receiver 2 through an ultrasonic vibrator 26 after main parts of the signals are stored. A vibrator 28 receives the signals and a timing controller 38 generates clocks by means of the actuation pulse of a synchronizing signal detecting section 36. A write address counter 40 successively operates and the reflect signals are stored in a memory 34 and, after main parts of the signals stored, the signals are read out and shown in a monitor 46 in the order shown by a read address counter 42. When such constitution is used, reflect signal information can be transmitted definitely, with the resolution of the information being more detailed as approaching a fishing net and rougher as going further from the net while holding a narrow transmission band.

Title: Spark discharge circuit for emission spectrochemical analysis
Inventor: HATSUTORI HIDEO
IPC: G01N21/67
Filed: 1983-11-25
Abstract: PURPOSE:To enable the generation of a spark discharge accurately at each time by charging a main capacitor with an induced current on the secondary side of a transformer while a trigger voltage is raised until the spark discharge starts to broaden the selection range of a discharge energy when exciting current is cut off. CONSTITUTION:A voltage of a DC power source DC is applied to a transformer Tr1 for a proper time length and current increasing with time flows through the primary side winding to accumulate a magnetic energy. Then, by cutting off between the transformer Tr1 and the DC power source DC, the magnetic energy is shifted to the main capacitor C1 for accumulating spark discharge energy with an induced current in the secondary winding. This operation is repeated desired times to increase the charged energy of the main capacitor C1 gradually while a trigger voltage is generated with a circuit whose output voltage rises with time whereby the trigger voltage is raised until the spark discharge starts in a discharge gap G2.
