摘要:
A semiconductor substrate is manufactured in which a plurality of single crystal semiconductor layers is fixed to a base substrate having low heat resistance such as a glass substrate with a buffer layer interposed therebetween. A plurality of single crystal semiconductor substrates is prepared, each of which includes a buffer layer and a damaged region which is formed by adding hydrogen ions to each semiconductor substrate and contains a large amount of hydrogen. One or more of these single crystal semiconductor substrates is fixed to a base substrate and irradiated with an electromagnetic wave having a frequency of 300 MHz to 300 GHz, thereby being divided along the damaged region. Fixture of single crystal semiconductor substrates and electromagnetic wave irradiation are repeated to manufacture a semiconductor substrate where a required number of single crystal semiconductor substrates are fixed onto the base substrate.
摘要:
An SOI substrate having a single crystal semiconductor layer the surface of which has high planarity is manufactured. A semiconductor substrate is doped with hydrogen to form a damaged region containing a large amount of hydrogen. After a single crystal semiconductor substrate and a supporting substrate are bonded to each other, the semiconductor substrate is heated to separate the single crystal semiconductor substrate in the damaged region. While a heated high-purity nitrogen gas is sprayed on a separation surface of a single crystal semiconductor layer which is separated from the single crystal semiconductor substrate and irradiation with a microwave is performed from the back side of the supporting substrate, the separation surface is irradiated with a laser beam. The single crystal semiconductor layer is melted by irradiation with the laser beam, so that the surface of the single crystal semiconductor layer is planarized and re-single-crystallization thereof is performed. In addition, the length of the melting time is increased by irradiation with the nitrogen gas and the microwave; thus, the re-single-crystallization is performed more efficiently.

A holder for holding a display device is divided into a first holder (5) and a second holder (6), and a light source housing chamber (10) for housing a light source (1) is also divided so that a work for mounting the light source (1) to the light source housing chamber (10) becomes easy. A first reflector (55) and a second reflector (65) integrally formed with the holder and having a reflecting surface corresponding to a light emitting part of the light source (1) are provided in the light source housing chamber (10), thus a certain space is secured around the light source, the light is efficiently incident to a light guide plate, and a separately formed reflector becomes unnecessary.

A compartment temperature adjustment switch 12 is provided for successively switching a target temperature of a compartment air conditioner through pushing operation of a push button 12a. The switch 12 includes the push button 12a, a substrate 22 fixed to the push button 12a, and light emitting elements 23 mounted on the substrate 22. The segments are selectively illuminated when the light emitting elements 23 are turned on, and a target temperature is numerically displayed on the push button 12a by a combination of illuminated ones of the segments. An information display portion is integrally formed with the push button 12a.
