Abstract: Methods of sealing a venthole of a micromechanical device. The venthole leads to a chamber that contains a device. A first laser pulse is applied to the venthole of a substrate of the micromechanical device for a first time period. The first laser pulse has a first laser intensity spatial distribution. Thereafter, a second laser pulse is applied to the venthole for a second time period. The second laser pulse has a second laser intensity spatial distribution that is different than the first laser intensity spatial distribution. The second laser pulse can be applied for a time that is different than that of the first laser pulse.

Abstract: Disclosed is a device for preparing a silicon carbide crystal including a crucible and a crystal expansion guide assembly. The crucible includes a crucible body and a crucible cover fixing a seed and covering the crucible body. The crystal expansion guide assembly includes a frame member and a tubular core member. The frame member is fixed to the crucible body, located between the crucible cover and a raw material accommodated in the crucible body, and provided with a through hole with a diameter greater than a diameter of a growth surface of the seed. The tubular core member is mechanically connected to an inner wall of the through hole. During a crystal growth process, the tubular core member falls off due to contact with a growth front of a crystal. The frame member does not react with the crystal. Thus, a large-sized crystal ingot with high quality can be obtained.
