A system for halting operation of a hard disk controller when a write operation occurs during a servo positioning error condition including a memory cell for retaining an indication of whether a write operation occurred during the previous servo sector. A memory cell, such as a flip flop, is set on any occurrence of a write operation. With the reading of a next servo field, the output of the first flip flop is latched to a second flip flop. During a present servo sector, a servo positioning error signal is logically AND'ed with a write gate active signal where the write gate active signal is enabled if write gate is active in the present servo sector or write gate was active in the previous servo sector (as indicated by the output from the second flip flop.

The disclosure is directed to a double crucible Czochralski crystal semiconductor growing apparatus (10). An inner crucible (14) floats in a melt within an outer crucible (13) and a single crystal semiconductor billet (23) is pulled from the melt (16) in the inner crucible. An elongated tubular member (26), having at least one small aperture (33) in the wall thereof, provides a channel between the outer and inner crucibles. The tubular member (26) permits flow of the melt in the outer crucible (14) to the inner crucible (13) while inhibiting the diffusion of dopant material from the inner to outer crucible while any gas in the member will pass through the aperture (33).

The invention relates to a method of improving a surface of a semiconductor substrate which is at least partially made of silicon. Defects present in or on the semiconductor substrate can be really repaired to provide a semiconductor substrate with a high surface quality. This is achieved by a selective epitaxial deposition in the at least one hole in the surface of the semiconductor substrate. Generally, the deposition step is preceded by an etching step which removes the defects and leaves behind at least one hole that can be plugged or filled with the selective epitaxial deposition of silicon to repair the substrate.

摘要:
In an integrated free-fall detection device for a portable apparatus an acceleration sensor generates acceleration signals correlated to the components of the acceleration of the portable apparatus along three detection axes. A dedicated purely hardware circuit connected to the acceleration sensor generates a free-fall detection signal in a continuous way and in real-time. The free-fall detection signal has a first logic value in the event that the acceleration signals are simultaneously lower than a respective acceleration threshold, and is sent to a processor unit of the portable apparatus as an interrupt signal to activate appropriate actions of protection for the portable apparatus. Preferably, the acceleration sensor and the dedicated purely hardware circuit are integrated in a single chip and the acceleration sensor is made as a MEMS.
