摘要： A method for selectively removing a desired insulating film from a wafer surface. The method includes the steps of: preparing vapor containing hydrogen fluoride and water; keeping the temperature of the wafer surface higher than the temperature of the vapor by a prescribed temperature difference range; and supplying the vapor to the wafer surface. Due to the difference in responsiveness caused by the temperature difference, only the desired film, for example, the native silicon oxide film formed on a silicon layer surface, is selectively etched and removed by the hydrogen fluoride. It is not necessary to extremely reduce the water content in the reaction system, or to accurately regulate the concentration of the hydrogen fluoride gas.

摘要： A method for treating a main surface of a wafer on which a thin film having micro openings is formed with a treatment agent includes the steps of: making the thin film hydrophilic, supplying water to the surface of the thin film, and supplying the treatment agent in vapor phase to the thin film while spinning the wafer. The rendered hydrophilic thin film causes the water supplied to the surface of the thin film to form a water film having a uniform thickness on the inner surface of the openings as well as on the surface of the thin film. A vapor phase treatment agent supplied dissolves in the water film so as to treat the main surface of the wafer at the bottom of the openings. Even if the wafer is spun at high speed, the treatment agent permeates through the water film into the openings so as to uniformly and efficiently treat the main surface of the wafer.

摘要： A PCM digital signal is provided with double-interleaving and error-correction encoding to protect against errors occurring during transmission, which can be carried out by magnetic recording and reproducing. The PCM signal is processed as error correcting blocks of several data word sequences and an associated error correction word sequence, and the double-interleaved sequences are then transmitted as transmission blocks. Up to one erroneous word in each error correction block can be corrected by using the error correction word sequence. Any uncorrectable word can be compensated by substituting a synthetic word interpolated from immediately preceding and following data words known to be correct. The distance between successive data words is made as great as possible so that a long burst error is unlikely to affect the ability to compensate uncorrectable errors. To achieve this, alternate words of the PCM signal are distributed to odd and even groups of sequences, and the interleaving is carried out by imparting different delay times to the respective sequences such that the greatest delay time imparted to the odd sequences is less than the shortest delay time imparted to the even sequences. The error correction word sequence is provided with a delay time intermediate the greatest delay time of the odd sequences and the shortest delay time of the even sequences.
摘要翻译： PCM数字信号具有双交错和纠错编码，以防止在传输期间发生的错误，这可以通过磁记录和再现来执行。 PCM信号被处理为几个数据字序列和相关联的纠错字序列的纠错块，然后将双交错序列作为传输块传输。可以通过使用纠错字序列来校正每个纠错块中的一个错误字。任何不可校正的单词都可以通过替换从已知正确的前一个和后续数据字内插的合成词来进行补偿。连续数据字之间的距离尽可能大，使得长突发错误不太可能影响补偿不可校正错误的能力。为了实现这一点，PCM信号的交替字被分配给奇数和偶数序列，并且通过给各个序列赋予不同的延迟时间来执行交织，使得赋予奇数序列的最大延迟时间小于给予偶数序列的最短延迟时间。误差校正字序列具有在奇数序列的最大延迟时间和偶数序列的最短延迟时间之间的延迟时间。

摘要： At least one channel of digitized information is recorded in a selected number of data tracks by a record medium. The digitized information is encoded, modulated and then recorded in a predetermined number of tracks. For example, if n channels of digitized information are to be recorded in m data tracks, then each channel is recorded in m/n data tracks (m.gtoreq.n). A control signal is generated to include control data representing at least one of the following: (a) the number of data tracks in which each channel of digitized information is recorded, (b) the encoding scheme used to encode the information, (c) the type of modulation used to modulate the encoded information and (d) the relative speed of movement of the record medium. The control signal is recorded in a separate control track. Thus, the control signal represents the particular format in which the digitized information is recorded.
