A method for forming an edge-chamfered substrate with a buried insulating layer is provided, which comprises the following steps: providing a first substrate (S10); forming an etching mask layer on surfaces of the first substrate, wherein said etching mask layer is formed on the whole surfaces of the first substrate (S11); chamfering a glazed surface of the first substrate and the etching mask layer thereon by the edge grinding (S12); by rotary etching, etching the first substrate which is exposed by the edge grinding on the etching mask layer (S13); providing a second substrate (S14); and bonding the first substrate to the second substrate with a buried insulating layer (S15). The method avoids the edge collapses and the changes of the warp degree in subsequent processes.

摘要:
Cardiac monitoring is disclosed in which thoracic impedance and EKG signals are gathered and processed for improved resolution and accuracy. EKG signals are adaptively processed by digitizing, filtering, differentiating and raising the resultant differential by a power greater than one to emphasize changes in the slope of the EKG signal. Blocks of the thus processed EKG data are analyzed to identify peak amplitude and to compare spacing between peak amplitude adaptively to more accurately identify R wave peaks. Stroke volume is determined from a thoracic impedance signal and its time derivative. Preferably, a time-frequency distribution is taken of the time derivative thoracic impedance signal after low- and high-pass filtering to identify B and X wave events in the signal which are used to determine ventricular ejection time and dz/dt.sub.min for a determination of heart stroke volume by conventional methods. Alternatively, stroke volume is determined by a new relationship between a product of a pair of impedances simultaneously sensed on opposing sides of a patient's heart at the peak of a heartbeat.
