amount of money otherwise put into correcting mistakes. Here, the old saying ‘failure is but the threshold to success’ comes in handy. This hackneyed maxim usually serves to encourage those who fail continuously. However, fast followers can learn from mistakes that others have made in the past and wisely choose to avoid similar mishaps.
Last but not least, follower companies
2.3 C-V graph
The measured MOS capacitance (called gate capacitance) varies with the applied gate voltage.
① Measurement of C-V characteristics
-Apply any DC bias, and superimpose a small (15 mV) ac signal
-Generally measured at 1 MHz (high frequency) or at variable frequencies between 1KHz to 1 MHz
-The dc bias VG is slowly varied to get quasi-continuous C-V characteristics
② C-V chara

4.1 RCA cleaning
RCA cleaning is a series of rinsing procedure prior to experiment with Si wafer. The purpose of the RCA clean is to remove organic contaminants (such as dust particles, grease or silica gel) from the wafer surface. There are three steps to be performed. The first step is to remove organic contaminant from surface of wafer. Second step is to remove any oxide layer

the decreasing prevalence of H. pylori may be playing a contributory role to the increasing prevalence of GERD in these regions
many patients with H. pylori–induced gastritis have involvement of both the antrum and corpus, decreasing parietal cell mass, reducing acid secretion, and elevating gastric pH, which may have a protective effect on the esophageal mucosa in patients susceptible to
