Abstract: The present study investigates the self-citations of the most 
productive semiconductor journals by synchronous (self-citing rate) and 
diachronous (self-cited rate) approaches. Journal's productivity of 100 
most productive semiconductor journals was gathered from INSPEC database, 
1978-1997 through OVID. Data of citation frequency were obtained from the 
Science Citation Index (SCI), Journal Citation Reports (JCR) 2001 CDROM 
edition by the title-by-title search. The self-citing and self-cited data 
were drawn from the Citing Journal Listing and the Cited Journal Listing 
of the JCR CDROM version 1990-2001. Self-citing and self-cited rates were 
determined by the method suggested by the JCR. Eighty-seven journals 
common to INSPEC and JCR in semiconductor were selected as the object of 
this study and were listed for statistical tests. The results of the 
present study demonstrate that high self-citing journals are usually older 
than low self-citing journals. In contrast to the self-citing data, the 
journal self-cited rate is not closely related to the publication year but 
reflects the characteristics of various journals. Journals with a short 
time interval of publication are more possible with high self-citing and 
self-cited rates. Journals with higher self-citing rate tend to be more 
productive and receive more citation than journals with lower self-citing 
rate. The journal self-cited rate has no association with the number of 
articles that a journal published and the citation it received. A journal 
with a higher self-citing rate tends to be cited more by itself. The mean 
self-citing rate is 9.59% and the mean self-cited rate is 15.03%. There is 
a significant difference between self-citing and self-cited rates within 
the same set of journals. (c) 2006 Elsevier Ltd. All rights reserved.
