Gentlemen and Ladies:

         We have acted as counsel for Fairchild Semiconductor Corporation, a 
Delaware corporation (the "Issuer"), and the Issuer's parent, FSC 
Semiconductor Corporation, a Delaware corporation (the "Guarantor"), in 
connection with the filing by the Issuer and the Guarantor of a Registration 
Statement on Form S-4 (Registration No. 333-26897) (the "Registration 
Statement"), with the Securities and Exchange Commission for the purpose of 
registering the issuance of up to $300,000,000 aggregate principal amount of 
the Issuer's 10-1/8% Senior Subordinated Notes Due 2007 (the "Exchange 
Notes") and the Guarantor's guarantee thereof (the "Exchange Guarantees") 
under the Securities Act of 1933, as amended (the "Act").  The Exchange Notes 
are to be issued in exchange for an equal aggregate principal amount of the 
Issuer's outstanding 10-1/8% Senior Subordinated Notes Due 2007 (the 
"Existing Notes") and the Guarantor's guarantee thereof pursuant to the 
Registration Rights Agreement among the Issuer, the Guarantor, Credit Suisse 
First Boston Corporation, BT Securities Corporation and CIBC Wood Gundy 
Securities Corp. filed as Exhibit Fairchild Semiconductor Corporation 4.02 to 
the Registration

Statement.  The Exchange Notes and Exchange Guarantees are to be issued 
pursuant to the terms of the indenture (the "Indenture") among the Issuer, 
the Guarantor and United States Trust Company of New York, as trustee (the 
"Trustee"), filed as Exhibit 4.01 to the Registration Statement.  The 
Indenture is to be qualified under the Trust Indenture Act of 1939, as 
amended (the "TIA").

         In connection with the foregoing, we have reviewed such records, 
documents, agreements and certificates, and examined such questions of law, 
as we have considered necessary or appropriate for the purpose of this 
opinion.  In making our examination of records, documents, agreements and 
certificates, we have assumed the authenticity of the same, the correctness 
of the information contained therein, the genuineness of all signatures, the 
authority of all persons entering and maintaining records or executing 
documents, agreements and certificates (other than persons executing 
documents, agreements and certificates on behalf of the Issuer and the 
Guarantor), and the conformity to authentic originals of all items submitted 
to us as copies (whether certified, conformed, photostatic or by other 
electronic means) of records, documents, agreements or certificates.  In 
rendering our opinion, we have relied as to factual matters upon certificates 
of public officials and certificates and representations of officers of the 
Issuer and the Guarantor. 

         We have assumed that the Indenture has been duly authorized, 
executed and delivered by the Trustee and constitutes a legal, valid and 
binding agreement of the Trustee.  In addition, we have assumed that there 
will be no changes in applicable law between the date of this opinion and the 
date of issuance and delivery of the Exchange Notes and the Exchange 
Guarantees.

         Based upon the foregoing and having regard for such legal 
considerations as we deem relevant, we are of the opinion that: 

         1.   The Exchange Notes have been duly authorized by the Issuer and 
when the Registration Statement has been declared effective, when the 
Indenture has been duly qualified under the TIA, when the Exchange Notes have 
been duly executed by the Issuer and when the Exchange Notes have been duly 
authenticated by the Trustee in accordance with the terms of the Indenture 
and issued and delivered against exchange of the Existing Notes in accordance 
with the terms set forth in the prospectus which is included in the 
Registration Statement, the Exchange Notes will be valid and binding 
obligations of the Issuer, subject to bankruptcy, insolvency, reorganization, 
moratorium, fraudulent

conveyance, fraudulent transfer and similar laws affecting creditors' rights 
and remedies generally and general principles of equity. 

         2.   The Exchange Guarantees have been duly authorized by the 
Guarantor and when the Registration Statement has been declared effective, 
when the Indenture has been duly qualified under the TIA, when the Exchange 
Notes have been duly executed by the Issuer, when the Exchange Guarantees 
have been duly executed by the Guarantor and when the Exchange Notes have 
been duly authenticated by the Trustee in accordance with the terms of the 
Indenture and issued and delivered against exchange of the Existing Notes in 
accordance with the terms set forth in the prospectus which is included in 
the Registration Statement, the Exchange Guarantees will be valid and binding 
obligations of the Guarantor, subject to bankruptcy, insolvency, 
reorganization, moratorium, fraudulent conveyance, fraudulent transfer and 
similar laws affecting creditors' rights and remedies generally and general 
principles of equity. 

         This opinion is rendered to the Issuer and the Guarantor in 
connection with the filing of the Registration Statement and for no other 
purpose.  We express no opinion as to the laws of any jurisdiction other than 
the laws of the United States of America, the State of New York and the 
General Corporation Law of the State of Delaware.

         We hereby consent to the filing of this opinion as Exhibit 5.01 to 
the Registration Statement and to the use of our name under the caption 
"Legal Matters" in the prospectus which is included in the Registration 
Statement.  In giving the foregoing consent, we do not admit that we come 
within the category of persons whose consent is required by the Act or the 
rules and regulations promulgated thereunder.

                             Very truly yours,

                             /s/ DECHERT PRICE & RHOADS
