* Includes 16,274,255 shares of common stock of the issuer issuable pursuant to the terms of the Note (as defined below) and the 2003 Note (as defined below), representing 55.1% of the currently outstanding common stock of the Issuer and assuming the issuance of such 16,274,255 shares of common stock.

This Amendment No. 6 to Schedule 13D (this “Sixth Amendment”) amends and supplements the Schedule 13D (the “Schedule 13D”), Amendment No. 1 to the Schedule 13D (the “First Amendment”), Amendment No. 2 to the Schedule 13D (the “Second Amendment”), Amendment No. 3 to the Schedule 13D (the “Third Amendment”), Amendment No. 4 to the Schedule 13D (the “Fourth Amendment”), and Amendment No. 5 to the Schedule 13D (the “Fifth Amendment”) filed by the parties with the Securities and Exchange Commission (the “SEC”) on June 7, 2001, June 16, 2003, July 11, 2003, June 3, 2005, January 5, 2007 and July 3, 2007, respectively. Except as specifically amended below, all other provisions of the Schedule 13D, the First Amendment, the Second Amendment, the Third Amendment, the Fourth Amendment and the Fifth Amendment remain in effect.

This Sixth Amendment is being filed jointly by the parties to the Schedule 13D, the First Amendment, the Second Amendment, the Third Amendment, the Fourth Amendment and the Fifth Amendment.

Appendix B is amended to include the following information with respect to the executive officers and directors of the parties jointly filing the Schedule 13D:

Except as described below, during the last five years, none of the Reporting Persons, nor, to the knowledge of each of the Reporting Persons, any of the persons listed on Appendix A or Appendix B hereto (i) has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) has been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject

to a judgment, decree, or final order enjoining future violations of, or prohibiting or mandating activities subject to federal or state securities laws or finding any violation with respect to such laws.

As part of a settlement relating to managing auctions for auction rate securities, the SEC accepted the offers of settlement of 15 broker-dealer firms, including Merrill Lynch, Pierce, Fenner & Smith Incorporated (“MLPF&S”), and issued a settlement order on May 31, 2006. The Commission found, and MLPF&S neither admitted nor denied, that respondents (including MLPF&S) violated section 17(a)(2) of the Securities Act of 1933 by managing auctions for auction rate securities in ways not adequately disclosed or that did not conform to disclosed procedures. MLPF&S consented to a cease and desist order, a censure, a civil money penalty, and compliance with certain undertakings.

On March 13, 2006, MLPF&S entered into a settlement with the SEC whereby the SEC alleged, and MLPF&S neither admitted nor denied, that MLPF&S failed to furnish promptly to representatives of the SEC electronic mail communications (“e-mails”) as required under Section 17(a) of the Exchange Act and Rule 17a-4(j) thereunder. The SEC also alleged, and MLPF&S neither admitted nor denied, that MLPF&S failed to retain certain e-mails related to its business as such in violation of Section 17(a) of the Exchange Act and Rule 17a-4(b)(4) thereunder. Pursuant to the terms of the settlement, MLPF&S consented to a cease and desist order, a censure, a civil money penalty of $2,500,000, and compliance with certain undertakings relating to the retention of e-mails and the prompt production of e-mails to the SEC.

In March 2005, Merrill Lynch & Co., Inc. and certain of its affiliates (Merrill Lynch & Co., Inc. and its affiliates collectively, “Merrill Lynch”) reached agreements with the State of New Jersey and the New York Stock Exchange (the “NYSE”) and reached an agreement in principle with the State of Connecticut pursuant to which Merrill Lynch, without admitting or denying the allegations, consented to a settlement that included findings that it failed to maintain certain books and records and to reasonably supervise a team of former financial analysts (“FAs”) who facilitiated improper market timing by a hedge fund client. Merrill Lynch terminated the FAs in October 2003, brought the matter to the attention of regulators, and cooperated fully in the regulators' review. The settlement will result in aggregate payments of $13.5 million.

In March 2005, Merrill Lynch reached an agreement in principle with the NYSE pursuant to which Merrill Lynch, without admitting or denying the allegations, later consented to a settlement that included findings with regard to certain matters relating to the failure to deliver prospectuses for certain auction rate preferred shares and open-end mutual funds; the failure to deliver product descriptions with regard to certain exchange-traded funds; the failure to ensure that proper registration qualifications were obtained for certain personnel; issues with regard to the retention, retrieval and review of e-mails; isolated lapses in branch office supervision; late reporting of certain events such as customer complaints and arbitrations; the failure to report certain complaints in quarterly reports to the NYSE due to a systems error; and partial non-compliance with Continuing Education requirements. The settlement resulted in a payment of $10 million to the NYSE.

On March 17, 2003, Merrill Lynch & Co., Inc. (“MLC”) announced that it had entered into a final settlement agreement with the SEC regarding an investigation into two 1999 transactions with Enron Corporation (“Enron”). This agreement, in which MLC neither admitted nor denied any wrongdoing, finalized a settlement-in-principle in which MLC agreed to pay a total of $80 million in disgorgement, penalties and interest and other relief.

In September 2003, the United States Department of Justice agreed not to prosecute MLC for crimes that may have been committed by its former employees related to certain transactions with Enron, subject to certain understandings, including MLC’s continued cooperation with the Department of Justice, its acceptance of responsibility for conduct of its former employees, and its agreement to adopt and implement new policies and procedures related to the integrity of client and counter-party financial statements, complex structured finance transactions and year-end transactions.

On April 28, 2003, the SEC, New York Stock Exchange, National Association of Securities Dealers, and state securities regulators announced that previously disclosed settlements-in-principle had been reduced to final settlements with regard to ten securities firms, including MLPF&S, in connection with the independence of research. These settlements were approved by the United States District Court for the Southern District of New York on October 31, 2003. The settlements called for MLPF&S, among other things, to contribute $100 million for the funding of independent research and investor education over the next five years but did not require MLPF&S to pay any fines or make any additional civil payments. In 2002, MLPF&S had agreed to pay $100 million to settle allegations by the Attorney General of the State of New York challenging the independence of its research. MLPF&S entered into these settlements without admitting or denying the allegations and findings by the regulators, and the settlements do not establish wrongdoing or liability for purposes of any other proceedings.

In addition, MLPF&S has entered into settlement orders with several states over the past five years concerning various allegations of sales practice and related supervisory violations. Settlement orders have been entered into with the Commonwealth of Massachusetts (May 2000), the State of Maryland (December 1999), State of Wisconsin (August 1999), State of Vermont (March 2001), State of Delaware (July 2002), and the Commonwealth of Virginia (January 2004).

For further information, reference is made to the Form ADV of Merrill Lynch on file with, and publicly available on the website of, the Commission.

On June 2, 2005, Merrill Lynch Global Emerging Markets Partners LLC (“MLGEMP LLC”) purchased from PSi Technologies, Inc. (“PSi Technologies”) a $7.0 million aggregate principal amount 10.00% Exchangeable Senior Subordinated Note (the “Note”) for cash consideration of $7.0 million. Pursuant to the terms of the Note, PSi Technologies Holdings, Inc. (the “Issuer”) may elect to pay any of the accrued interest by adding it to the

principal amount of the Note, as the Issuer did on December 31, 2005, June 30, 2006, December 31, 2006, June 30, 2007 and December 31, 2007. As a result of the addition of approximately $2,005,939 in the aggregate of interest to the principal amount of the Note since its issuance, as of December 31, 2007, the Note may be exchanged for approximately 11,257,424 shares of common stock of the Issuer.

PSi Technologies issued to MLGEMP LLC a $4.0 million aggregate principal amount 10% Senior Subordinated Note on July 3, 2003 (the “2003 Note”). Pursuant to the terms of the Note, the Issuer may elect to pay any of the accrued interest by adding it to the principal amount of the 2003 Note, as the Issuer did on on June 30, 2005, December 31, 2005, June 30, 2006, December 31, 2006, June 30, 2007 and December 31, 2007. As a result of the addition of approximately $1,317,840 in the aggregate of interest to the principal amount of the 2003 Note since its issuance, as of December 31, 2007, the 2003 Note may be exchanged for approximately 5,016,831 shares of common stock of the Issuer.
