About Collaborative Alliance for Semiconductor Test (CAST) | Charter and Bylaws


1. Foster pre-competitive collaboration

Eliminate barriers to participation, enabling a broad membership and level playing field inclusive of all semiconductor industry participants with emphasis on manufacturing process cost, efficiency and yield beginning with wafer test and ending with shipment to the customer.

2. Research, develop and promote standards that enable industry productivity improvement:

Resource and drive specifications to enable efficient and effective interoperability while fostering an environment that encourages fast development, deployment and usage of specifications or standards.

  1. Standards for the interface between semiconductor equipment and the various other systems, both hardware and software to which the equipment is required to interface.
  2. Enable collaborative development of standards implementation to speed deployment and ensure compliance and compatibility.
  3. Invest in and direct research of mutual benefit to evaluate potential opportunities to improve test efficacy and efficiency throughout the design, validation and manufacturing processes.
  4. Ensure protection of member IP as well as timely disclosure of existing claims through a mutually agreed IP policy.

3. Perform pre-competitive benchmarks

Focused on: Quantifying end-user process efficiency and effectiveness, and identifying opportunities to improve end-user process efficiency via collaborative efforts.

  1. Ensure full acceptance of these definitions through a collaborative definition process.
  2. Utilize definitions to identify opportunities for new standards and improvements to existing standards.
  3. Utilize definitions to drive continuous process improvement by utilizing the Define, Measure, Analyze, Improve, Control (DMAIC) approach.
  4. Ensure the anonymity of member data through a mutually agreed policy.

4. Act as a representative and an advocate for the members

Focus on fostering a better understanding of their strategic value to the semiconductor industry. The targets will include the industry, universities, governments and other organizations:


  • Counter the belief that test is just a cost. Change the industry mantra from reducing the cost of test to increasing the value of test.
  • Encourage universities to support programs and curricula of benefit to the test industry.
  • Encourage engineers to consider the back-end as a career choice.
  • Act as a representative of the members to governments and other organizations.
  • Sponsor symposia to share the value add of test.

SEMI activities are a coordinated effort among competitors in the semiconductor equipment and materials industry and are, therefore, subject to antitrust laws. Although this coordination is perfectly legal under U.S. antitrust laws, we want to make sure that no antitrust risks are raised by the manner in which the SEMI program is carried out. Accordingly, these guidelines may go somewhat beyond the prohibitions of the law, but that is done in the interest of safety.

The penalties for violating antitrust laws can be quite severe, including large fines and even imprisonment of individuals found guilty of illegal conduct. Contrary to the popular belief that the government has relaxed antitrust enforcement, in recent years the Justice Department has recommended jail sentences for the majority of persons convicted of violating antitrust laws. Moreover, the U.S. Supreme Court has ruled that a trade association may be held legally responsible for the unauthorized, as well as authorized, acts of its members. Accordingly, every effort must be made to avoid even the appearance of impropriety.


As a basic premise, the goals of SEMI are clearly lawful. The proposed activities, if properly conducted, will not be found to violate the antitrust laws because they will not have an adverse effect on the competitive market place.

SEMI relies heavily on the judgment of SEMI staff members to see that topics which may give an appearance of an agreement that would violate antitrust laws are not discussed at SEMI meetings. The presence of a SEMI staff member at a meeting, however, should not invite probing to determine how far a discussion can proceed before it becomes apparent that it is improper and is cut off. Each SEMI member has the responsibility in the first instance to avoid raising improper subjects for discussion. This reminder has been prepared to ensure that participants in SEMI meetings are aware of this obligation.


The most common violations of the antitrust laws are agreements among competitors to fix prices or allocate customers. As for SEMI, the most important thing to keep in mind is that its purpose is to promote the semiconductor equipment and materials industry, sponsor education and training, and promote industry standards. SEMI does not market particular semiconductor equipment or materials products. Accordingly, it is not the business of SEMI to consider or discuss matters relating to product development marketing, purchasing, or pricing decisions of individual companies.

The Do's and Don'ts presented below highlight only the most basic antitrust principles.
Participants in SEMI meetings should consult counsel in all cases involving specific situations, interpretations, or advice.


1. DO NOT IN FACT OR APPEARANCE, discuss or exchange information regarding:
(a) Individual company current or projected prices, price changes, price differentials, markups, discounts, allowances, terms and conditions of sale, including credit terms, etc., or data that bear on prices, including profits, margins or cost.

(b) Industry pricing policies, price levels, price changes, differentials, or the like.

(c) Changes in industry production, capacity, or inventories.

(d) Individual company bids or intentions to bid for particular products, procedures for responding to bid invitations, or specific contractual arrangements.

(e) Plans of individual companies concerning the design, characteristics, production, distribution, marketing, or introduction dates of particular products, including proposed territories or customers.

(f) Matters relating to actual or potential individual suppliers that might have the effect of excluding them from any market or of influencing the business conduct of firms toward such suppliers or customers.

(g) Individual company current or projected cost of procurement, development, or manufacture of any product.

(h) Individual company market shares for any product or for all products.

DO NOTdiscuss or exchange information regarding the above matters during social gatherings incidental to SEMI-sanctioned meetings, even in jest.


1. Adhere to prepared agendas for all SEMI meetings.

2. Insist that meeting minutes be prepared and distributed to all participants, and object whenever meeting minutes do not accurately reflect the matters which transpired.

3. Understand the purposes and authority of each SEMI committee or other group in which you participate.

4. Consult with SEMI's legal counsel or your company counsel on all antitrust questions related to SEMI meetings.

5. Protest against any discussions or meetings which appear to violate the antitrust laws, disassociate yourself from any such discussions or activities, leave any meeting in which they continue and report the activity to the SEMI President and CEO so that similar conduct can be avoided in the future.

SEMI's policy is to discuss thoroughly with legal counsel any proposed programs or policy decisions before they are implemented. If any participant has a question as to the legality of a proposed course of action, the matter should be immediately referred to the SEMI President and CEO who will discuss it with legal counsel. In this manner, SEMI can ensure continued pursuit of its legitimate objectives with maximum protection for its participants.
