Corporate Information



In 1985, Si-TECH was founded by Orlando Desilvestre. He was a pioneer in the semiconductor industry who worked in multiple companies such as M/A-COM, Unitrode, Frequency Sources (SkyWorks) and was one of the original owners of Spire Corporation. Si-TECH’s primary business was to be a broker of silicon wafers for the semiconductor industry. He felt that he could help fill a void between the major manufacturers and the small corporations, research and development labs as well as universities.

Si-TECH would purchase large volumes and overstock material and inventory them so that corporations could purchase the quantities they required. It was a win-win situation because the major manufacturers would sell the necessary volume to turn a profit and the small firms would purchase the quantity needed instead of having to be saddled with excess, unwanted material. For on going customer requirements, Si-TECH would stock the inventory necessary to keep a consistent supply chain while freeing storage space for the customer.

In the 1990’s, as the industry changed and evolved so did Si-TECH by trying to meet the needs of its customers and expand its base. The company began to offer processing services as well as other wafers such as Germanium and Gallium Arsenide wafers. The idea was a simple one to provide the customer with one stop shopping. The customer would make one call with his/her requirements and Si-TECH would do the leg work saving the customer time, energy and multiple purchase orders.

At the turn of the century, Si-TECH began to expand its products in order to become diversified and meet the demands of a larger market by selling cassettes, metals, sputtering targets and other products.

Si-TECH is celebrating over 30 year in business; showing the achievement and success of an idea that has grown over the years.


The simple mission of Si-TECH is to fulfill the same basic ideas it was created upon. It wishes to be a one stop shop to fulfill the needs of the customers using superior products and services. In this environment of time limitations, cost cutting and savings, Si-TECH continues to be a company willing to do the time-consuming leg work in order to find the products required by companies large and small. The idea of saving its customers time and energy looking for products and creating multiple purchase orders with strong customer service is the main focus and drive of the corporation today and going forward.
