Full turnkey

AnSem takes control over the complete ASIC development and supply flow, providing a true one stop shop for its customers.

AnSem’s ASIC solutions are specified in close cooperation with its customers, tailoring the specific ASIC requirements to the customer’s detailed system needs and providing customer full control over the final product specification.



ASIC Definition

AnSem’s ASIC solutions are specified in close cooperation with our customers, tailoring the specific ASIC requirements to the customer’s detailed system needs and providing our customer full control over the final product specification.

Our partnerships with ASIC foundries, packaging and test suppliers allow us to balance your ASIC requirements with the limitations posed by the technologies used in order to optimize cost, performance and quality for each individual application.

Our ASIC definition phase includes:

  • Translation of system needs into ASIC needs in collaboration with the customer
  • Validation of the concept
  • Feasibility and architecture definition of the ASIC
  • Selection of semiconductor process and package
  • Quality, test and manufacturability aspects
  • Planning and risk assessment
  • Development cost and production price
  • Mutually agreed ASIC specification

Custom IC and ASIC design

Our IC design engineers have extensive experience designing challenging, state-of-the-art analog and mixed-signal integrated circuits that have consistently exceeded customer expectations. IC designs have been made in BiCMOS and CMOS technologies, ranging from 0.35μm to 40nm and from very low frequencies up to the 10 GHz range.

While we continue to push the boundaries in analog design, we always take care that our designs fit with your financial and timing budgets. So if you are looking for that ultimate breakthrough in full-custom analog IC design, be it in lowering cost, or reducing power consumption, or increasing integration levels or circuit performance, there’s really only one place to go !

Our ASIC development phase includes:

  • Analog and mixed signal IC design and layout
  • Intensive corner simulations and verifications
  • Custom layout of all analog sections
  • HDL coding of all digital sections, synthesis & P&R
  • Top level integration, layout and verification
  • Design documentation, user manual
  • Final ATE production test and qualification plan
  • Design Tape Out procedure

Prototype Manufacturing and Evaluation

We takes full control of prototype manufacturing, covering:

  • Masks preparation
  • Wafer processing
  • Package assembly

We then perform prototype evaluation, often in close cooperation with our customers, at our fully equipped in-house ASIC evaluation laboratory. The prototype evaluation phase includes:

  • Development of a detailed evaluation plan
  • Design and manufacturing of dedicated test hardware and software
  • Prototype evaluation and characterization over voltage and temperature ranges

ASIC Industrialization

We take full responsibility for the industrialization process, whereby the prototype design is made ready for large volume manufacturing, optimizing the design for test (DfT) and manufacturability (DfM), executing the different qualification tests and developing the industrial wafer and final test programs on the selected ATE machine.

The industrialization phase includes:

  • Product qualification
  • Reliability stress tests
  • ATE program development & optimization
  • Manufacturability assessment
  • Yield optimization
  • Transfer to volume production

Supply Chain Management

We provides full supply chain management, from taking in orders from customers, over managing manufacturing subcontractors and continuous monitoring of product quality, to management of inventory and transportation of final goods to customer’s global warehouses.

The supply chain management phase includes:

  • Customer order management
  • Management of manufacturing subcontractors (Foundry, Packaging & test)
  • Test cost optimization
  • Quality management: production monitoring, customer returns and failure analysis
  • Yield management: cost optimization
  • Management of obsolescence, security of supply, longevity of supply, etc.
