but mainly for bare silicon wafers

SEMI E49-1104 (Reapproved 1211)

Plastic films/substrates for flexible displays change their dimensions by temperature and humidity

In addition new methods modifying the original Siemens process were investigated and were introduced in high volume manufacturing

Automation of material transfer is assumed to be provided through other services

G04400 - SEMI G44 - Specification for Lead Finishes for Glass to Metal Seal Ceramic Packages (Active Devices Only) Revision:SEMI G44-86 - Superseded but mainly for bare siliconThis specification defines lead finishes for glass to metal seal ceramic packages assembled with iron nickel alloy leadframe construction. It defines composition, properties, limits, and refers to appropriate tests for utility. The criteria detailed in this document applies to glass to metal seal ceramic packages, assembled with iron nickel alloy leadframe construction, which conforms to composition limits specified in MIL M 38510 as lead material
